How to Replace a Tetra Filter

Tetra aquarium filtration systems use replaceable activated carbon filter cartridges to remove toxins, unwanted particles, odors and other impurities from the water of fish tanks. The overall goal of Tetra filters is to ensure the health and safety of pet fish while providing clear water for better display and enjoyment. Tetra filtration systems also employ a Timestrip device that turns completely red when it is necessary to replace the filter. Timely filter replacement is necessary to ensure the health and safety of domestic fish.
