Hi
Just got a 40g tank with 2 holes drill on each side towards the top . Can one of them work as the overflow and the other as the return ? Or do I have to get a overflow box?
Also, if this is ok, what size submersible pump do you recommend and brand. Probably about 2.5 -3 ft of hose on the return with a 10g sump (haven't bought this yet) .
Thx!'
