Oase has 2 lines of UV (ultraviolet) clarifiers, Vitronic and Bitron C. The Vitronic line is a high quality UV at a great price. Vitronic UV clarifiers are simple, yet flexible UV clarifiers designed to operate with all filter systems, although they best suited for OASE BioSmart filters. UV's help in the reduction of algae and phytoplankton, as well as limiting the growth of harmful pathogens

The Bitron C line is Oase's professional grade of UV clarifiers, designed for larger ponds. They also comes with extra features such as adjustable flow control, which allows you to adjust the flow of water entering the UV to the correct amount, even if your pump is too large. Bitron C clarifiers also come with an automatic cleaning rotor to keep the quartz sleeve clean for optimum efficiency.
