Actually, I'm planning to build a zoo prop tank. I want to do a 24Lx12Dx10H. 4 or 6 24" T5s, heavy on acentic, canister filter, blower, heater. Finally replace my tank flow with a vortech and use my 2 seios for flow.
The plan, so far, is to do a Inverted V across the length of the tank(imagine setting up a pup tent along the length of the tank) using that new okinawa tank concrete mix. I'd like to design it so I can slide frag plugs into holes along the sides of the "tent" and grow them out. That way they would be easy to remove later on. I dunno, just an idea.
