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.

I currently have a 46G bowtank running with a Red Sea Skimmer and a
Canister
filter. It's running great.
However, I notice the Canister filter doesn't suck/clean as much as I
wish.
The power head (with sponge filter) and the skimmer seems to be doing a
better job.

I tried to get into a sump but decided not to at the end, instead I'll
wait
upgrade to a tank with built in overflow/plumbing.

People without a sump, how many filters do you use/need?


TIA

p.s.: I replace C-filter media every 2-3 of months but start thinking it
might not be necessary.
