you want a filter that will filter your tank 5 or more times a hour, no
matter if its Salt or freshwater. Sump or no sump. Look on the side of
the
filter package when buyig a filter it will tell you how many Gallons per
hour (GPH) it does.

Are you guys talking about reef tanks ?
I am confused... This recomendation would be
agains the reef tank idea. Maybe fish only tanks ?

Why would it be against a reef tank, when corals usuually require cleaner
water to survive ?
