Elements

Fuel your reef with precision

Supercharge coral growth

ATI Elements targets both major and trace elements to unlock faster growth and enhance coloration.

Proven results

From dedicated reef hobbyists to some of the largest coral farms in the world, reefkeepers trust ATI Elements to deliver consistent growth and vibrant coloration. With precision dosing backed by science, ATI helps push the limits of coral health and success at every scale.

ICP-compatible

Pair ATI Elements with ATI ICP testing for unmatched precision. Our ICP tests reveal exact trace element levels in your reef and provide clear dosing recommendations, making it simple to correct deficiencies and keep your corals thriving.

Small adjustments made easy

ATI Elements give you complete control to fine tune the amounts of trace minerals your aquarium needs. With these individual adjustments, you can achieve better results, giving your coral more growth and more vivid color. Every specific reef’s needs vary slightly depending on your coral choice and growth. ATI Labs and ATI Essentials ensure no coral goes without the elements it needs. By fine tuning your specific aquarium consumption, you can ensure every animal has plenty of the elements it desires.

High-purity ingredients

With formulations of individual elements made from the highest purity ingredients, you’ll have peace of mind when you dose your aquarium with ATI Elements.

Alkalinity

1 mL per 100 L/26.4 gal raises the value by 4 µg/L

Copper

Aids in enzyme processes and, in trace amounts, improves the metabolism and health of fish. 150 mL bottle

1 mL per 100 L/26.4 gal raises the value by 1 µg/L

Fluorine

Crucial to the coloration and skeletal strength of LPS and SPS corals. It is incorporated into coral skeletons as a calcium fluoride complex, producing strong, resilient coral structures. 1,000 mL bottle

10 mL per 100 L/26.4 gal raises the value by 0.2 mg/L

Iodine

Essential for the health of many soft corals and invertebrates. It helps invertebrates molt and contributes to overall immunity in reef environments. 1,000 mL bottle

1 mL per 100 L/26.4 gal raises the value by 10 µg/L

Iron

Benefits photosynthetic invertebrates and plants, providing nourishment for improved color and growth. 150 mL bottle

1 mL per 100 L/26.4 gal raises the value by 4 µg/L

Lithium

Supports enzyme activity and biological function in reef environments. 150 mL bottle

1 mL per 100 L/26.4 gal raises the value by 15 µg/L

Magnesium

Strengthens the skeleton of SPS corals and the tissue of soft corals. Proper magnesium levels prevent alkalinity and calcium from precipitating out of solution. 1,000 mL bottle

1 mL per 100 L/26.4 gal raises the value by 1 mg/L

Manganese

Essential for photosynthesis, coral coloration, and enzyme function. 150 mL bottle

1 mL per 100 L/26.4 gal raises the value by 4 µg/L

Molybdenum

1 mL per 100 L/26.4 gal raises the value by 6 µg/L

Nickel

Aids in enhancing enzyme function and improving metabolic activity. 150 mL bottle

1 mL per 100 L/26.4 gal raises the value by 3 µg/L

Potassium
