Help improve water clarity and manage green water with a compact UV sterilizer designed for freshwater and saltwater aquariums. The Hygger Sweeper Aquarium Clean Light is a submersible UV sterilizer that uses ultraviolet light to target and neutralize algae and microorganisms that can contribute to cloudy or discolored water.

Its small size, flexible installation options, and built-in timer make it easy to incorporate into both temporary algae treatment and long-term aquarium maintenance routines. Whether installed directly inside the aquarium or hidden within a filter chamber or sump, it offers a simple solution for hobbyists looking to clarify water with minimal visual impact.

Product Highlights
- Helps improve water clarity! UV sterilization can help reduce green water and algae growth, supporting a cleaner and clearer planted aquarium
- Flexible installation options allow the device to be placed directly inside the tank or in external filter chambers to maximize water exposure during outbreaks
- Built-in timer and various settings allow operation to be automated for both preventative maintenance and active algae management
- Two operating configurations. Use the included protective shield when installed inside the aquarium or remove it when installed in external filtration for increased exposure and sterilization efficiency

UV sterilizers are commonly used to help manage green water and improve water clarity. Results can vary depending on aquarium size, bioload, maintenance habits, and the underlying cause of water quality issues. UV sterilization targets free-floating organisms that pass through the unit but will not address algae growing on glass, hardscape, or aquatic plant leaves directly.
