Easy solution to a complex problem

Often people dose basic solutions for basic items because this is the only thing they are testing for. The reality is unless you are doing frequent and expensive water changes or heavy dosing of many different items your reef is likely lacking many essential elements corals need to grow, have the best color and thrive. While you can certainly dose your reef’s needs in other ways, they are usually expensive, complicated and/or labor intensive.

Beyond the basics

In addition to the calcium, magnesium and carbonates provided in basic supplements, ATI Essentials contains 25 additional essential elements necessary for coral growth and coloration.

Usable straight from the bottle

Essentials Pro is a laboratory quality concentrate that can be diluted* or dosed directly from the bottle, giving you the flexibility to choose the dosing style that is right for your tank.


* Diluting Essentials Pro offers you more protection from accidental overdose caused by siphon or other issues.
