Tetra Whisper Filter Cartridges; Small

Enhance the clarity of your aquarium with Tetra Whisper Filter Cartridges. These pre - assembled cartridges are a breeze to use right out of the box. Featuring ultra - activated carbon, they effectively absorb unpleasant odors and eliminate water discoloration. The dense double - sided mesh is highly efficient at capturing debris and fish waste, ensuring your aquarium water stays clean and fresh. They are incredibly user - friendly and should be replaced once a month. Specifically designed to fit Tetra Whisper PF10 and 3i Power Filters, they come in a convenient small 2 - pack.

Using your Tetra Whisper Filter Cartridges is super easy. First, make sure your Tetra Whisper PF10 or 3i Power Filter is turned off. Then, open the filter compartment and take out the old cartridge if there is one. Put the new pre - assembled cartridge in its place. Make sure it fits snugly. After that, you can turn the filter back on. Remember to replace the cartridge once a month. This will keep your aquarium water clean and your fish healthy. When storing the cartridges, keep them in a dry place. If you notice that the water in your aquarium starts to look dirty or smells bad before the month is up, it might be a good idea to check the cartridge and replace it earlier.
