ATI Essentials SPS - 5.4 Liter Set

Comprehensive Dosing for SPS Dominant Systems

• Alkalinity & Calcium Dosing with Trace Element Support
• About 3.6X More Concentrated Than Most Two-Part Systems
• Increases and Stabilizes pH
• Ideal for Tanks with Low to Moderate Fish Loads

ATI Essentials SPS is a highly concentrated two-part dosing system designed for SPS dominant aquariums. Built on data from tens of thousands of ICP lab tests, this formula delivers a balanced supply of both major and trace elements.

Note: Part #1 can precipitate out of solution. To get it back into solution, we place the bottle in a hot water bath to heat it up.

Comprehensive Dosing: Go beyond calcium and alkalinity by supplying a full spectrum of trace elements, like iodine, iron, molybdenum, vanadium, and more—at optimized levels built on tens of thousands of ATI ICP tests. Each formula is engineered to deliver precise coverage without the risk of harmful accumulation, helping corals achieve vibrant coloration, strong growth, and long-term health without the need for additional additives.

Inorganic Alkalinity: Inorganic alkalinity is immediately available for coral growth as bicarbonate and carbonate. Unlike the organic form, it does not interact with nitrate or phosphate, so nutrient levels remain stable. Ideal for aquariums where the user desires complete control over the nutrient levels in the tank.

Highly Concentrated: Each 2,700ml bottle delivers 27,000 °dKH of alkalinity and 200,000 mg of calcium, making it one of the most concentrated dosing systems available. Approximately 3.6 times more concentrated than traditional Balling two-part systems. Essentials SPS can be diluted with RO/DI water, if desired.
