Essentials - SPS Reef - ATI

Built specifically for SPS-dominated reef aquariums, ATI Essentials SPS is a highly concentrated two-part dosing system that delivers alkalinity, calcium, and essential trace elements in carefully balanced ratios. Developed using data from tens of thousands of ATI ICP analyses, Essentials SPS helps maintain the stability and precision that demanding SPS corals require for exceptional growth, coloration, and long-term health.

Unlike many all-in-one dosing solutions, Essentials SPS utilizes inorganic alkalinity sources that are immediately available for coral calcification. Because these alkalinity components do not interact with nitrate or phosphate, hobbyists maintain complete control over nutrient management while still providing everything their corals need to thrive.

Each part contains a comprehensive blend of major, minor, and trace elements consumed daily within a thriving reef aquarium. By replenishing these elements in the proper proportions, ATI Essentials SPS helps prevent deficiencies, supports vibrant coloration, and promotes consistent skeletal growth without the need for multiple supplemental additives.

With approximately 3.6 times the concentration of traditional Balling-style two-part systems, ATI Essentials SPS reduces dosing volume while delivering exceptional value and performance.
