Enjoy your pool more by making it healthier & cleaner by using ultraviolet water sanitizer. The Ultra UV from Paramount provides an additional layer of protection beyond the capability of chlorine or salt based chlorine generators. This allows the kids & pets to safely swim in the pool as it reduces eye & skin irritation. As water circulates through the Ultra UV chamber the UV light immediately inactivates 99.9% of micro-organisms and algae which are resistant to chlorine. This provides a cleaner, clearer swimming environment with zero harmful by-products and reduces the amount of chlorine needed to maintain an adequate level of residual sanitizer. Easy to install & operate. A perfect addition to any new or existing pools.
