Amazon.com Efficient Filtration for a Healthy Pond The TetraPond ClearChoice BioFilter works to keep your pond clean through biological and mechanical filtration. This easy-to-use system filters coarse debris and provides biological filtration media with massive surface area for beneficial bacteria to colonize and remove harmful pollutants. The ClearChoice BioFilter utilizes a unique Venturi system, which draws air into the in-flowing water, creating ideal conditions for the beneficial bacteria to decompose waste. Take a look at the information below to see how the ClearChoice BioFilter could benefit your pond. How it Works Stage 1: Pond water is pumped into the filter. It passes through the foam, which sieves coarse suspended debris from the water (Mechanical Filtration). Stage 2: The water from stage 1 then passes through the finer foam, which provides further filtration. Stage 3: The final purification process of the water occurs on the surface of the biological filtration media. Beneficial bacteria will naturally colonize on this massive surface area and convert the harmful pollutants in the water into relatively harmless nitrates, which are absorbed by the aquatic plants or removed in partial water changes. The Tetra Venturi and Trickle-Flow System The water inlet into your filter is fitted with an advanced Venturi system, which draws air into the in-flowing water, creating ideal conditions for the beneficial bacteria to decompose waste.
