Essentials + from ATI is a revolutionary care system. Essentials+ supplies your aquarium with all the major elements (including KH, Ca and Mg) and helps keep them in the optimal concentration range at all times. Essentials+ also contains all essential trace elements (including iron, iodine, molybdenum, manganese, vanadium and zinc) and ensures their bioavailability in the aquarium.

With Essentials+, you replace 3 x 10 liters of conventional elements. All relevant elements are already premixed in the two Essentials+ bottles. The lab-grade concentrate can also be dosed immediately and does not need to be diluted.

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

By feeding your aquarium with Essentials+, you are able to balance typical reef dweller consumption with demand and consumption. In this way, the natural water values are permanently maintained, which is the cornerstone of any successful reef aquarium.

The production of our water care products is subject to strict control by our own laboratory. Quality assurance helps us select the purest raw materials and leads to a superior end product. With Essentials+ you get one of the purest products available for feeding reef aquariums on the market.
In general, Essentials+ #1 and #2 are consumed in equal measure. In this case, the dosage of Essentials+ #1 and #2 can be adjusted according to the KH consumption of your tank. If the calcium value changes over time, the dosage of Essentials+ #2 should be adjusted based on calcium intake.
