NO3:PO4-X 1000ml – Biological Nitrate and Phosphate Reducer for Large Reef Aquariums
NO3:PO4-X 1000ml is Red Sea’s professional-grade nutrient reducer designed for safe and natural nitrate (NO₃⁻) and phosphate (PO₄³⁻) reduction in large marine and reef aquariums. Its unique formula contains a precise blend of organic carbon molecules and essential trace elements that selectively promote the growth of nitrate- and phosphate-reducing bacteria.
This process naturally balances the carbon, nitrogen, and phosphorus (C:N:P) ratio, enabling gradual nutrient reduction without sudden parameter shifts that could harm corals and disrupt the aquarium’s microbiome. Unlike chemical adsorbents, NO3:PO4-X supports and preserves beneficial microfauna and promotes long-term biological stability.
Perfect for daily use in high-demand reef systems, the 1000ml format is ideal for large aquariums and continuous dosing. It also serves as a complete carbon source for denitrators and advanced biological filtration systems.
Main features:
Gradual, biological reduction of nitrates and phosphates
Organic carbon complex with trace elements for microbial efficiency
Maintains ideal C:N:P ratio for balanced nutrient control
Prevents zooxanthellae loss and coral starvation
Preserves beneficial microfauna and microbiome stability
Safe for SPS, LPS, soft corals, invertebrates, and reef systems
Ideal as a carbon source for denitrators and biofilters
Large 1000ml format suitable for big tanks and long-term use
Recommended dosage:
Start with a low daily dose based on NO₃ and PO₄ test results
Gradually increase until desired nutrient levels are achieved
Monitor regularly and adjust dosage for maintenance
Why choose NO3:PO4-X 1000ml:
NO3:PO4-X 1000ml is the ultimate solution for advanced nutrient control in large reef tanks. It offers precise, natural management of nitrates and phosphates, supports coral health, prevents algae outbreaks, and maintains microbial balance—an essential tool for professional reef aquarium care.
