Hozelock Bioforce UVC 18000 Filter 2 x 11w UV 20-40mm Inlet/Outlet.Re

Bioforce is ideal for pond keepers who want simplicity, clear water and an attractive hidden filter system. Bioforce UVC is a pressurised filter that can be buried up to its lid so can be completely hidden near the pond. Being pressurised by the pond pump, water can be pumped up from the Bioforce to the top of a waterfall. Water is forced through the foam. Because the water is pressurised the foam can fill with more beneficial bacteria. Water then passes close to the UV lamp, separeted from it by a quartz glass sleeve. When the Bioforce becomes blocked the red button will rise up.This signals that the foam needs rinsing in pond water.
