So, my fiance bought me a 4x2x2 120 for my birthday, and I am in the process of setting the tank up as a planted Congo biotope. Well, that's what we're shooting for. We got to the house at around 1am and got home with the tank at 3am, which may possibly be the seediest hours of the day for craigslist pickups, but we went with it. The top brace was melted from metal halides, but it came with the stand and the Nexx filters with all of the extensions that had never even been turned on. The guy even threw in a protein skimmer that we can flip. Anyway, the stand was the standard brown pine, so we stained it ebony to give it a touch of class. I also went to Ace and got a 22"x2" piece of acrylic to silicone all the way across the brace. The went smoothly and I think it will hold up, considering the guy had originally fixed it with shipping tape.
After we had the basics covered, we decided to make a diy styro background, and tried our best to make it look as natural as possible. For the substrate we are just using play sand, but if anyone can chime in with a better biotope alternative, feel free! So, this is where it stands now-DSCF4739.JPGDSCF4741.JPG
The hanging fixture is just a diamond plate shop light that we spray painted with a bronze hammered finish. This will be our second shot at a planted tank. Our 55 we had planted was a mess. We used Flourite under pool filter sand, but every time you would put a plant in, the tank would be cloudy for hours. I have heard really mixed things about sand planted tanks, so if anyone has any input, I'd love to here it.
Possible stocklist- African Brown Knife, 4 species of polys, possibly leaf fish, and I've always wanted an elephant nose. (I understand that this may not be a "true" biotope, but as long as they're from the same continent, I'm content:) )

What did you use to seal the styro background? Also subscribed :p

I would personally avoid using sand for a planted tank, unless it was created specially for them, since it won't have any nutrients for them.

Personally, for all my planted tanks i've gone with ADA Amazonia II soil, although depending on what you plan on stocking in your tank there are other choices of soil you can choose, and i'm sure a lot of them are cheaper (price wise) too...

I guess it a lot will come down to the type of plants you want to grow, and how high tech you want to go... for example if your just growing anubias, then pretty much any substrate will do, but certain plants that maybe more demanding may need a proper plant substrate...

Eitherway, can't wait to watch this develop...
 
:popcorn:Cant Wait!:) Keep us updated!
 
As far as sealing the concrete, I mixed in acrylic fortifier into the mixture to make it waterproof. We made one for our African Cichlid tank that has held up well for about a year so far. No leaching, no chipping and the fish are happy as can be.

Now for the sand, I think I'll just be doing 3 to 4 easy to care for species of plants that should do well in the substrate. I know Val is pretty hardy and I think will do well. There will also be a lot of anubias and a low maintenance sword. There will be blue river gravel mixed into the sand so it won't be too compressed on the roots. Do you think this will work well?

Now to go rinse 150 lbs of sand! Pics to come later today!
 
Well, after running all around town to find the right pieces of mopani, we headed home and started putting it all together. I had a large piece of mopani from an old setup that was just collecting dust, and when put together with the two new ones made a really neat structure. While we were out, I picked up two anubias (I have no idea of the species), and some corkscrew val, which I know isn't native to the congo, but we'll call it an invasive to slip by :). I then added the gravel and started to plant.

When I woke up this morning it was almost all clear, but there is still a yellow haze to the water from the sand. I think everything turned out good so far, but it still needs some major heaps of plants. While I was at work I found a stray momma Java Fern leaf with about 6 babies on it and decide to stick them all over the drift wood to see how it turns out.

I still need heaters, more plants, and fish!
