Oase AquaActiv Phosless

The Oase Phosless Filter Granulate is a granular filter media is designed to provide protection against algae. It works by binding excess phosphates from the water and lowering the risk of algae formations.

The second cartridge binds heavy metals such as copper and lead and sulphide too, which ensures that the water in your pond is left beautifully clean and clear.

This pack of two cartridges is designed to use in the Biotec Biotec Screenmatic Pond Filters, simply place in a fast-moving section of the filter.

Once bound the resulting phosphate can be used as a fertiliser additive to avoid waste. Oase recommends that the inserts are replaced every 6-8 weeks.

One pack contains 1 x Phosless (treats calcium, binds phosphates and heavy metals) and 1 x Phosless FS (binds iron, phosphate and sulphide) and will treat 10,000 litres of pond water.

Contains 2 cartridges.
