PhosCore is an advanced phosphate and silicate removal media designed to help aquarists achieve cleaner, healthier water with minimal effort. By combining the proven nutrient-removal capabilities of aluminium oxide and granular ferric oxide (GFO), PhosCore rapidly targets excess phosphate and silicate before they can contribute to nuisance algae growth and declining water quality.

Its highly porous structure provides a large active surface area for maximum adsorption, while the durable media resists breakdown during use, helping to deliver consistent, long-lasting performance. Suitable for both freshwater and marine aquariums, PhosCore is an effective solution for maintaining low nutrient levels and creating a healthier environment for fish, corals and aquatic plants.
