crystal clear Professional

High-performance filter medium for mechanical aquarium filtration

The innovative, patented 3D fiber structure of sera crystal clear Professional removes even the smallest turbidity from 10 µm (e.g. floating algae, sludge) from the aquarium water in no time and makes it crystal clear.

In contrast to conventional filter wool, the filter balls of sera crystal clear Professional are dimensionally stable and can be washed out and used several times. After washing, they are 80% reusable.

The high-performance filter medium sera crystal clear Professional is suitable for both freshwater and saltwater aquariums and all types of filters. The perfect addition to sera crystal clear Professional is sera siporax Professional, the biological filter medium.
