This filter takes the quality of the Biotec range of pond filters and adds many extra features to create a superb filter. The Biotec 30 includes 2 rows of large brushes, which are sloped to encourage settlement of waste in the base. The water then passes through the Biotec's, 5 upright woven mat screens of different pore size, after which the very fine waste is filtered by 7 cartridge filters which are twice the size of the Biotec 10 cartridge. The Biotec pond filter has a 50mm drain (valve supplied) below the brush chamber and a small drain valve near the outlet. With the inlet at the top and the outlet near the middle the filter can be partially buried (provided access the to valves is possible) enabling the large tank to be partially hidden. A very impressive filter.

The BioTec 30 has been designed for large ponds, and particularly for ponds with Koi stock. The BioTec 30 has a sludge drain for the removal of solids. The special filter surfaces enable rapid break-down of large quantities of nutrients.

The Biotec 30 multi-zone filter has a new type of filter mat with varying thicknesses, in addition to the brush chamber. This accelerates filtration of the coarse pollutant particles and helps the microorganisms in the rear part of the filter to do their work care-fully and effectively.

Biotec 30 has been tested for ponds up to 130,000 litres.

What is Effective Volume ?
The effective volume is the quantity of water in your pond, plus an allowance for shallow and or ponds exposed to high levels of sunlight. Both of these situations will result in a higher than normal algae growth, and fish pollution. We advise that to ensure your that your equipment is correctly sized, the effective volume be considered the minimum size for the equipment you select. However do remember to check the details of the product you are interested in, to ensure that there are no other allowances or consideration specific to that product are required.
