Is what I would do ,it (floss) will catch and hold small suspended particles. You may need to rinse this often until your tank clears but once the tank clears,,you would only need to rinse or replace it when you perform maint on your filter which despite claims to the contrary ,should in my view be performed monthly.
Beneficial bacteria need oxygen to thrive and if filter starts to become clogged with organic matter,then oxygen levels inside a sealed canister can slowly be depleted creating anaerobic condition which could have negative effect on your fishes .
I have seen this occur with Magnum 350'' I have used as well as the HOT Magnum canister filter.Evidence of such a condition would be fish acting listless and hovering near the bottom and or fish gasping at the surface. In moderately stocked tanks,this may not be as much of a concern as opposed to heavily stocked aquariums or those near capacity.
Is one of many reasons that I like the Bio wheel type filters or wet dry for tanks smaller than 100 gal. Bacteria(good kind) is exposed to more oxygen not to mention they are easily cleaned .
I am not against canister filters ,I just think people should consider that they may need cleaning more often than some suggest. Opinions Vary.
