Ideal for use as a water garden or fish pond filter.

The 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 Brand 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. This, when combined with the use of “Trickle Filtration” encourages the prolific growth of beneficial bacteria, which helps to keep the pond free of pollutants.

Recommended Pump
TetraPond recommends the TetraPond Water Garden Pump 325 GPH or 550 GPH. Do not use pumps with flows that exceed 550 gallons per hour unless a flow control valve is used.
ClearChoice BioFilter is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from need instructions there should be instructions as to when to clean filters and more importantly whether the loose plastic balls should ever be washed. This unit replaced an identical unit which I used for >5 years until the filters fell apart, and the container filled with water which failed to come out of the proper lower spout.

#1 instructions for the Clear Choice Bio filter PF1, suggest installing a UNIVERSAL Inlet fitting, in place of the venturi , in certain situations. Where do I get a universal inlet fitting 2 Can I purchase a replacement water inlet fitting, mine leaks.

Asked by: Murph001
That comes with the filter. If the venturi is leaking, the issue is either the filter needs maintaining (typically the spray bar needs cleaning) or your pump is not sized to it correctly. It may be too big of a pump. Also, the outlet hose must travel at least slightly downhill or water backs up in the filter, and leaks out. BREX

The water flow to the filter is not strong enough to circulate the water properly. He inoculated doesn't fill.

Asked by: Sandy18
Not sure what you mean by the second portion to your question, but flow rate is directly related to the pump size and installation of the filter. This filter requires a 300-500 gph pump, no larger, and 1" inlet tubing, plus 1.25" outlet tubing. Those are ID specs. Cut any excess tubing, you do not need several additional feet, be sure to have around a foot to two foot slack and no more. Also, check for any clogs or kinks in the tubing, and clogs in the inlet or outlet areas. BREX
