How Ultraviolet Light works in a Swimming Pool
Based on a forward-thinking blueprint for the pool and spa industry, SpectraLight emerged. Drawing inspiration from the treatment methods used in municipal drinking water systems, the science underpinning SpectraLight Ultraviolet was developed. This involves the utilization of a potent UV-C germicidal light ray, characterized by its high intensity, to pinpoint the DNA and RNA of various microorganisms such as bacteria, viruses, algae, parasites, and cysts.
Simple Setup
In approximately half an hour, you can have SpectraLight set up effortlessly through a three-step installation process. By seamlessly linking SpectraLight UV sterilizers between your current pool filter and the water line that feeds back into the pool, integration is a breeze. This compatibility extends to all types of swimming pools, encompassing even salt water pools.
