So i have an Aqueon 10 quietflow filter and i modded the filter media. At first i used some quilt batting that i loosened up and it was still restrictive to the flow even after cleaning. Then i decided to fit in some foam sponges inbetween the bio holster and an empty filter cartridge plastic. The new sponges have yet to clog up, so do i need to have filter floss or is using a sponge (looks similar to aquaclear sponge media) safe.
