In contrast to other similar filter products, Activex is for the colonisation of filtration bacteria. It contains a gel that turns the filter into a retention substrate, which the bacteria can grow on more rapidly and efficiently.
The microorganisms are fed by the safe gel substrate.
10 ml of Activex should be added per cubic foot of biological filter.
