FREEPHOS-R is a high-performance, ready-to-use synthetic iron resin designed for efficient phosphate and silicate removal in both freshwater and saltwater aquariums. Its advanced granular structure offers exceptional porosity and surface area, delivering superior phosphate absorption capacity.

FREEPHOS-R is engineered to remain stable without breaking down or releasing particles into the water, ensuring a clean and safe environment for your aquatic life. It maintains a controlled residual phosphate level, effectively reducing phosphate without dropping it below 0.04 ppm—supporting a balanced and healthy aquarium ecosystem.
