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.
