ATI Essentials Plus 2 x 2700ml Set
Essentials+ is a revolutionary care system. Our experience from more than 40,000 seawater analyses has enabled us to further optimize the recipe of the successful Essentials. Essentials+ supplies your aquarium with all major elements (incl. KH, Ca and Mg) and helps to keep them in the optimal concentration range permanently. Essentials+ also contains all essential trace elements (including iron, iodine, molybdenum, manganese, vanadium and zinc) and ensures their bioavailability in the aquarium.
Cleverly combined, no more annoying mixing of elements. With Essentials+ you replace 3 x 10 liters of conventional element supply. All relevant elements are already premixed in the two Essentials+ bottles. The concentrate in laboratory quality can also be diluted directly into the aquarium water.

I’ve been using Essentials+ for over six months and it has made a noticeable difference in my tank’s water stability. No more worrying about trace elements or calcium drops. The mixing is simple and the results are consistent. My corals are thriving and the water parameters stay balanced.

The product arrived quickly and the instructions were clear. I replaced my old element mix with Essentials+ and found it much easier to maintain. The trace elements are well balanced and the water clarity has improved.
Anne Quinn –
After switching to Essentials+, my tank has had fewer fluctuations in pH and calcium levels. The two bottles are sufficient for a 100-gallon tank, and I no longer need to measure or mix individual elements.
