Maintain a healthy and clear pond with TetraPond Clearchoice Biofilters. Ornamental fish can overload a pond ecosystem with ammonia and other pollutants. Venturi inlet aerates water and thus enhances bio-activity.
The ClearChoice external pond filter biofiltration removes these contaminants and ammonia using its advanced Trickle Flow and Bio Ring technologies.
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.
