PhosBan is a high-performance synthetic ferric oxide hydroxide granule designed specifically for the efficient removal of phosphate and silicate from both saltwater and freshwater aquariums. This advanced filter media works by adsorbing these undesirable substances directly from the water column, preventing their accumulation and the problems they cause for reef inhabitants. Crucially, once adsorbed, PhosBan does not release these substances back into the aquarium, ensuring a stable and healthy aquatic environment.

Renowned for its exceptionally high capacity, PhosBan offers a long-lasting and easy solution for maintaining optimal water chemistry. It is highly recommended by marine aquarium expert Julian Sprung for its effectiveness in achieving permanent control over phosphate levels. This 454g container provides a substantial quantity of media, capable of significantly improving water quality and clarity in a wide range of aquarium sizes.

This product is an essential tool for any serious reef aquarist or freshwater hobbyist seeking to combat nuisance algae growth and ensure the thriving health of their corals and fish. Its reliable performance makes it ideal for those looking for a simple yet powerful method to keep phosphate and silicate levels consistently low, contributing to a vibrant and pristine aquarium ecosystem without constant intervention.
