ATI ICP Element Selenium - 150 mL
ATI ICP Element Selenium is a high-purity, single-element selenium solution for precisely adjusting selenium 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 selenium matters
- Oxidative stress: Selenium is part of the selenoproteins that protect coral tissue from oxidative stress under strong light.
- Light tolerance: When selenium is low, that protection weakens and corals tolerate high-output reef lighting less well.
- Cellular health: Supports long-term cellular health and metabolic efficiency.
Common causes of a deficiency (per ATI): salt mixes and generic trace blends that leave selenium out because so little is needed, plus natural consumption over time.
Dosing
- Contents: one bottle holds 7,500 µg of selenium
- Standard dose: 1 mL per 100 L (26 gal) raises selenium by 0.5 µg/L
- Safe daily limit: raise selenium by no more than 0.5 µg/L per day (1 mL per 100 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 selenium level.
How much should I dose? 1 mL per 100 L (26 gal) raises selenium by 0.5 µg/L. Do not raise it by more than 0.5 µg/L per day (1 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.
