UV (Ultraviolet light) is a versatile technology used for disinfecting water, other opaque liquids, hard surfaces and air. Using the same germicidal rays as the sun, but hundreds of times stronger, UV offers a reliable, cost effective, environmentally friendly alternative to chemicals and their resulting bi-products. UV Sterilization is a purely physical process not a chemical one so it doesn’t alter water’s chemistry, taste, smell or pH. Our UV sterilizers and clarifiers can be used to disinfect and remove harmful pathenogens from freshwater and saltwater aquariums as well as garden ponds.
