Well the tank is springing back nicely. And my persistent algae problems are massively diminished. So while some of the leaves of plants have algae on them that they acquired several weeks ago, no new leaves have algae. And that is a nice change.

The Hygrophilia corymbosa is slowly filling in and getting bushier. I initially let it grow too tall before I trimmed it. Now I’m topping it off every week so that it will fill in better. The Hygrophila difformis snapping back. And my Cryptocoryne wendtii and Echinodorus ‘Rubin’ are both totally algae free! Only the Echinodorus bleheri - the sword plant - has any algae. But that plant is off the the side and not getting enough light, and it appears to be underfertilized too. I’ll have to look into that…

I’ve put in an Eheim autofeeder to make sure the new red 3R2’s are getting enough food, often enough. The upshot is that ALL the fish are getting more food. I can see them all fattening up, and getting larger. Good for them I suppose.

The overall tank is still unbalanced visually, and improving the aquascape will be the focus of my efforts this year, now that I’ve got this algae licked. Well, I say “licked”… the GDA on the glass is still there. But it is quite manageable - requiring one 15 minute session of glass cleaning every week. And that persistent algae on the sand has stayed away for a few weeks, thank goodness. So it’s all controllable.

The new red 3R2s are still hiding. Three of the five barely ever come out. If anyone is in the room at all, the skittish three hide. So I have no idea of they are coming out to eat. I hope so. I’m just hoping that they will get over this with time.

I made a number of important changes to the tank to get ahead of this aglae. I know you can only change one variable at a time if you want any idea of what does/does not work. But I was desparate to control my algae problem and changed multiple variables. Problem is, I just don’t know which one was responsible for the change, or what combination:

1. Started using a “siesta”, or 90 minutes in the middle of the day with no lights.
2. Reduced the photoperiod to seven (7) hours total time of lights on.
3. Eliminated macro dosing, except potassium.
4. Reduced potassium dosing way back to one tenth of its normal volume.
5. Reduced micro dosing back to one tenth of its normal volume.
6. Reduced CO2 back to around 15 ppm.

A lot of people will tell me some of those things are real “no-no”s. But it’s working, and it’s hard to argue with success. Over time I’ll pick up the CO2 dosing. And I’m sure I’ll be forece to tweak the macro/micro dosing. But for now, I’m happy to have the tank healthy.

Wow. Been a while since I last posted. Sorry.

Things in the tank have been going fairly well, all but the recent CO2 goof up I posted about. And the fact that I massively over-trimmed the plant AND simultaneously did a filter media change. So the tank has been recovering from that. But the operative word is recovering. But the big news is - NEW FISH! I love new fish!

In the first pic you can see two little 3″ (well almost 3″) reddish discus in the background. They are “3R2″s from Wayne Ng, a breeder/importer. My wife was jonesing for some red fish, and these were the best I could do. I got a total of five, and they are expensive little buggers.

I’ve actually had them for seven weeks. The first six were spent in quarantine. They were maybe 1/2″ smaller when I got them. They were healthy as can be. So after 6+ weeks I dumped them in the tank. But before I did that, I took my runt Cobalt out and put him in the quarantine - to see if it had any pathogens they couldn’t deal with, and visa versa. You can see the “runt” in the pic below behind one of the 3R2’s.

But to my dismay, I could not leave the runt in their tank. He is normally the most shy, skittish, beat-up upon fish in the tank. I guess that goes with being the runt. But once he got in with these little guys he decided he was BMOC, Hot Sh*t, Top Dog, and all that! He would NOT let my 3R2’s eat! As far as he was concerned, the food was HIS. Quantity did not matter.

So, knowing I was risking my whole tank - I dumped him back into it, so that the 3R2’s could get some food. About five days later i just tossed the 3R2’s in the main tank… since the cross-contamination test was effectively blown. I figured both populations looked healthy, so dump ‘em in and hope for the best.

As I stated up front, I got five new fish. But these pics only show two. Good reason… these fish are wicked skittish. Two of them will only come out when no one is around. One walks the line, but certainly will not come out for pictures. The two in the pics are pretty “up front”. But as I walked around with the camera they got nervous and retreated. That’s why they are in the background in the first pic. And from the difference you can see between the two pics, they darken up a lot when hiding near the plants.

Apparently 3R2’s are pretty skittish as a breeding line. But that said, my Cobalts hid in the plants for darn near a month when I first got them. So I think this is one of those “time will tell” sort of things.

My wife (and I - truth be told) wanted RED fish. Not orange. But orange is the color discus tend towards. If you see red discus - as far as I can tell - it’s either because they have been fed hormones, unnatural amounts of food supplements, or the tank light has been altered. Failing that, PhotoShop can always redden up your digital fish pics if needed.

I got these fish because I trusted the gentleman i bought them from - Al Sapetta - the owner of www.simplydiscus.com. Al’s a stand-up guy, and he knew my wife wanted red - and he knew of the natural orange tendencies of discus - and he recommended these fish. That is good enough for me.

I’m feeding them frozen blood worms, Tetra Color Bits (now renamed something like Color Granules) and a little bit of NaturalRose red color enhancer. So yes, I’m cheating. But not so much that it jeopardizes the health of the fish. Problem is, my other fish are eating it too! So if my blue Cobalts start looking purple, you’ll know why! LOL

More about the tank itself soon. But all is fairly well. But not perfect. Otherwise… why post?

PS - I forgot to mention! That darned runt is a runt BECAUSE he won’t eat Tetra Color Bits. All the other fish do - they got big, and he didn’t. Well, while bullying my 3R2’s he started eating the Color Bits, aparently just to spite them. WELL… since putting him back in the main tank he has participated heartily in the multiple Color Bit feedings and has grown VISIBLY in just one week. Sounds unbelievable, I know. But true.

A couple of weeks ago I posted saying I wasn’t going to trim my plants. Big mistake.

The hygro was growing out of the top, and was long overdue for a trim. Unfortunately I let it get too tall - too leggy. So when I cut it last week, I cut it way back. But the leaves that were exposed by that process were too old. When they were exposed to the direct light this week GSA set up on them badly.

That was made worse by the fact that I spent weeks without cleaning the GDA off the sides and let it get too bad. I had it where I could do a quick scrape every few days and the tank was fine. But by waiting weeks it got thick, and when I cleaned it it went all over the tank. Including those old leaves on the hygro. And it hit the wysteria pretty hard too. And because I let it get so out of hand before I cleaned it, it was unusually thick on the tank walls by the end of the week.

All this might have been avoided if I hadn’t neglected regular maintenance.

But I replaced the filter media on one of my OceanClears. Big mistake after a huge trim. The trim removes biomass, and the filter change took out half of my bio-filtration too, Stupid. But I did it. I wonder how long I have to be in this hobby before I stop making newbie mistakes?

So I ripped all the stems out, and the hygro, and cut it way, way back. And I removed the Ludwigia repens too. I hated to do that - I love that plant. But it’s getting warm in the summer weather - 85 degrees in the tank every afternoon - and it is just not dealing with the heat. All its old growth is algae covered, so it’s better out of the tank.

What went back in the tank was only 1/3 the plant mass of what came out. Now my tank has precious little biomass. That’s potential trouble. So I’m anxious to see what this week is going to bring.

Live and learn I guess.

Well, the Green Dust Algae got pretty nasty. I hadn’t touched the tank in weeks, and it looked like it, so I broke down Friday nite and cleaned it. There was so much GDA that after scraping it off gave the water a strong green tint. So I did an 80% water change too, just to get most of it out. And I’m still having trouble with some kind of green algae growing on the sand. So I gravel vacuumed up the top 1/2″ or so, Chloroxed it, and put it back.

I’ll have to go back and check my records I think it had been three weeks since I touched the tank. And doing so created a maintenance effort that was probably 3 hours in total. A good bit of work I’m afraid. Or, I suppose you could say 1 hour a week for 180 gallon aquarium isn’t too bad. Especially with plants and discus.

I obviously trimmed the plants while I was at it. It felt like a pound or two of trimmings were pulled out. Tank looks better now though.

These photos really look aweful. The depth of field - or rather lack thereof - makes the tank look flat. I need to get a better camera, because I can tell you these boring, unidimensional pictures, just don’t show what the tank looks like in real life… where you can see the layers of depth. It also makes the fish look like they’ve got no room, when in actual fact they’ve to all kinds of room. So one day, a new camera. But for now, here’s a few pics of my fish.

I’ve got two types of discus, Cobalts and High-bodied Leopards. Both sets purchased from Dan at Gulf Coast Discus. If you look hard, or click on on of the pics to pull up a larger shot, you can see that one of the Leopard’s tails is a bit raggedy. I’ve got two fish that get beat up by the other fish. The ragged tailed Leopard, and my runt Cobalt. I’m not sure the runt can be seen in these pics - he’s hanging to the background where it is safe.

Anyway, here’s some pics.

I’m tired of cleaning green dust algae. Tired of trimming plants. So I’m taking a break from maintenance this week.

Usually I’ll clean the tank on a Friday evening if we don’t go out. Or Saturday afternoon/evening if we do. But last night we didn’t go out, and I was tired. Didn’t feel like farting around with the tank. And this afternoon we are going to the SimplyDiscus.Com 2008 Northeast Meeting and Cookout. So it won’t get cleaned then. I’m sure that tomorrow I’ll feel compelled to clean. But I’m not doing it on schedule.

Actually it didn’t get cleaned last week either. So the plants have been at least two weeks without a trim. So some old leaves are getting algae - that’s natural. Others are rotting. Natural too. But that’s why regular maintenance is required.

And the green dust algae (GDA) is getting bad in some places. Here’s a pic. Not very good, and clicking brings up a larger one. In this you can see that the GDA really does need attention. And the crypts need old leaves trimmed off.

I chose this pic because it reminded me of something disconcerting this week…

Earlier this week I came in to feed the fish one morning, and there was a bunch of foam on the surface of the tank, up against the tank wall. Uh oh. Looks like protein film. Hmmmm. I wonder what died?

All the discus were there. But a couple of days ago I noticed that one or two of my cockatoo dwarf cichlids seem to be missing. I had four males and two females. This pic is a typical feeding shot. When I drop in frozen blood worms everybody comes out of the bushes in a hurry! Dwarf ciclids, corys, biota striata (zebra loaches), and ghost shrimp. They all love bloodworms. But now, no more than two or three male cockatoo dwarfs. At least one is gone. If I can get them to hold still long enough maybe I can count.

I’m not really up on these fish… I suppose one or two could be guarding a brood. I’ve got breeding caves hidden in the plants. I wouldn’t know. I just hate to think that one or two died. They were young, and apparently healthy. I quarantined them for almost six weeks, and hit them with all sorts of prophylactic meds. If that didn’t kill them, I’m concerned that tank conditions would.

But it has been hot this week. The tank temps have been climbing as high as 85-86 degrees F every afternoon. Maybe it’s time to turn on the air conditioners and bring the ambient temperature in the room down a bit. It’s definitely killing my Ludwigia repens. Could be giving my poor cockatoo dwarf cichlids a hard time too.

And speaking of hard times… my favorite plant forum plantedtank.net has been down for two days. And I notice that aquaticplantcentral.com is down for repairs. I wonder that there has been another attack on aquatic plant sites? Hope not. And I hope that whoever it is that does that discovers in a nasty way that there is karma in the universe, and that what goes around comes around. But mostly I hope everything is ok.

Well! The tank survived a year! No mishaps. No floods. No tank killing algae. Cool!

I would have posted sooner, but we have had house guests, and tank things had to wait.

Hardware

I had some work to do before I made it to the 1 year mark. I wanted to finish all my under the stand stuff. So I bolted down my second Ocean Clear filter that had been loose before. And I did a thing I had really been dreading… moving my water depth sensor.

I haven’t posted the technical details of my setup yet, but suffice to say I have an auto water change rig that does not require any floats or sensors in the tank. It detects a “full” condition with a water pressure switch in the stand that gets water through a bulkhead hole in the bottom of the tank. And so that little critters don’t crawl down the hole, in the tank it’s covered with a somewhat unsightly filter sponge. If you have noticed the patch of crypts to the front left of my tank, it’s there to hide the sponge.

Well I wanted to create an open area to the left of the tank, and that meant that I had to push those crypts further back and to the right a bit. But that exposed the sponge, so I had to unscrew it from the bulkhead, cap off the bulkhead, and screw it into a different, better hidden bulkhead. That’s a real PITA with a tank full of water and three inches of sand in the bottom of the tank. And none of that describes all the hardware I had to move under the tank. Anyway, maybe you can see why I procrastinated.

I’ve got a few additional changes to make, with the hardware waiting in the wings. But I don’t need any of it yet, so I figured there’s no harm in crossing the 1 year threshold without doing that too.

Now that the tank has been up a year, there are a number of long-term maintenance things to start doing. Like changing the carbon filters that strip the chlorine out of the water as I add it each night. And changing the UV filter light. And - though I don’t like the cost - the HQI hologen bulbs need to be changed. Drat! This is going to add up.

Fauna

Been a lot of changes this year in fish. My school of Green Neons (P. simulans) has lost a few fish. It’s getting pretty small now - no more that 30 I’d guess. And I recently added six juvenile cockatoo dwarf cichlids that are doing quite well. And my small school of Otocinculus catfish has gotten smaller. I think I’m down to less than 10. But that’s OK, they can be tough on discus sometimes.

But my shrimp are doing great. I’ve still got quite a few Amano’s. I’m guessing 25 or 30. They are hard to count in a planted tank. And I’ve got no idea how many of the orginal 100 ghost shrimp purchased for this tank are still around. But it’s a bunch. Every week I find a new one or two on the floor in front of the tank - or so it seems. But at that rate they should be almost all gone. But they aren’t and I don’t think they are breeding because I never see any juveniles. Either way, I’m glad they are still around because they are great at eating excess discus food.

And as for the discus, they are fine. Or at least I assume that since they are still breeding like rabbits. I have at least two pairs breeding every couple of weeks. Maybe three pairs. I have to admit I don’t pay much attention since all the eggs are toast in a tank full of neons, dwarf cichlids and shrimp. But knowing that they are breeding is my way of knowing they are reasonably healthy and stress free.

Flora

I’m going into the second year for this tank with something that I’m not really happy to call an aquascape. IMO it’s a little lousy looking - closer to what I refer to as JABOP, or Just A Bunch Of Plants. But I’m still working through the set of plants that will tolerate my ultra soft water and the warm water temps that discus need. And having somewhat low maintenance plants is also an important criteria they must all pass.

So another real aquascape is coming. But not yet. Crossing the 1 year mark I ripped out a lot, trimmed a lot, and moved a lot of plants around. So I’m letting things settle a month or so before I go messing with stuff. And just to manage expectations… my aquascapes are not set up to look good in pictures. They are set up to look good in person. For instance, the open area on the left is that way to attract and hold fish. The tanks right side is in a corner of the room. So that keeps fish closer to where the people watching them are. But it does not always make for the best looking aquascape in photos I’m afraid. Sorry.

Conclusion

It’s been a pretty good 1st year for the tank. Algae pretty much under control, even if it did take too long. Fish are fine, plants healthy, and that tank hardware pretty much installed and complete.

This next year I’m going to have to redouble my efforts to get this to a nice looking aquascape. I like a challenge, and that will certainly be one.

Two days after this picture was taken my tank will have been up for one year. And that pic was taken two days ago. So today makes 1 year! Yippee!!!

But this isn’t the anniversary photo. Maybe I’ll take that tonight. There have definitely been changes in the last two days.

It’s been a stable year for the tank. But a disappointing year in some ways too. And a year of learning.

The fish have been healthy. I did have one case of bloat in one of my discus. And I thought that I had lost most of my Ottocinclus catfish until I tried to put some Rotalla wallichii in the tank, and I caught them eating the tips. So I guess they are just hiding in the plants unless there is something really tasty to come out for. Same with my amano shrimp (cardinia japonica). I thought they were gone too, but when I did a big trim a couple of weeks ago, I found dozens of them. Hiding too I suppose.

I’ve struggled with algae in this tank. None of the bad varieties. Just green spot (GSA) on the plants and green dust algae (GDA) on the tank walls. Lots of “experts” will tell you that GDA in particular just means you have a healthy tank. But lots of people don’t have it at all. I don’t mind a little. A minor wall cleaning every week or two is fine. But in a 180 gallon tank, any more than that is work. And I’ve been working.

I’ve flirted with a number of fertilization dosing regimens, and have settled back on the one I started with: letting the N an P in my tap water supply those macros, coupled with that being produced by plants, excess food, and biological breakdown of plant matter, supplemented with daily potassium and limited daily micros. That seems to both keep my plants healthy, and keep away the thread algae that wants to appear in any of my tanks that have sand substrates coupled with Phosphates over 1.4 ppm.

Ultimately I think the reason why dosing normal levels of N & P did not work for me in this tank was that my plant mass to animal mass ratio could not sustain it. The ammonia excreted by the discus was not being utilized by the plants fast enough. The plants were being dosed good levels of nitrogen in my dosing regimen, and the ammonia (NH4) was not being used fast enough and was triggering algae growth. Not that you could measure any ammonia in my tank. But it doesn’t take much to encourage algae.

For the sake of my plant health - which keeps the algae at bay -I’ve had to make a compromise that really hurts. I’m adding small daily doses of baking soda (NaHCO3), Epsom Salts (MgSO4), and Calcium Chloride (CaCl2) to raise my KH and GH. I’ve gone to great lengths to make this tank as low maintenance as possible, with a reasonable degree of success. One major goal has to been to be free of daily maintenance - with the exception of fish feeding. But if I’m away, anyone can do that for me.

To accomplish that my ferts are injected automatically, and my water changes are done in small, daily, completely automated cycles. To that end I’ve tried to let my plants adjust to the extremely low KH and GH of my tap water, and it just hasn’t worked. They don’t thrive without more calcium and magnesium than my tap provides. And the baking soda helps keep the pH stable. So I’m stuck adding this stuff daily. So much for no daily maintenance. I’ll just have to figure out a suitable way to automate this too.

And finally, I’ve finally finished all of the technical changes to the equipment that supports the tank. I’ve not posted info on it yet, but a pretty elaborate setup support the tank. A year ago I still had an additional pump and filter to install, a few improvements to make to the plumbing, and I needed to move the “water depth sensor” tube to a different bulkhead opening in the bottom of the tank. With that last labor intensive item done this weekend, there are no more planned changes to the equipment under the tank.

So I find myself at the end of a moderately successful first year of this tank. The hardware supporting it is finished. I’ve got the algae under control. And have finally found plants that work well with these lights, at these fertilization levels, at the warm temperatures discus require.

On the down side, I’ve got to figure out a way to automate my daily GH/KH boosting. And I’m not happy with the aquascape. That will - no doubt - be the focus of my efforts this coming year.

PS - If you see the dark discus that appear to be sulking in the right corner, they aren’t sulking. They’re OK. They are just tending their eggs.

In my last journal post I said that I’d keep my hands out of the tank until the end of the month, when I passed the one-year mark for the tank. Well, those intentions were great… but I could not help myself.

Most of the stem plants were at the water’s surface, and I don’t want them to get too “leggy”. I’m not a good aquascaper, but if I have to hang on to stem plants to keep this tank healthy, I’d at least like them to be bushy and thick. So they were getting a bit too tall and I cut them.

Because I’ve been fighting excessive Green Dust Algae (GDA) on the tank walls for a number of months, and because it has been MUCH better in the last month or so, I’m worried about pulling too much plant mass out of the tank. So I took metal weights and wrapped them around the tops of the stems I trimmed, and sunk them back into the tank. So hopefully they’ll keep growing and plant mass will not be too adversely impacted by the trimming.

In the pic you can see that the Ludwigia repens to the left is not doing well at all. When I let it grow to the surface it is thrilled. But even nine inches lower than the surface and it starts to really suffer. Now, where I have it growing is not directly under the metal halides. This plant needs high light to thrive. But I’m hard pressed to believe that being 18″ from a 150 watt HQI lamp is not enough light to thrive. I just don’t buy it. Instead I think that when it gets really, really close to the light that the photosynthetic rate that results somehow gets beyond what ever else is holding it back.

I can’t be sure, but I suspect the problem is temperature. My temps fluctuate from about 81.5 to 83.5 during the day. And Ludwidgia - a native of North America - is a cool water plant. But supposedly it can tolerate warmer water. This is kind of my test.

Anyway… the some of the other stem plants I inserted to help with the GDA - Wisteria (Hygrophila difformis) and Green Temple (Hygrophilia corymbosa) - seem to be dealing with heat just fine. Since I’m personally fond of Ludwigia’s, I’d be really tickled if this gets healthy too.

This is a shot of my tank from yesterday. I’m approaching the 1 year mark for having this tank up. By that I mean plants and fish in the tank. That day was May 27th, 2007. I keep really detail records on my tanks (something I heartily recommend to everyone), so I know that is the correct date. Yet I am frustrated by the fact that I STILL don’t have an aquascape that I’m happy with. But I’m going to have to just chill on that, because I’ve stated on some forums that if I haven’t gotten control of the algae I’m battling by the one year mark, then I’m scrapping the aquascape and starting over.

Well, as it turns out, the algae is reasonable right now. But it’s only been “OK” for a few weeks - apparently due to a radical change in my fertilization regimen. So while I’d love to rearrange plants so that I could say that I crossed the 1-year mark having achieved a satisfactory aquascape, I’m going keep my hands out of the tank for the next couple of weeks. If the algae remains under control as it is now, I won’t scrape the tank, but will merely rearrange it to a more esthetically pleasing arrangement.

If you saw my AGA 2007 post, you will see that I started this tank with anubias all over the driftwood. Those anubias got (and continue to get) green spot algae (GSA) on old leaves like nobody’s business. So I ripped those out and tried to replace them with other plants - primarily crypts of various forms. You will also note that I removed all the lovely lotus plants I was growing. Those were sending roots into the sand and causing what seemed (to me) to be unhealthy conditions in the sand. So I ripped them out. I never intended to have plants rooted in sand. All the plants you see right now are either not rooted in the sand, or they are in shallow pots of ADA Aquasoil covered with sand.

From the primarily anubias and lotus arrangement I moved to a (shallow potted) ’scape of various rosette plants. Those all suffered from the intensity of the 2 150w halogens. The algae it created on their leaves caused constant trimming until the plants were just dim shadows of the huge plants they started out as.

And next I filled the tank with stem plants as an algae fighting measure. The tank you see today is a reflection of that.

There are a number of urgent aquascape changes that need to be made to this tank . But I’m gonna let it cross the 1 year mark before I mess with it in a major way.

IMO a planted discus tank does not do well with hard tinkering or rapid changes. If it is balanced, leave well enough alone. Or tinker very slowly. So keep posted. A better tank is coming. I hope. But it will take a month or so.

The home built Big Clear Kahuna tank - with the 2006 discus aquascape - met an untimely end. It had a massive failure of a seam. Can you say “75 gallons of water gushing onto my wooden floor!” ? My wife can.

I’ll post later on how I built that tank, and how you can avoid the mistake that I made on that one. It’s easy. But for now I’d like to share my submission to the Aquatic Gardeners Association (AGA) 2007 Aquascaping Contest. I got a new tank - this time a 180 gallon - and named it Son of Kahuna, after the dear departed.

These pics are pretty early in the tank’s life. It did not remain this way. The lights were just too bright for the anubias, and they had to be replaced. The green spot alage (GSA) they kept getting on their leaves was driving me nuts. But this is what the tank looked like in the fall of last year at photo submission time.

Additional Info
This tank and aquascape were designed to provide a visually pleasing planted environment for discus, while still requiring relatively low maintenance. The plants, fish, crustaceans, and systems supporting the tank, all work together to keep tank maintenance requirements low - currently one weekly 45-60 minute maintenance session. Multiple, small, automated water changes each night yield an equivalent of 50% water change every 3 days. Three tank outflows are plumbed thru the bottom of the tank, with two returns over the top. Pre-filters on outflows and return nozzles are obscured by plants. No equipment was removed for photos. CO2 in-line injection with Mazzei venturi. CO2 kept at 45 ppm by pH controller. Daily micro fertilization with 9 ml ADA Green Brighty Step 2. Potassium dosed to keep tank at 25 ppm at the beginning of each day (prior to uptake). Nitrogen and Phosphate are found in the tap water used in water changes, keeping the tank at 8 and 0.9 ppm respectively. Neither is dosed.

I went kinda “all out” on the technical aspects of this tank. I’m sure someone’s got a more technical setup somewhere, but I’ve not seen it. It certainly makes keeping a planted discus tank this size visually appealing (no equipment in the tank), and easy to maintain. I’ll post more details on that later.

If you read my post on the AGA 2005 Big Clear Kahuna, it’s worth noting that that tank never really took off. Plants would do OK for a few months, and then begin to die. This repeated multiple times. And the poor plant health (and all the silicates from the sand) prompted a nasty thread algae outbreak. Ultimately I tore the tank down out of frustration and found the source of all of my ills. A silver plated coaster! I had used one to prop up some cardboard keeping the sand separate from the soil as I was setting up the tank the first day. And I forgot to remove it. That coaster began to dissolve and leach into the soil. And silver is devastating to plant roots. Look it up. So there’s one stupid mistake to never repeat.

Anyway, after I tore the Big Clear Kahuna, I named my next tank Kahuna’s Revenge. And by that time I had decided that I had learned enough to try to keep some discus. It has a reputation of being hard - keeping discus in a planted tank. And it’s not easy. But I wouldn’t call it hard. There’s just a little extra attention to detail required. For example, many discus keepers regularly use medications that will kill plants. And may plant people use fertilization dosing levels that would make discus sick or unhappy. Like I say, it’s just paying attention to the details. But it’s not really hard.

These are the pics I submitted to the Aquatic Gardeners Association (AGA) 2006 Aquascaping Contest.

Additional Info
Daily dosing: 12 drops ADA ECA, 1.3 ml ADA Green Brighty, 25ml solution of K2SO4 (equivilent to 2.5 ppm K). Pressurized CO2 injection to 35 ppm. 20% daily water change.

You’ll note that I’m not adding dosing any nitrogen or phosphates. With my city water - which has about 7 and 0.7 ppm respectively - it’s not necessary. Plus with the discus and their copious amounts of food, they add a good bit of nitrates to the water. In fact, without that 20% daily water change it would have been tougher. And that 20% water change sounds like a lot of work. But I’ve got it completely automated. I don’t have to lift a finger.

I’ll post more info on that, should you be inclined to try it yourself. It sure eliminates the biggest time consuming chore in this hobby.

Mickey’s 20g was not my only entry in 2005. I had really finished that tank early in that year. My real project was a tank I build myself, from big panes of glass. It was a 75g, and since I used very clear low iron glass (no green tint) I called it the Big Clear Kahuna. The BCK, as it was known in a few forums, came to an untimely end. This aquascape itself was doomed.

But it looked OK early on. So here are the pics I submitted to the Aquatic Gardeners Association (AGA) 2005 Aquascaping Contest.

I was trying to create a biotope, the looks of which I had never seen anywhere else in planted tanks. I wanted it to look like the sandy bottomed bayous I played in as a kid on the gulf coast, with similar plants and fish.

Additional Information
Growing up on the Gulf Coast of southern USA, fishing in cypress forests, with their myriad mazes of cuts and channels made by the passage of boats and water, while holding such fascinating aquatic life, created for me a deep love of that environment. This is rendition of how such a cut through a cypress forest, like those I grew up passing though on boats, might actually look underwater. - - - Though great pains have been made to keep this true to a real cypress forest, a few practical considerations keep this out of the biotope category. Botia striata have been used for snail control, Crossocheilus siamensis for algae control. And Vesicularia dubyana on hidden rocks provides a temporary barrier between the two substrates, to be removed when the foreground is fully mature. - - - Many Nymphaea, like the N. zenkeri here, are not indigenous, but have been present in USA cypress swamps now for around 100 years due to introduction by humans. - - - The Riccia was unplanned, though it is native. It snuck in on the Hemianthus callitrichoides and spread to the Eleocharis acicularis. Since that was both lovely and quite true to the invasive nature of that particular native aquatic weed, it has been allowed to continue spreading along the bottom, just as it would in nature. - - - This is a “point-in-time” tank. It is hard for me to imagine a recreation of any cypress swamp without the ever present top level predators that inhabit them. These fish can eventually outgrow all but the largest of tanks, and will eventually require replacement by juveniles. While this may not be considered “sustainable”, neither is the use of any fish population that do not breed in an aquascape - they have to be replaced when they die. Once the predators are a bit larger, the SAE and the loaches will be replaced with larger, mature Lepomis megalotis (Longear Sunfish) to fill their niche within the tank. So the tank should be fun to watch for a year or so any way, while hopefully being somewhat representative of true conditions. - - - With the exception of the temporary addition of a background to provide contrast for photos, this is the way the tank looks every day in our family room. No equipment was added or removed, no special lighting used.

There were a few notable problems with this attempt at a Gulf Coast biotope.

First, those cypress stumps grew algae like nobody’s business. Even putting them in was a huge effort because they are incredibly bouyant. I had several pounds of slate bolted to their bottoms so that they wouldn’t float. But I had to toss them. The algae on them just got too bad.

Second, I had to lose the gar. I loved that fish. It was cool! But I found out (after the fact) that they are illegal to posses in my state. So I had it quietly tranported to a friends marine biology in a state where they were allowed. Bummer. I really liked that fish.

And finally… the bass! Or Mr. Piggie as we called him. That fish was a eating machine. And a regurgitating machine for that matter too. I could not keep fish in the tank with that thing once it got a few inches long. It would try to eat anything that moved. It made no difference if it was clearly too big to eat. If he could get his mouth around it, he would eat it, or kill it trying. And after it digested stuff - as much as it could - ir would regurgetate on the plants. Really looked nasty, and took a lot of maintenance. So Mr. Piggie had to go to a pond. Another bummer.

But it was fun trying to create a biotope anyway. If you are inclined try something similar yourself, I’m going to doing a review of Robert J. Goldstein’s American Aquarium Fishes, an invaluable reference on native American freshwater fish. And I’ve included a link to Jonah’s Aquarium, a great place to buy them.

I never planned on getting into the planted aquarium hobby. Truth be told, my son young Mickey got a cheap little plastic aquarium for Christmas a few years ago, and I was stuck supporting it. Needless to say we over stocked it, and had to buy a bigger one to fix that, but we over stocked that too. So we bought a 20 gallon tank. And I had a great idea… “Hey Mickey, if we put some plants in there, they’ll soak up all the amonia, and we can put in even more fish!”

Boy was I a chump. It didn’t work out like I planned, needless to say. But I did discover diatomic green water, and Internet forums where I could ask stupid questions. I could have done without the green water, but discovering aquarium plant forums was a wonderful thing!

The tank wasn’t much of an aquascape. But by the end of the year it was healthy and growing very well. So I entered it in that Aquatic Gardeners Association (AGA) 2005 Aquascaping Contest. It wasn’t a competitive tank, but it was fun to enter and be judged.

At any rate, I’m still a bit attached to this tank. My son Mickey helped me get it going, it’s where I started learning about planted tanks, and I had a ton of fun with it.

Well, here’s a pic of my current tank. I give all my tanks names, and this one is “Kahuna’s Revenge”. It seems that my bigger tanks have all met with untimely ends. The first I called Big Clear Kahuna (I’ll post more on that later). It was followed - in true Hollywood “B” movie tradition - by “Son of Kahuna”. After that take tank bit the big one in very dramatic fashion, I had to have another. And this is it… “Kahuna’s Revenge”.

It’s a 180 gallon planted community discus tank. It’s a lot easier to have a a big, heavily planted tank with a few tetras swimming in it. But discus look much more dramatic, and it’s a bit more challenging to do successfully. So being the masochist that I am, once I started planted tanks I was drawn to discus like a moth to light. And in true moth fashion, I’ve been burned. But at the moment the tank looks OK. Not great. But OK.

I say that because the the aquascaping technique is a bit lame at the moment. I’ve got some plants growing out and are left in bad positions temporarily. And a few plants need to be removed once others grow in. But it’s pretty healthy.

I set this tank up about 11 months ago, and I been vigorously battling algae for about 10 months, 2 weeks, and 4 days. In other words, the algae has not been gone long. More about that later. But it does seem to be on the retreat now. But it was a wicked, hard time getting here. Now I just need to let a little time pass so I can grow out the plants and rearrange to a better aquascape.

This is my first real post to my Journal. So take note of how the tank looks today. It’ll change. And if the past is any indicator, all the changes will not be for the better. But relatively speaking, it’s a good day for a 1st post. Some browsers will let you click on the picture for a larger (and much more attractive IMO) pic. If you can get to the larger pic, you can see one of the discus guarding its eggs on a leaf in the back right corner. Spawning is my “canary in the coal mine”. If they are spawning, I assume they are happy.

More later!
