Oase Filter Systems


OASE Biotec 18 & 36

Specifically, the new Biotec filters have an individual chamber, which is filled as standard with Zeolite, However, as the name indicates, the use of other filter media such as Oase Phosless is possible.

The Biotec filters are "activated" with the aid of the Teichkur set, consisting of strains of bacteria, special granules and a bio-stabilizer.

This results in the colonization of friendly bacteria which get rid of harmful substances by converting ammonia into nitrite, nitrite into nitrate and nitrate into nitrogen, which then volatilizes and is therefore removed from the pond.
