ATI Essentials pro 2000ml – #2 ONLY
ATI Essentials pro is a revolutionary care system. Our experience from more than 20,000 seawater analyses has enabled us to further optimise 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.
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.

I’ve been using Essentials pro for three months now and my tank has remained stable with no spikes in calcium or alkalinity. The setup was simple—just added the concentrate directly. My corals are thriving and the water parameters stay consistent.

It’s a big improvement over my previous element supplements. I no longer need to mix or measure multiple components. The trace elements are well balanced and the water clarity has improved noticeably.

After switching to Essentials pro, my tank’s stability increased significantly. I’ve reduced the frequency of water changes and the fish and invertebrates seem more active and healthy.
