Here's a quick crappy sketchup that I threw together to get some ideas going. The bottom portion is the 300 gal pond that I have set up right now. The big boy is in there for the time being but will be switched to the 350 once the other cats go into the big tank. The glass you see will actually be a wooden top that I will seal much the same as the tank. There will be three holes cut out for some filter socks. I've never used filter socks so if someone can tell me if this would be enough for mechanical I'd love to hear from ya. If not I have other plans also. Once the water passes into the center of the trough there will be three pumps located there. Two 5,000 gph pumps, and an 1800 gph pump. The 1800 gph pump is a return for a rugf I'm planning. The other two have their own barrels to feed water too. The white things are barrels that will sit on the wood just above the trough. The water will be pumped up to the top where a specially designed spray bar will spray water down through the biological material of choice. Once the water fills the barrels a lil over half way it will fall through the return pipes over top of the tank down through the water column. This should creat a very nice areation of the tank. I'm also thinking of sectioning off the sides where the pumps will be so that I can add lava rock, crushed coral, ect, whatever I might need. The center will be wide open and I could possibly house trouble makers in that section until big enough to go in the main tank. So let me know what you guys think. I know it's crappy, but only had a couple of mins to work on it.
