4-Step Cartridge Replacement:

1. Remove cover from filter.
2. Remove used cartridge from bio-holster by pushing down gently on the holster and pulling the tab on the filter cartridge upwards. Discard used filter cartridge. Bio-holster should not be removed or cleaned, as it contains living bacteria.
3. Rinse new cartridge under cold water to remove carbon dust. Insert new cartridge into bio-holster by aligning the key slot on the cartridge with key slot on biological grid.
4. Replace cover on filter. Note: Cover will not fit properly if filter cartridge is installed incorrectly. Cartridges should be replaced when water begins to enter the filter bypass and/or the cartridge becomes clogged. Cartridges should be changed every 4-6 weeks.

Large Filter Cartridges


I like these cartridges very much with my filter of over a year old. I may be picky, but they don't seem to last me as long as they are supposed to. Of course, I have been known to occasionally over feed. My bad.

Great value!


Great product at an unbeatable price. I will always buy my filters at That Pet Place!
