Soon I will have to set up an overflow in my 180 I was looking at glass-holes.com but could anyone give me some idea of what size/gph
ect that would be best? Also what sort of return pump would I need, it's a 6x2x2 which is going I be a mixed reef. Or any tips in general about making an overflow and sump set up. I've never had a sump installed in any if my tanks. Thanks a bunch guys.
And girls. How rude of me.
