Official Tetra Clrchoice Aquarium Filter

Put the finishing touches on your perfect pond with the Tetra Clearchoice Aquarium Filter! This easy-to-use filter uses mechanical and biological filtration to maintain clear and healthy garden or fish pond water. Over the course of a three-stage filtering process, this filter uses beneficial bacteria to naturally colonize the biological filtration media to turn harmful pollutants in pond water into relatively harmless nitrates, helping create a healthier and happier environment for your favorite fish.
