Hello guys! I bought a used 60 gallon tank for my future saltwater tank (FOWLR for now, possibly reef later on). It has a built-in intake and output system in the bottom of the tank that connects to a cannister filter in the cabinet, resulting in very few dead spots in the tank, and no unsightly hoses on the back of the tank. Now I just need a cannister filter for it! I've been browsing, but am very confused about how many gph I need. The big eheims I've seen to up to around 360 gph, for "up to 160 gallons". I thought flow had to be at least 10 times the capacity of the tank?? But I googled 6000gph filters, and it was only showing monster pond cannisters! Is there something I'm missing here??
