I've got a new Emperor 280 bio-wheel filter. It has a place for a filter cartridge with carbon on the backside of it and also a place for a big extra media cartridge that it came with (right behind the wheel). I was wondering if I should just fill the extra media cartridge with carbon and put it in there, or use two filter cartridges instead, or put something else in the media cartridge besides carbon? Thanks for the help and suggestions.
