Small granules of activated natural zeolite for use in all kinds of water filter. It is suitable for water potabilization in the home. ZN AQUA is approved for use with drinking water according to UNE-EN 16070.

It is an excellent filter medium for aquariums as it captures ammonium ions due to its natural cation exchange capacity and high affinity for ammonia. It also acts as a host for the beneficial bacteria which colonise the microporous stucture and then work to break down the captured ammonia. It is an efficient solid particle filter also, and can remove solid particles down to 5 microns, keeping the water crystal clear. This size is ideal for small filters.
