The Bioforce Filter range has been improved, they are compact and highly effective pond filters which make cleaning extremely simple. Bioforce filters now have higher pond size ratings, and come with Kaldnes K3 biomedia and reduced cleaning. The Bioforce 9000 has an 24w UVC. All Bioforce sizes have been with the following features for high performance and ease of use: Mechanical Filtration More efficient and less cleaning Through-flow coarse foams reduce filter cleaning frequency. Profiled foams present a larger surface area for the efficient removal of waste. Layered foams make thorough foam cleaning easier. Bioforce filters have a large biological capacity due to the use of Kaldnes which is scientifically proven and in widespread use in industrial water purification processes. As a result, it has vastly superior biological capacity compared to other biomedia used in pond filtration. When using the new backflush facility, water flow through the Kaldnes biomedia removes loose debris and old less active bacteria, stimulating bacterial activity as a result. UVC- for the efficient removal of green water UV efficiencyWe only use maximum efficiency quartz sleeves in our UVC system, which allow 29% UV efficiency for treating algae, compared to 30% and 50% for glass and plastic respectively. High-efficiency single-ended UV lamps and an in-built water turbulator ensure maximum water treatment and the elimination of green water. Bayonet fitting of the UVC lamp allows quick cleaning and lamp change as required. UV viewing point. Bioforce is now equipped with a specially designed indicator so that the user can safely see if the UV lamp is switched on and functioning. The range features an Easy Clean backflush facility for flushing debris out of the filter thereby extending the time between thorough foam cleaning. This is also aided by the use of new flow through coarse foams, which efficiently remove waste particles whilst also reducing cleaning frequency. This filter comes with a 2 year manufacturer warranty.
