The Laguna Pressure-Flo pressurised UVC pond filter provides important water filtration functions that are essential for everyday pond maintenance: mechanical and biological filtration, as well as UVC sterilization It features a revolutionary patented Easy Clean Backwash-Cleaning System that completely cleans the entire surface of the foam filters, and has had significant improvements so is now even easier to use than before.

The Pressure-Flo 21,000L is designed to work in tandem with a Laguna Max-Flo 16,500L (PT8256) solids handling pump. With the filter connected to the pump, water enters the unit through a water inlet. It then passes through the mechanical filtration stage, consisting of highly durable foam filters that intercept and trap dirt and debris.

Next, the cleaned water enters a biological filtration chamber where it comes into contact with the BioRock biological filter media which remove ammonia, and harbour beneficial bacteria keeping the water healthy for plants and fish.

Dirt-free water then passes along a 36W integrated UVC lamp, where it is exposed to ultraviolet rays that inhibit the growth of algae. The benefits of having prefiltered water enhances the effectiveness of the UVC lamp, which in turn helps to reduce algae and reduce the risk of fish disease borne bacteria and pathogens.
Water finally returns to the pond thoroughly cleansed. This patented system is the only one of its kind. Backwash cleaning can easily and comfortably be completed in a few minutes without opening the lid. This feature ensures that the filter performs at optimal levels for many days and prolongs the time between full maintenance sessions. An easy-to-view cleaning indicator signals when it’s time to perform backwash cleaning.

The unit can be installed in or above ground for ponds up to 21,000L
