OK I think i have adjusted my tank size to be 30X30X36 and will use the over flow method mentioned before, so i will have three 2in bulk heads put in for the overflow and back up for a return pump I am looking at at mag 24 and a mag 36, with a twist though, i want to have the back pane of glass drilled to have 2 one in bulk heads put in.

One slightly below center of the back wall and one towards the top so that I would and should have superb flow with no addition pumps needed. If i calculated all right sump and tank should be well over 200-250 gal total, so my thoughts are a mag 36 would be ideal due to head preasures and that from the pump to top of tank would be close to 4 ft.

Thoughts?
