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

Ruben

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