SunSun CPA-20000 Pond FIlter UV 18W, 3170gph Easy Backwash

Product details

SunSun CPA-20000 Pond FIlter UV 18W, 3170gph Easy Backwash is a pressurized pond filter with an integrated UVC clarifier designed to run mechanical and biological filtration in one unit. It uses a pump-driven flow path through filter media and then through the UVC clarifier before returning the cleared water to your pond, helping reduce suspended debris while supporting beneficial biological filtration on the media. The built-in EasyClean backwash system is controlled with a switch so you can flush and clean filter sponges without fully opening the unit for routine maintenance. The filter is intended to be installed at the pond edge and connected to the pond with a suitable pump (not included).

Features:

• Pressurized pond filter combines mechanical debris trapping and biological filtration via beneficial microorganisms colonizing the media.
• Integrated UVC clarifier irradiates water in a flow-through setup to help control free-swimming algae.
• EasyClean “Filter” and “Clean” switch positions support normal operation and an automated cleaning cycle for the filter sponges.
• Cleaning mode rotates the filter sponges and drains the dirty rinse water through a dedicated drain connection (for example, for irrigation).
• Maintenance indicator helps signal when filter sponges need attention.
• Replacement guidance for the UVC lamp is provided in the instruction manual (lamp life based on hours of operation).
• All connections/technology are in the lid/cover, supporting concealment when needed (installation method depends on your pond setup).
