ATI® Essentials SPS is a highly concentrated, two-part system for perfect growth, optimal metabolism, and pronounced, distinctive coloration in SPS-dominated reef aquariums. Based on our experience from tens of thousands of ICP lab analyses, the formula has been continuously optimized and refined over the years, providing you with a state-of-the-art, two-part system. Other features include:

• Provides all major elements: boron, bromine, calcium, fluorine, potassium, alkalinity, magnesium, sulfur, strontium
• Basic supply of the following essential trace elements without accumulation: cobalt, iron, iodine, lithium, manganese, molybdenum, nickel, rubidium, selenium, vanadium, zinc
• The purely inorganic component of KH stabilizes the pH value at a higher level, which is particularly desirable for sensitive SPS corals
• The concentrations are adjusted so that equal amounts of both solutions can be administered
• Individually adapted to the needs of your aquarium to achieve a natural water composition and avoid ionic imbalance
• Ready to use and approximately 3.6 times more concentrated than a classic two-part Balling. No more tedious preparation required.

ATI® Essentials SPS consists of the following two individual components:

#1 KH Complex

• Contains 27,000°dKH per 2,700 ml (0.71 gallon) bottle (10,000°dKH/l)
• Contains the trace elements iron, iodine, selenium
• Contains the main elements fluorine and sulfur
• Stabilizes the pH value
