How the SunSun CUV-136 Works

The CUV-136 clarifier uses linear water flow technology to direct pond water past the integrated UVC lamp. The UV-C radiation alters algal proteins, clumping algae cells together so they can be removed easily via mechanical and biological pond filtration.

This process not only clears murky pond water but also supports a healthy biological balance in your pond.
