Hobby Zeolith 5-8mm 1000 gr

Hobby Zeolith is a natural, highly porous rock used as a filter medium in aquariums. Its unique structure—featuring a vast number of microscopic pores, cavities, and channels—allows it to adsorb and retain unwanted substances from the water. Zeolite functions through strong electrostatic interactions while simultaneously acting as an ion-exchange and catalytic material. Its pores trap organic substances, decomposition products, and excess nutrients, helping to maintain clean and stable water conditions.
Hobby Zeolith can help with:
Reducing phosphate levels
Binding excess nutrients
Removing decomposition products and organic pollutants
Providing a surface for beneficial bacteria growth
Maintaining the aquarium's biological balance
Improving water clarity and quality
Limiting the growth of unwanted algae  ...More
