How the SunSun CUV-155 Works

The CUV-155 clarifier channels water through an inline linear system, exposing it directly to the 55W UVC lamp. UV-C light penetrates algae cells, destroying proteins and DNA, causing them to clump together for removal via mechanical and biological pond filtration.

This dual action not only clears algae but also maintains a balanced pond ecosystem.
