Ok guys I know I haven't been around a while, but here it goes I am trying to build my own sump instead of buying one for ???? dollars. Any comments on improvements would be appreciated, It will be made out of a 55 gallon tank with the center brace removed, I will be using a 2800 HY drive return pump, a Natilus EX 48 skimmer. This will be for my 175 gallon bow front.
