Japanese mat coarse for Cross-Flow Biofill - replaceable filter mat

The Cross-Flow Biofill from Velda is a flow-through filter with multiple chambers, which are filled with filter materials. The purification capacity is very good, as is the biological action. This feature, combined with the easy installation, low maintenance and ultimate water filtration makes this filter universally applicable. Very solid due to the nylon hose grommets and the convex lid.Flow-through filter compact and strongUV-C lamp kills floating algae and germsJapanese filter mat removes coarse dirt particlesActive filter carbon absorbs fine dirt particlesFiltra-Sub for optimal biological filtrationOptional: heating element in the filterOptional: complete set with pump and hoseEasy installationConnect the filter to a dirty water/pond pump for circulation of pond water. Use a filter hose to connect the pump outlet to the filter entrance. Attach a second hose to the filter outlet for return flow to the pond. Give the filter a place next to the pond and lower the pump under the water. Activate the UV-C lamp and the water flow by inserting the plugs into the socket. Read the instructions first!The Cross-Flow Biofill is equipped with an 18 watt UV-C Unit and all necessary filter materials and connection fittings. The ultraviolet radiation from the UV-C lamp kills floating algae and germs. Optional is the integration of a Velda Pond Heater (300 Watt). The heating element allows the filter to be used in winter as well. It also greatly stimulates the activity of the micro-organisms. With the Cross-Flow Biofill is and remains the pond water crystal clear and healthy.Pure water is the basis for the biological balance in your pond. After all, the water directly affects the growth of aquatic plants, the development of microorganisms and the condition of the fish. If all water values are good and the micro life is functioning optimally, there is a biological balance. A filter is a godsend for many ponds. On the one hand, filtration keeps the water clear, on the other hand, the water circulation ensures sufficient oxygen. The Cross-Flow Biofill filters the pond water both mechanically and biologically. Mechanical filtration is based on the removal of organic and inorganic dirt particles as well as colorants. The principle of biological filtration is to obtain a better and faster conversion of organic components through the use of microorganisms. A biological filter that has been implemented promotes the activity of micro life and thus stimulates plant growth.
