The Ilex 10,000 Multi-chamber filters consist of 3 chambers, each of which is filled with carefully selected filter materials:

1st chamber is filled with filter brushes for the mechanical filtering of the pond water
2nd room is filled with Japanese mats
3rd chamber is filled with AlfaGrog E25: 90,000 m2 / m3
AlfaGrog is a porous ceramic material: strong, wear-resistant and relatively light. AlfaGrog is pH neutral and does not react with other substances. It has an enormous surface for the adhesion of microorganisms compared to other materials.

In comparison: filter foam has a surface of approx. 3,000 to 6,000 m2 / m3. extra biofilter capacity is available with less space for the bio-media. AlfaGrog is very suitable for drum and multi-chamber filters.

These two chambers provide the ideal attachment option for beneficial, waste-reducing bacteria.

The bacteria in the filter consume the toxic waste from the water (proteins, ammonium, nitrite, etc.), which results in a natural processing of the waste in the water. Bacteria in the biofilm of the mats live on the constantly supplied waste products. By letting the water flow over the biofilm on the mats, beneficial bacteria get the chance to absorb food. The water must flow along the biofilm for a certain period of time in order to make the contact time with the biofilm long enough to allow sufficient degradation of waste products to take place. This is ensured with the Ilex 3 chamber filter.

All chambers can be cleaned separately for each filter compartment by means of a bottom drain. The multi-chamber filter can be used as a gravity filter or as a pump-controlled filter. In the gravity variant, the water enters the filter via a bottom drain, for example, and the purified water is pumped back to the pond. The filter is below or equal to the water surface. With the pump variant, the water is pumped into the filter and the outflowing water runs back into the pond. The filter is above the water surface of the pond.
