okay so i ordered 2 800 gph overflows and 2 quitone 3000 pumps for the returns. and i was just wondering how i should run my return line i was thinking of useing a scwd on each and have one in each corner and two in the middle. anythoughts on return lines and powerheads i was thinknig of saving up and getting a vortech mp40 and using a mj mod (1200) and the returns but im putting allot of time and money and research into this tank and i want some other opions and experiencs. and this is going in a 125 and the over flows are gowing in the middle of bothe sides from the center brac.
