Clear Choice Out-of-Pond Bio Filter PF1

The Tetra Pond ClearChoice® BioFilter sits outside your pond and works to keep your pond clean through biological and mechanical filtration. The easy-to-use system moves water through two layers of foam media before creating ideal conditions for beneficial bacteria to colonize on the large surface of the mats.

The ClearChoice BioFilter also features a Venturi trickle-flow system which draws air into the in-flowing water, creating ideal conditions for the beneficial bacteria to decompose waste.

When combined, the 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.

Do not use pumps with flows that exceed 550 gallons per hour unless a flow control valve is used.
