Giant Biofill XL

The mechanical and biological operation of the filter materials, the possibility to treat the water simultaneously against floating algae and pathogens and finally the possibility to heat the water and provide it with oxygen, are arguments that count in favour of investment in the Giant Biofill XL, which guarantees that healthy and crystal clear pond water will be obtained. The basis of the Giant Biofill XL is a large and spacious filter unit with a gross content of circa 250 litres. For additional increase of the filter capacity, 2 filters (or more) can be connected to each other, using the connecting swivel that is supplied along. At the bottom, in the middle of the filter, there is a draining point. By simply opening the valve any sludge and dirt can be drained off.

The filter contains 4 removable cassettes, 3 of which have been filled with filter material.

• The first cassette is meant for the built-in UV-C Unit and the Mineral Filterstart supplied along. In the cover there is also a facility to connect an air pump.
• The second cassette is filled with bio balls. This filter material provides a proper filtering of dirt and an enormous growth potential for micro-organisms.
• The third cassette has been equipped with a so-called coarse Japanese mat. It filters the fine dust particles from the water and after an initial period it will contain billions of micro-organisms.
• The fourth cassette is filled with a finer-threaded Japanese mat, by which even the finest dirt particles will be removed from the water.

All cassettes can be taken out, so that the filter materials can be simply rinsed.

The built-in UV-C Unit supplied along can be simply mounted in the rotation mechanism of the cassette cover. The UV-C lamp will make the green turbid water of a pond crystal clear within a short period of time, whereas pathogenic parasites will be killed by the UV-C light. To start up the biologic process, Bacterial Filter Start has been added. Mineral Filter Start Tablets Mineral Plus benefit a balanced mineral contents and increase the hardness.
