Laguna Clear-Flo 4000 Water Clarifying Kits for ponds provide the ultimate combination of pump power and water filtration efficiency. Every Clear-Flo kit consists of an industry-leading Laguna Max-Flo 2400 Solids Handling Waterfall & Filter Pump and a 4000 pressurized pond filter eliminates green water and kills algae. The Laguna Pressure Flo 4000 provides mechanical filtration coupled with a powerful UVC sterilizer to produce a clear, clean and healthy pond environment for ponds up to 4000 gallons.

The Pressure-Flo 4000 is designed to work in tandem with a solids handling pump, such as the Laguna Max-Flo 2400 Waterfall and filter 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.

Dirt-free water then passes along an integrated 36-watt UV-C lamp, where it is exposed to ultraviolet rays that inhibit the growth of algae. Finally, water 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.

  • Laguna Max-Flo 2400 gph  Solids Handling Waterfall & Filter Pump (PT8248)
