Each cartridge is split into two separate chambers: the first chamber contains zeolite to remove toxic ammonia, and the second chamber is the activated carbon chamber so that pollutants and odors get removed. The water finally enters the floss layer, where the debris gets trapped inside the cartridge. This helps keep your aquarium water crystal clear! For best results, replace cartridge every 4 weeks.

Good product, decent shipping time to Hawaii, and no other company could beat the price. I'd recommend it.
Can't find the replacements in the store and didn't want to buy a new filter. Good price too!
