I heard that you should get a filter that is larger then your tank size, so I have a 20h, so is a filter for a 30g good enough?
smomus said:How many gallons per hour (gph) does it filter? You want to shot for at least 5x the water volume unless you have fish with high bio-load or you are over-stocked then 10x is better.
