Hobby Aquarium resin Zeolith

A hard natural stone with pores, cavities, and channels. Zeolith has an absorbing effect, meaning the strong electrostatic fields of the cavities attract and hold pollutants and decaying substances directly. Zeolith promotes the rapid development of bacterial cultures, prevents algae growth, and serves as an ion exchanger and catalyst. We recommend the very practical use of the filter medium in the pouches HOBBY.
