Product details

SunSun CUV-111 11W UV Sterilizer is an aquarium/pond UV sterilizer designed to help keep water clearer by passing it through a UV chamber. The practical goal is to reduce “green water” caused by suspended algae, which can improve overall water clarity for fish and aquatic plants. Used as part of your circulation/filtration setup, UV sterilization works alongside your existing filtration rather than replacing it.

Features:

  • Helps control suspended algae associated with green water for clearer pond/aquarium viewing
  • Designed to be integrated with your pump and plumbing for continuous water treatment
  • Uses a UV bulb (11W) to support sterilizing/clarifying water as it flows through the unit
  • Built for installation and maintenance convenience for both new and existing water systems
  • Compatible with both fresh and marine water setups (when used appropriately in your system)
  • Includes multiple fitting sizes to support common tubing/plumbing connections

  • Model: SunSun CUV-111 11W UV Sterilizer
