Oase Zeolith 1 L.

Zeolite is a natural rock that reduces the growth of algae by binding nutrients. It helps to reduce nitrate and phosphate levels by binding ammonium and phosphates. In combination with other filter media, it ensures clean and clear water as part of biological filtration. The material is characterised by high absorption properties.

To maintain the positive effect of Zeolith, it should be replaced every 8–12 weeks.
