Ok, I investigated his tank Friday and Saturday. He made the tank with the quikwall by quikcrete and used drylok paint on it. (I found the can of paint in his garage) he used ge silicone to mount a styrafoam background he had made to the back. Now I made a UGF out of 1 inch pvc Pipe and nylon screen glued together in the tank shape with 1 inch pipe risers every 18 inches with a wavemaker powerhead hidden by the background. The pipe is sealed and I drilled holes in the pipe to suck water in thru it as the UGF. I dont have a digital camera handy my wife took it someplace and didnt bring it back lol. Next week he is having a cover installed that makes it easier to work with. I am currently doing his wet/dry and other minor "toys" I am debating a uv sterilizer at the moment. I do have an old autowater top off kit I am giving him in return for some trades. The equipment is already in the shed against his wall and we painted it to match the house, we also drilled the holes for the plumbing. He has an older RO unit he removed because it didnt make enough water for his taste that I get to install for him on the autowater top off for the sump. I will see if I can get some pictures from another friend who I think has a digi camera. We got hungry Sat, so I caught the catfish and being mean, cooked it and fed the 3 of us lol. I have arranged for another "fish friend" to trade some minor house repair for some of his "extra" fish. We so far have arranged for 2 clown knifes, several crayfish, several species of ciclids, a monster pleco, and numerous communty fish. I have a sneaky suspision the crayfish will quickly become knive food, as well as the non-agro fish.
