Enjoy your water feature without seeing green! Ideal for the homeowner who expects the best. Bitron C is a UV Clarifier with the highest level of efficiency. It boasts a longer dwell time - the time the water is in contact with UV light. The Bitron C is also highly effective in controlling algae and bacteria. The adjustable flow control optimizes water flow through the UVC chamber. The rotor - with automatic cleaning - is guided around the quartz glass tube by water flow and prevents debris from settling. The Bitron C 55 is for ponds up to 18,000 gallons using OASE flow-through filters, BioSmart and BioTec. The Bitron C 110 is for ponds up to 36,000 gallons. The Bitron C enjoys quick release technology for easy bulb replacement and an adjustable flow control to optimize water flow through the UVC chamber. The inspection window confirms UVC bulb is functioning. Enrich the habitat of your koi pond and let wildlife see their reflection with the Bitron C UV Clarifier. When used in conjunction with the AquaMax Eco Classic 3600 Filter and Waterfall Pump, AquaMax Eco Premium 4000 Filter and Waterfall Pump, ProfiMax Filter and Waterfall Pump or the BioTec Flow-Through Filter, the Bitron C qualifies for the OASE Clear Water Guarantee.
