PhosBan 150g by Two Little Fishies is a highly effective synthetic ferric oxide hydroxide granular filter media designed to purify both saltwater and freshwater aquariums. It works by actively adsorbing harmful phosphate and silicate compounds, which are common causes of nuisance algae growth and can negatively impact coral health and overall water quality.

This advanced filter media boasts an exceptionally high capacity for phosphate adsorption, ensuring efficient and long-lasting control of nutrient levels. A key feature is its ability to permanently bind adsorbed substances, preventing their release back into the aquarium water even when saturated. Renowned aquarist Julian Sprung recommends PhosBan for its reliable and easy application in maintaining pristine water parameters.

Ideal for reef keepers and freshwater enthusiasts alike, PhosBan 150g provides a crucial solution for maintaining a healthy and vibrant aquatic environment. By consistently reducing phosphate and silicate, it helps prevent unsightly algae blooms, supports robust coral growth, and contributes to the overall stability and clarity of your aquarium, making it an essential component for long-term success.
