Velda Cross-Flow Biofill + UV-C

Compact multi chamber filter + UV-C unit 9 watt.
The Velda Cross-Flow Biofill is a flow filter, which has several advantages compared to different filter systems. Both its cleaning capacity and its biological action are larger than that of current filters. This property, combined with its simple installation, slight maintenance and ultimate water filtration makes this filter universally usable. The Cross-Flow Biofill ensures that pond water remains crystal clear and healthy.

Clear water is the basis for the biological equilibrium in your garden pond, for pond water has a direct effect on the growth of water plants, the development of micro-organisms and the condition of fish. If all water values are correct and the microfauna functions optimally, it is a question of a biological equilibrium. In the majority of cases this can not be achieved without a proper filter equipment.

For many ponds a filter is a solution. On the one hand water will be kept clear by filtration, on the other water circulation ensures sufficient oxygen. The Cross-Flow Biofill filters pond water both mechanically and biologically. Mechanical filtration is based on the principle of removing organic and inorganic dirt particles and colourings. The principle of biological filtration is, to obtain better and quicker conversion of organic constituents by means of micro-organisms. A new biological filter which has been used for some time stimulates the activity of the microfauna and thus benefits plant growth.

In a Cross-Flow Biofill, a Velda Pond Heater of 150 or 300 Watt can be mounted. The heater element offers the possibility to use a Cross-Flow Biofill also in winter. Besides, the activity of micro-organisms is stimulated enormously.

Suitable for ponds up to 10,000 l
