SunSun CPA-2500 Pond FIlter UV 11W, 1585gph Easy Backwash

Product details

SunSun CPA-2500 Pond FIlter UV 11W, 1585gph Easy Backwash is a sealed pressure pond filter with an integrated UV-C clarifier, designed to help mechanically and biologically clean garden pond water. The filter runs water supplied by a pond pump through filter media where beneficial microorganisms can colonize, then through the UV-C section to help reduce free-floating algae as the water passes in a flow-through reactor.

Features:

• Mechanical and biological pressure filtration: suspended dirt is removed by the filter sponges/media while beneficial microorganisms colonize the filter media.
• Integrated UVC clarifier in the pressure filter body for in-line water treatment as water flows through the unit.
• Easy, switch-style flush/backwash operation to clean the filter sponges/media without fully opening the system.
• Maintenance-focused design with the connections/technology in the lid area for tidier placement (including concealment when buried/covered appropriately).
• Installation guidance: place the filter protected against flooding and where it cannot fall into the pond; the manual specifies a minimum distance of 2 m from the pond.
• Biological start-up timing matters—after reinstallation the unit reaches full biological cleaning efficiency after a few weeks, and bacteria work best at about +10 °C.
• UV-C clarifier use is most effective when the biological filtration is established, since microorganisms need time to colonize the filter media.
