Hagen offers peat in both granulated and fibrous forms. A highly desirable filter media which is very beneficial for aquariums containing plants, South American Cichlids, Tetras, Gouramis, Rasboras, Killifish, and many other species of fish originating from acidic waters. Peat will lightly stain the water a natural tan color, lower pH and KH values, and release natural substances, optimizing aquarium water conditions for many fresh water fish and aquatic plants.

The results will be reflected in optimized coloration, improved behavior and reproduction. Peat is also a positive factor in algae control.
