Well, we got the holes drilled in my 58 gallon without breaking the tank! Now on to the plumbing. We are putting in a 40 gallon basement sump directly under the tank, but I could use some advice from others that have plumbed a basement sump. I am a bit nervous about the return pump vs flow thru the sump/skimmer. I am considering a triton system. Also wondering about wastewater and if that can be plumbed out of the house or just into the home sump.
