The Red Sea NO3: PO4-X is a specialized solution designed to reduce nitrate and phosphate levels in saltwater reef aquariums. This unique complex of carbons supports the growth of nutrient-reducing bacteria, ensuring that each stage of bacterial propagation maintains optimal Carbon:Nitrogen:Phosphorus ratios for efficient nitrate reduction and phosphate absorption. The product includes organic-bonded elements crucial for stimulating microbial activity at different stages of the nitrogen cycle, leading to complete conversion of nitrates into harmless nitrogen gas and effective uptake of phosphates by bacteria. It is recommended for use with carbon-based denitrators and provides a precise dosing method through its included measuring cup.
