How It Works

UV sterilizers kill free-floating algae, bacteria, and parasites as water passes through the UV chamber. Slower flow rates give longer exposure time (dwell time) and better kill rates. Algae control needs the least UV power, while parasite elimination requires 2-3x more. Replace UV bulbs every 6-12 months as output declines.
