I was wondering if you can have too much filtration for a tank. When I upgrade to a new 55 I will be buying the Marineland emperor 400, which is for up to 80 gallons. Then I will have my aqueon filter from my 30 gallon just laying around, if it won't hurt anything and will add BB and keep water clearer I would like to use it also. Is 500gph too much filtration for a 55g?
