so a simplish question, I have a 220 Marineland with corner overflows, each side has a 2" drain and a 1.5" return both utilizing a 1.5" bulkhead..... so my question is I have a question on the best method for setting up the overflow, should I go with the standard setup as described (pics below) or should I use both openings as drains on 1 side of the tank and returns on the other to push water across the length of the tank?
