I'm getting the rest of pieces for the sump build. I think it's like 1&1/2 inch drain for the overflow box ph-100 and 3/4 return. I'm going to Home Depot now. Flexible tubing is good or should I get hard PVC
or something ? The only other thing I have to do is create chambers. I'm going to go to the petco and see how much a 20 long is right now and then I guess go to a glass store and have them make me 4 pieces of glass. 1 to put after the intake drain from the over flow and then 3 more closer together to prevent bubbles?
