so ive been running a fluval 106 for a few months now, its my first external filter and the more i think about it the more i think ive got things backwards.... water flows into the filter, through a foam screen, then through the biomax in the bottom basket and then through the polishing pad and carbon in the upper basket. from my expreience of internal filters and just pure instinct.... shouldnt the water go through the polishing pad before the biomax?
