Phosphate Minus from Tetra reliably reduces high phosphate (PO4) levels in aquariums via microorganisms which naturally remove phosphate from the water. Because of this gentle process, this treatment is safe for use with all aquarium inhabitants. Tetra Phosphate Minus will not cloud the water during treatment and is suitable for use in all freshwater aquariums including those with soft water.
