ATI Labs - Chrome is an ultra-pure solution specially formulated to correct chromium deficiencies and maintain optimal biological balance in reef aquariums. 100% manufactured and controlled in Germany, this solution complies with the strict standards of ECHA and the CLP regulation (EC No. 1272/2008) . Although the symptoms of chromium deficiency are still poorly documented, its role remains important for enzymatic function and micronutrient availability in bacterial biofilms. Each 150 ml bottle contains 15,000 µg of pure chromium , allowing simple, accurate and safe dosing, both for daily supplementation and for adjustment after ICP analysis.

Chromium is a discreet trace element, but it likely plays a key role in enzyme regulation and micronutrient availability within biofilms. In a closed reef, its absence can limit certain biological responses, particularly in invertebrates and bacterial communities. Although no clear symptoms have been identified, maintaining stable levels contributes to a balanced ecosystem and the overall health of the tank.
The ATI ICP Element Chrome solution is calibrated for precise management: 1 ml per 100 L = +1 µg/L . To avoid excess, it is recommended not to exceed 0.5 µg/L per day (0.5 ml per 100 L). This extremely precise dosage makes it possible to secure intakes and maintain perfect control of the concentration. The 150 ml bottle thus offers a long-term reserve for occasional corrections or regular supplementation .
Chromium deficiencies often stem from naturally low sea salt , a lack of compensation through trace element solutions, or constant removal by the skimmer when chromium is bound to biomolecules. ATI Labs makes it easy to compensate for these losses and ensure the continuity of biological processes.
As with the rest of the ATI ICP Elements range, this supplement benefits from a color-coded system to guide the user according to their level: beginner, advanced or expert. A modern and accessible approach that simplifies maintenance while offering laboratory precision.
FAUNA MARIN Balling Salt Magnesium Mix 1kg is a special ultra-pure salt for magnesium supplementation in marine aquariums using the Balling Light method.

Easy to use and compatible with all filtration systems, it ensures stable water and a consistent pH for a healthy and thriving aquarium.
Reef Iodide™ is a stabilized source of concentrated potassium iodide (8,000 mg/L) for reef aquariums that will restore and maintain iodide levels to those present in natural seawater . It is formulated to provide a safe source of iodide that will not be converted to toxic free iodine.
ATI Labs - Vanadium 150 ml is a highly purified solution designed to restore and maintain optimal vanadium levels in reef aquariums. Although often overlooked, this trace element plays an important role in coral coloration and sponge development . Deficiencies may go unnoticed, but their effects are very real: dull hues, slowed growth, less active sponges... Thanks to its concentrated formula from ATI laboratories in Germany, each milliliter allows for precise and controlled correction, in complete safety. Perfect for those who want to push precision even further with the support of an ICP analysis.
Simple, fast and precise , the ICP analysis of Fauna marin will allow you to know with precision the value of the main macro-elements and trace elements of the water of your marine aquarium.
Cobalt is one of those trace elements that is rarely discussed, but which makes all the difference in a well-balanced reef aquarium. With ATI Labs Cobalt 150 ml , your corals will regain striking color intensity, healthy growth and increased vitality.

ATI Labs - Selenium 150 ml is an ultra-pure solution designed to restore selenium balance in reef aquariums. Even in very small amounts, this trace element is crucial for the health of corals, especially those exposed to high light intensity . Indeed, selenium is involved in the production of certain protective proteins that act as natural antioxidants. When it is lacking, corals become more susceptible to oxidative stress, which can lead to general weakening. Thanks to its precise dosage and its formulation from the German ATI laboratories, this supplement allows for reliable and safe adjustment of selenium, while being compatible with ICP analyses.
