TetraPond ClearChoice External BioFilter (Click Here for a detailed view at ClearChoice External BioFilters)
Experience 4 Stages of Clean Choice Cycle:
1) Intake - Water is pumped into top inlet and dispersed by Teickle-Flow spray bar.
2) Mechanical Filtration - Sponged debris is removed by filter sponge pads.
3) Bio-Filtration - Water trickles over the bio-rings that provide massive surface area for aerobic bacteria to thrive. Ventur inlet supplies oxygen for aerobic bacteria. The beneficial bacteria on the bio-rings convert ammonia into nitrites and the nitrates.
4) 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.
