I'm looking for some help plumbing my 180 built in dual overflow to my sump. I think I pretty much have it down, however, everywhere I see it shows the return starting from the middle chamber of the sump T'ing off right in the middle and then up to each overflow corner equally. I'm also running a Mag 18 in my return 1800 GPH.
Here is my problem. My sump is made to be [skimmer (16x15)]>[fuge (13x15)]>[return (7x15)]. How important is it that I have the split off from my return to the tank equal? Couldn't I put a valve in that T split to put more GPH in a side that has a longer pipe therefore equaling out? If I have to have them equal.
