Koi Market / UV Sterilizers

Huge selection of UV sterilizers and UV sterilizer replacement parts for your koi pond or water garden at the best prices online. UV Sterilizers are an essential tool in eradicating algae in your pond or water garden and achieving clear water. They work hand in hand with your pond filter. Water flows through the ultra violet light where algae are exposed, killed and collected by your filter. The best setup for your UV sterilizer is to place it after your pond filter. Placing it after the biological filter and mechanical filter ensures the UV sterilizer is tackling all microorganisms. It’s also very important to make sure the proper flow is setup specifically for your UV to ensure the proper amount of exposure to the UV light is given. Adjusting the flow can be done using a ball valve and a flow meter from to measure the flow of water going through the UV sterilizer.
