Its been awhile since ive been serious about reefing but im getting back into it again! So for years ive had a hang on back overflow and im totally over that now. I would like to know if a single 1.5" drain will be enough for my 75g tank or should i go x 1.5"? I will have most of my flow from power heads but would like to find out what the best through flow for a mixed reef? thanks for any help
