So i'm going to drill my 90 gallon tank and put some bulkheads in. My only problem is I don't know what size and how many I should have for the tank. It's going to drain down into a 55 gallon sump/refuge. Also for the size of bulkheads/quanity what kind of return and return pump GPH should I have? Thanks!
