TetraPond ClearChoice® Biofilters

Maintain a healthy and clear pond with TetraPond ClearChoice® Biofilters. Ornamental fish can overload a ponds ecosystem with ammonia and other pollutants.

ClearChoice® biofiltration removes these contaminants and ammonia using its advanced Trickle Flow and Bio Ring technologies. Trickle Flow filtration is up to 5 times more efficient than filtration in which the media is submerged, allowing the Tetra ClearChoice® filters to be smaller in size for a given pond size.

• Intake - Water is pumped into top inlet and dispersed by Trickle-Flow spray bar.
• Mechanical Filtration - Sponged debris removed by filter sponge pads.
• Bio-Filtration - Water trickles over the bio-rings that provide massive surface area for aerobic bacteria to thrive:
  Venturi inlet supplies oxygen for aerobic bacteria.
  The beneficial bacteria on the bio-rings convert ammonia into nitrites and the nitrates.
• Discharge and Nitrate Removed - Purified water is discharged out the bottom of filter to the pond. Nitrates can be removed from the pond by aquatic plants and/or partial water changes.

• 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 .75", 1" intake fittings
• Venturi inlet aerates water and thus enhances bio-activity
