This highly concentrated two part dosing system is designed specifically for saltwater aquariums dominated by small polyp stony corals. It delivers a balanced supply of major elements and trace nutrients to support coral growth and coloration without the need for additional additives. The formula ensures inorganic alkalinity remains immediately available for coral uptake while maintaining stable nutrient levels within the display tank.
Each set includes two bottles totaling 5.4 liters of solution that are approximately 3.6 times more concentrated than most standard two part systems. The formulation is built on data from tens of thousands of ICP lab tests to provide optimized levels of calcium, magnesium, strontium, iodine, iron, potassium, and other trace elements. Users should note that Part 1 may precipitate out of solution and requires warming in a hot water bath to return it to liquid form before use.
This supplement set is ideal for aquarists managing tanks with low to moderate fish loads who desire complete control over their nutrient parameters. It helps increase and stabilize pH while preventing the harmful accumulation of elements often associated with less precise dosing methods. Reef keepers seeking long term health, vibrant coloration, and strong growth for their SPS corals will find this comprehensive solution essential for maintaining water chemistry balance.
