6-Month Pack: Each pack contains 6 aquarium filter cartridges—plenty to last and easy to use. For best results, we recommend replacing the filter cartridges at least once every four weeks to keep your aquarium clean. Frequent replacement of the cartridges effectively improves your aquarium’s water quality.
Superior Filtration Performance: The filter cartridge is composed of high-quality cotton, activated carbon granules, and bio-cotton. This three-in-one filtration system effectively removes harmful microorganisms and other impurities, promotes the growth of beneficial bacteria, maintains clean water quality in the aquarium, supports the healthy growth of fish, and keeps the water clear and transparent.
These filter cartridges are specifically designed for the OUKMAO Fish Tank Filter. Replacing the filter cartridges is very easy—just open the lid.
Installation without tools required: You don’t need to remove the entire OUKMAOFish Tank Filter from the aquarium. Simply open the top cover of the filter, remove the old filter cartridge, insert the new one, and close the cover.
