So I have a 20g or so sump and a 39 gallon DP. I have a pump pushpins 280 gph. Im pretty sure I need a more powerful one. And one that's not gonna break me. I was looking at the danner mag 5. I have about 3.5' of plumbing from the pump to the DT. So I have to count in that head. I don't want some piece of junk and I would like one that ran cool. I know ehiems are great but kinda outta my budget. Any recommendations?
