filtration??'s

kinda confused about filtration....

i have been informed that proper filtration for a tank should be ten times per hour. Is this correct? if so y is it that every filter you look at claims to be for a certain sized tank but only puts out a turn over rate of four times per hour i.e.

the eheim 2250 canister filter claims that it is a filter for tanks up to 264 gals. with a max pump performance of 264 GPH. (that is a turn over rate of one time per hour on a 264gal tank)

the fluval FX5 canister filter claims that it is a filter for tanks up to 400 gals. with a pump rate of 925 GPH and only 607 GPH with media. (with media that is only a turnover rate of 1.5 times per hour on a 400 gal. tank)

are canister filters the exception to the rule?? or am i reading my information wrong?

I think you have things a bit confused here.

Your tanks FLOW or water movement should be at least 10 times your tanks volume not filtration.

Yes to the above and turning over the water 24 times a day is good. You must also consider your live rock (assuming you have some) so your water is filtered "through"/around the rock and through the canister or sump. If through a sump (as I have) my Mag 7 turns over the the water at roughly 500 gal. and hour and I have a 55 gal. tank. That means that 500/50 = 10 times an hour.
