The Cyprio Bioforce 2000 is a pressurised pond filtration system manufactured by the UK-based company Hozelock, which makes a range of gardening and related products. It features a UVC (Ultra-Violet Clarification) system which keeps pond water clean and clear by killing micro-organisms with ultraviolet radiation. Hozelock recommends changing the UV bulbs in UVC-equipped filtration systems every 12 months for the best results.
