Essentials - Mixed Reef - ATI

Simplify your reef dosing while providing everything your corals need to thrive. ATI Essentials Mixed Reef is a highly concentrated two-part system designed to maintain stable alkalinity, calcium, and trace element levels in mixed reef aquariums. Developed using data from thousands of ATI ICP analyses, Essentials Mixed Reef delivers a balanced supply of major and minor elements to support strong growth, vibrant coloration, and long-term reef stability.

Unlike traditional two-part systems, Essentials Mixed Reef incorporates both organic and inorganic alkalinity sources. The organic components can help support biological nutrient reduction, making it an excellent choice for aquariums with moderate to higher nutrient levels and mixed coral populations.

Each part contains a carefully balanced blend of major, minor, and trace elements that are consumed daily by corals and other reef inhabitants. By replacing these elements in the proper ratios, ATI Essentials helps eliminate deficiencies while reducing the need for multiple additives and complicated dosing schedules.

With approximately five times the concentration of many traditional two-part systems, ATI Essentials Mixed Reef delivers exceptional value while minimizing dosing volume and storage requirements.
