Zeo Carbon aktiv is a very effective multi-purpose filter material consisting of high quality activated carbon and ultra-fine zeolite.

It removes odours, pharmaceutical residues, chlorine and organic waste generated through conversion.

In addition, it reduces phosphates and ammonia and promotes a rapid bacterial culture.

These beneficial properties inhibit the growth of algae and make the water clean and free of toxins.

If some fish are on medication, the carbon filter should not be used.
