Coral Power Nitrate Up
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 correct levels. Coral Essentials recommends running your aquarium at a nitrate level between 1ppm and 5ppm.
