This Kit Includes:

Giant XL Filter, High Stream 15000 Pump, 2 x 36w PPL UV and Silenta 300 Air Pump

The Velda Giant Biofill XL 6000 Filtersets are composed of a filter, an UV-C Unit, a Silenta Air Pump, a High Stream pond pump, Mineral Filterstart and Bacterial Filterstart. The 15000 filter is based on the cross-flow principle. The water is passed through the first cassette, in which the UV-C Unit and optionally a Pond Heater (150 or 300) can be applied, to 3 removable cassettes with filter materials. The Giant Biofill XL 15000 Set is a justified investment, which guarantees a healthy and crystal clear pond. The basis of the Giant Biofill XL Set is a large and spacious filter unit with a gross content of circa 250 litres. 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. 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 microorganisms.
• 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.
