Red Sea NO3:PO4‑X is a controllable, reef‑safe nutrient control additive designed to help manage and reduce nitrates (NO₃) and phosphates (PO₄) in marine and reef aquariums. It contains a unique complex of carbon sources and organic‑bound elements that stimulate natural nutrient‑reducing bacteria already present in your system. These bacteria use the carbon compounds to convert nitrate into nitrogen gas and absorb phosphate, helping to lower the levels of these nutrients — which are primary food sources for nuisance algae — in a safe and gradual way. By carefully dosing NO3:PO4‑X with regular testing, you can achieve accurate control of nitrate and phosphate levels, reducing unwanted algal growth while still maintaining healthy populations of beneficial microorganisms and symbiotic zooxanthellae algae in corals. This promotes better coral growth, improved colouration, and overall reef vitality without harsh chemical removers. The product is reef safe, easy to use, and designed for daily dosing, making it effective for both newly established and mature reef systems when used alongside good protein skimming and regular monitoring.
