Filtration. New to canisters
Always had internal filters previously so new to this malarky.
Bought my external canister and it comes with three trays, came with media, two bags of ceramic and one of plastic balls.
Have since got carbon to replace the second ceramic but my question is should the media fill the trays or just be there to flow through and filling it would result in clogging?
EDIT: all trays also have a foam filter.
