Professional Support for SPS-Dominated Aquariums ATI® Essentials SPS is a highly concentrated, laboratory-grade two-part system engineered specifically for the demanding requirements of Small Polyp Stony (SPS) corals. Based on tens of thousands of ICP-OES laboratory analyses, this formula has been refined to provide optimal skeletal growth, accelerated metabolism, and the vivid, distinctive coloration that defines high-end SPS reef tanks. Unlike systems designed for general use, Essentials SPS utilizes a specialized inorganic alkalinity source to maximize pH stabilization, providing the high-pH environment that sensitive Acropora and other stony corals need to thrive. Key Benefits & Features Optimized for High pH: Uses purely inorganic KH components to stabilize the pH at a higher level, promoting faster calcification and coral health. Complete Elemental Profile: Supplies all major elements (Boron, Bromine, Calcium, Fluorine, Potassium, Alkalinity, Magnesium, Sulfur, Strontium) and essential trace elements (Cobalt, Iron, Iodine, Lithium, Manganese, Molybdenum, Nickel, Rubidium, Selenium, Vanadium, Zinc). 3.6x Concentration: Significantly more concentrated than classic Balling solutions, reducing the frequency of container swaps and saving space under the cabinet. Balanced Ion Chemistry: Precisely formulated to maintain a natural seawater balance and prevent "ion shift" over long-term use. Ready-to-Dose: No mixing or heating required; simply connect the bottles to your dosing pump. Component Breakdown #1 KH Complex Concentration: 10,000 °dKH per liter. Function: Maintains stable alkalinity and boosts pH. Added Essentials: Contains Fluorine, Sulfur, Iron, Iodine, and Selenium. #2 Calcium Complex Concentration: 74,000 mg Calcium per liter. Function: Replenishes calcium used during skeleton building. Added Essentials: Contains Magnesium, Strontium, Potassium, Boron, Bromine, and 9 essential trace metals. Dosage & Application For optimal stability, dose equal or very similar amounts of both solutions throughout the day. Guideline: 5–10 ml per 100 liters (26 gal) per day. Precision Tuning: Base your dosage on your tank’s measured daily consumption of alkalinity and calcium. Daily Consumption Dosage of #1 KH Dosage of #2 Calcium 0.5 °dKH 5 ml / 100L - 1.0 °dKH 10 ml / 100L - 2.5 mg/l Ca - 3.5 ml / 100L 5.0 mg/l Ca - 7.0 ml / 100L SPS vs. Mixed Reef: Which is right for you?

If crystals form in #1 KH Complex due to cold, gently heat to 45°C (115°F) or place on a radiator to re-dissolve. Dilution: If operating in cold environments, both solutions can be diluted 1:1 with RO water (ensure you double the daily dosage volume if you dilute).
