Aqueon Quietflow 10 mods
So i have an aqueon quietflow and i decided to change out some sponges i used to replace the normal cartridge, but i feel that i want clearer water, so i removed the blue wet/dry part of the filter with the old mechanical sponge so i have a good bio filter, then i took an empty cartridge and stretched some quilt batting until it was as thin as paper, and i hot glued the batting to the frame. I squeezed the mechanical sponges to clean the sponges of poop and not the batting has the smallest layer of red gunk on it but the water level in the filter is making it overflow (bypass the floss). What am i doing wrong?
