Coral Essentials Coral Power Nitrate Up is a concentrated, inorganic nitrogen source. In bacteria-driven systems, it provides an essential nutrient source to assist with biological stability in Marine Aquariums. Increasing the Nitrate value allows the bacteria present to naturally bring down phosphate levels, whilst providing a food source for your corals.
In ULNS (Ultra Low Nutrient Systems) aquariums corals can become pale and unhealthy if they are starved of available nitrate. Coral Essentials recommends using Coral Power Nitrate Up when your system is too efficient at removing nitrate. Coral will be more vibrant and colourful when nitrate and phosphate are maintained at the correct levels.
