Pond Filters » Tetra Pressurized

New from TetraPond! The remarkable Bio-Active Pressure Filter provides mechanical, biological and UV clarification — all in one rugged, efficient unit. Specifically designed for maximum ease of use and convenience. Features unique open-profile bio-activators for improved cleaning.

Back flush valve reverses flow to flush out accumulated debris and sludge quickly and easily. Oversized latches allows for easy opening. These filters may be buried for concealment. Robust construction — built to last.

1. Water is pumped from the pond.
2. Water under pressure is forced into the bio-activators which trap dirt and debris.
3. Beneficial bacteria convert ammonia, which is harmful to fish, into nitrates, which are consumed by aquatic plants. This is known as the Nitrogen Cycle.
4. Filtered water is forced up the center tube.
5. Filtered water is returned to the pond
