Red Sea NO3:PO4-X is an advanced carbon-based supplement designed to reduce nitrate and phosphate levels in reef aquariums. By supporting beneficial bacteria, it enables controlled nutrient reduction, helping to maintain clear water and promote healthy coral growth and colouration.

Key Features:

• Carbon complex for controlled nitrate and phosphate reduction
• Supports growth of nutrient-reducing bacteria
• Helps prevent nuisance algae development
• Maintains balanced nutrient levels for coral health
• Protects zooxanthellae to support coral colour and stability
• Encourages complete nitrate reduction to nitrogen gas
• Aids phosphate uptake and utilisation by bacteria
• Suitable for reef aquariums and carbon-based filtration systems

The formula contains a blend of carbon sources used by different strains of microorganisms, allowing for efficient nutrient processing at each stage. Additional elements within the mix help sustain bacterial activity, ensuring consistent and gradual nutrient reduction without sudden changes.

With careful and monitored dosing, NO3:PO4-X allows for precise control of nutrient levels, avoiding stress to corals while maintaining the beneficial microfauna within the system.

A reliable solution for nutrient management, Red Sea NO3:PO4-X helps maintain a stable, low-nutrient environment that supports coral growth and colour.
