ATI Essentials

Essentials pro

Essentials pro is a revolutionary care system. Our experience from more than 20,000 seawater analyses has enabled us to further optimize the recipe of the successful Essentials. Essentials pro supplies your aquarium not only with all major elements (incl. KH, Ca and Mg), but also with all essential trace elements (e.g. iron, iodine, molybdenum, manganese, vanadium and zinc) and helps to keep them continuously in the optimal concentration range.


Cleverly combined, no more annoying mixing of elements

With Essentials pro you replace 3 x 10 liters of conventional element supply. All relevant elements are already premixed in the two Essentials pro bottles. The concentrate in laboratory quality can also be dosed immediately and does not have to be diluted.

Daily consumption

Your reef aquarium is a unique aquatic ecosystem containing many different organisms. All these organisms continuously extract substances from the aquarium water in order to be able to grow.

Daily consumption

By supplying your aquarium with Essentials pro you are able to balance the typical consumption of the reef inhabitants according to demand and consumption. In this way natural water values are continuously maintained, which is the cornerstone for every successful reef aquarium.

Only the best for your reef

The production of our water care products is subject to strict monitoring by our own laboratory. Quality assurance helps us to select the purest raw materials and leads to a top-quality end product. With Essentials pro you get one of the purest products available on the market for supplying reef aquariums.

Basics of dosing

Usually the essentials pro are consumed to the same extent. In this case, the dosage of Essentials pro 1 and 2 can be adjusted using the KH consumption of your tank. If the calcium value changes over time, the dosage of Essentials pro 2 should be adjusted based on the calcium consumption.
