Zeolite & Alfagrog Filtration PouchZeolite and alfagrog has been used in water purification and filtration for years. A natural material, Zeolite will help break down fine particle s and dirt, reduce harmful nitrates and phosphates and reduce algae growth in your aquarium or pond. Zeolite does not degrade rapidly, and needs only to be rinsed through annually to keep in prime condition.Alfagrog is heat-blasted reformed clay which is highly porous, and acts as a highly effective biological filter fostering beneficial bacteria in all the grooves and crevices. It is regularly used in systems to treat and filter drinking water, and is perfectly safe for use in ponds and aquaria.If you are finding that your pond or aquarium struggles to process nitrate, phosphate or is stubbornly cloudy, Zeolite can help reduce and prevent such issues. Add these pouches to your filter or place directly in your pond or aquarium.Supplied here is a sealed mesh filter bag pouch containing approx. 200g of mixed Alfagrog and Zeolite.
