Ok, I have a Rena XP2 on a 55 gallon tank, but I've been thinking about a HOB filter since I hate cleaning the thing. I have a question; would it be better to buy 2 HOB filters that are made for 30g tank, so added up it would be for a 60 tank and 300GPH. It's the Penguin 150 Bio Wheel filter link listed below or would it be better to buy the Marine 400
