NO3:PO4-X 500ml – Biological Nitrate and Phosphate Reducer for Nutrient-Stable Reef Aquariums
NO3:PO4-X 500ml is a high-efficiency nutrient control solution by Red Sea, designed to biologically reduce excess nitrate (NO₃⁻) and phosphate (PO₄³⁻) in marine and reef aquariums. Its advanced formula includes a carefully balanced blend of organic carbon compounds and essential trace elements that support beneficial microbial activity, promoting the natural reduction of nutrients through bacterial metabolism.
Each component is tailored to sustain microbial diversity and balance the carbon, nitrogen, and phosphorus (C:N:P) ratio, essential for a stable biological environment. Unlike chemical adsorbents, NO3:PO4-X works gradually and safely, protecting sensitive organisms like corals and zooxanthellae from nutrient shocks or depletion-related stress.
The 500ml format is ideal for medium to large tanks or reef systems requiring long-term nutrient stability and precision dosing.
Main features:
Gradually reduces nitrate and phosphate biologically
Promotes denitrifying and phosphate-absorbing bacteria
Provides organic carbon and trace elements for microbial efficiency
Balances C:N:P ratio for stable biological control
Prevents zooxanthellae loss and coral starvation
Maintains beneficial microfauna and system biodiversity
Can be used as a carbon source in denitrators and biofilters
Suitable for SPS, LPS, and soft coral reef aquariums
Recommended dosage:
Begin with a low daily dose based on measured NO₃ and PO₄ levels
Increase gradually as needed to reach target parameters
Monitor nutrient levels frequently and adjust for maintenance dosing
Why choose NO3:PO4-X 500ml:
NO3:PO4-X 500ml is the go-to solution for serious reef keepers who demand safe, natural, and efficient control over nutrient levels. Its scientifically designed formula offers gradual and reliable nitrate and phosphate reduction while supporting the overall biological integrity of the tank—ideal for advanced reef systems.
