Essentials SPS #2 2700 ml – ATI

Professional Support for SPS-Dominated Aquariums

ATI® Essentials SPSis 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

Important Usage Notes

• Storage:Store above 20°C (68°F). 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).
