I have an aqua clear 30 power filter on my ten gallon. It is three stages, and has a flow rate of 150 gallons per hour. I was just wondering if there where any benefits to having more filtration. I am thinking of upgrading the filter (again) to some thing with a higher flow rate and more bio media. I was thinking maybe the fluval c4... Also my ten gallon's hood has a little whole in the back cut out for one smaller filter, and the aqua clear thirty tilt PERFECTLY. But if I get a better filter I need to cut out some of the plastic to make room for a bigger filter...
