Maintain a healthy and clear pond with TetraPond Clearchoice Biofilters. Ornamental fish can overload a pond ecosystem with ammonia and other pollutants. ClearChoice biofiltration removes these contaminants and ammonia using its advanced Trickle Flow and Bio Ring technologies.

Features:
* Easy out-of-pond accessibility and simple maintenance.
* Mechanical pre-filter sponges-remove suspended debris to improve water clarity.
* Bio Ring media provide massive surface areas for beneficial aerobic bacteria to adhere to and multiply. Aerobic bacteria eat the ammonia toxins created by fish waste and decomposing plant materials.
* TetraPond internal spray systems and Trickle Flow technology disperses pond water slowly and evenly through the Bio Rings ensuring that there is sufficient oxygen to provide optimal biofiltration conditions.
* 1.25 drain fitting
* Interchangeable 3/4in., 1in. intake fittings
* Venturi inlet aerates water and thus enhances bio-activity
