Brightwell Aquatics Extrax Phos Spherical Media for Phosphate Silicate Removal in Freshwater Planted Reef Aquariums Fast-Acting High-Porosity Nutrient

Brightwell Aquatics Extrax Phos is an advanced phosphate and silicate adsorption media designed for efficient nutrient reduction in reef, marine, freshwater, and planted aquariums. With a highly porous spherical shape, Extrax Phos offers maximum surface area and optimal water flow without clumping or restricting filtration. This unique structure helps promote faster phosphate removal and longer media life. Phosphate levels above 0.05 ppm can affect overall tank clarity and health. Extrax Phos works by trapping reactive phosphate and silicate, helping maintain a balanced, low-nutrient environment. It's especially effective in systems with high feeding rates, large bioloads, or visible nutrient issues. Unlike some traditional phosphate media, Extrax Phos does not crumble, release trapped nutrients, or leach compounds back into the water. It’s safe for use in all freshwater and marine setups and can be used continuously as part of a long-term nutrient control plan. Use in a canister filter for active filtration or a 150µm mesh filter bag for passive use. Pre-rinse before first use, and place in an area of medium flow to maximize contact time. Replace when phosphate levels stop decreasing or begin to rise again. Extrax Phos is a powerful tool in maintaining crystal-clear water and balanced nutrient levels—but works best alongside proper feeding, water changes, and regular maintenance.
