Hi all, I want to add an overflow to my 40breeder. I want to split the tank.a quater of the tank will be used as an overflow and return as well. Maybe I could use acrylic or glass. I think I saw some frag displays or something like that.basically,like a biocube how it has the. Chambers in the back.I would like to make a concept similar to that,but on the side of my tank.Any ideas or thread you could point me in that direction?
