NO3:PO4-X 5000ml – Biological Nitrate and Phosphate Reducer for Large-Scale and Professional Reef Aquariums
NO3:PO4-X 5000ml is Red Sea’s high-capacity nutrient control solution, specifically formulated for the biological reduction of nitrate (NO₃⁻) and phosphate (PO₄³⁻) in large and professional marine systems. Its advanced blend of organic carbon molecules and trace elements supports the growth of nutrient-reducing bacteria while maintaining a stable carbon-nitrogen-phosphorus (C:N:P) ratio—crucial for a healthy reef ecosystem.
Unlike chemical adsorbents, NO3:PO4-X allows for gradual, precise nutrient reduction without disrupting beneficial microfauna. It prevents nutrient imbalances that can cause zooxanthellae loss, UV shock, and coral decline. The 5000ml format is ideal for large-volume aquariums, public displays, coral propagation systems, and reef installations requiring continuous, long-term nutrient management.
Main features:
Gradually and safely reduces NO₃ and PO₄ biologically
Organic carbon blend stimulates denitrifying and phosphate-absorbing bacteria
Maintains a balanced C:N:P ratio for optimal system stability
Prevents zooxanthellae depletion and coral nutrient stress
Preserves microfauna and biodiversity in the aquarium
Suitable for SPS, LPS, soft corals, and sensitive invertebrates
Ideal as a carbon source for denitrators and biofilters
High-yield 5000ml format for long-term use in large marine systems
Recommended dosage:
Start with low daily dosing based on measured nutrient levels
Gradually increase to achieve target NO₃ and PO₄ values
Monitor frequently and adjust to maintain stable parameters
Why choose NO3:PO4-X 5000ml:
NO3:PO4-X 5000ml is the ultimate nutrient management tool for large and professional reef aquariums. With its scientifically balanced formula, it ensures consistent and safe nitrate and phosphate reduction, supports coral health, and maintains long-term biological stability—essential for successful marine system operation.
