Red Sea NO3:PO4-X Biological Nitrate & Phosphate Reducer 16.9-oz

Control excess nutrients and prevent algae outbreaks with Red Sea’s NO3 and PO4-X Nitrate & Phosphate Reducer. Red Sea Products advanced solution is a carefully balanced blend of carbon compounds, each supporting different strains of beneficial microorganisms, all in a reef-safe formula. By encouraging the growth of natural nutrient-reducing bacteria already present in the aquarium, it provides a highly effective and sustainable way to lower nitrates and phosphates.

As a core component of Red Sea’s Algae Management Program, NO3 and PO4-X offers a controlled biological reduction process suitable for all reef and marine aquariums. Regular aquarium water treatments testing combined with proper dosing allows hobbyists to manage nutrients precisely without causing undesirable side effects to corals, fish, or invertebrates. Unlike chemical removers, this method supports a natural balance within the tank, ensuring long-term stability and healthier conditions for marine life.

Key benefits include: consistent reduction and maintenance of nitrate (NO3) and phosphate (PO4) levels, cost-effectiveness, complete reef safety when dosed correctly, and a controlled approach to nutrient management. With NO3 and PO4-X, aquarists can enjoy clear water, vibrant corals, and a cleaner, healthier reef environment.
