ATI ICP Element Calcium - 1000 mL
ATI ICP Element Calcium is a high-purity, single-element calcium solution for precisely adjusting calcium levels in reef aquariums. It is part of ATI's revised ICP Elements line, developed and tested in the ATI Lab in Germany, and ATI designs it both for correcting an acute deficiency and for maintaining the daily supply. Pair it with an ATI ICP-OES water analysis to see exactly what your water needs, and browse the rest of our reef supplements.
Why calcium matters
- Skeletal integrity: Calcium is a primary building block for stony corals and coralline algae; low levels lead to soft or deformed skeletons in LPS and SPS.
- Coral vitality: A deficiency often shows as poor polyp extension and pale color.
- Growth: Too little calcium noticeably slows the growth of fast-growing reef animals.
Common causes of a deficiency (per ATI): high demand in mature SPS and LPS systems, too little daily dosing, or equipment problems such as a failed dosing pump or a clogged line.
Dosing
- Contents: one bottle holds 200,000 mg of calcium
- Standard dose: 1 mL per 100 L (26 gal) raises calcium by 2 mg/L

Frequently Asked Questions
Do I need an ICP test to use it? ATI built the ICP Elements for precise adjustment, so dose against a measured value. An ICP analysis such as the ATI ICP-OES Pro Water Analysis tells you your current calcium level.
How much should I dose? 1 mL per 100 L (26 gal) raises calcium by 2 mg/L. Do not raise it by more than 40 mg/L per day (20 mL per 100 L).
Can I use it for daily maintenance? Yes. ATI states the ICP Elements are suited both to correcting acute deficiencies and to maintaining the daily supply.
