Ultraviolet clarifiers are the ideal choice to help prevent green water caused by algae blooms in backyard ponds and water gardens. Our complete line of quality UV sterilizers and UV clarifiers can help ensure a clean and healthy pond year round. UV lights function by damaging the cellular structure of free floating algae, causing it to clumb and sink to the bottom of your pond. From here, the dead algae is easily removed by your pond filter.
