Magnesium Supplement for Reef Aquariums: Growth, Balance and Stability

Magnesium plays an absolutely central role in seawater chemistry. Too often overlooked, its level directly impacts the stability of alkalinity and calcium . If magnesium drops, these last two elements can precipitate, making their absorption by corals much more difficult. The result: slowed growth, a weakened skeleton, degenerated soft corals and even the absence of coralline algae on live rocks. In short, a silent but formidable imbalance.

The ATI Labs Magnesium solution helps to address this deficiency in a controlled manner. Each milliliter increases the magnesium concentration by 1 mg/l per 100 liters of water . It is recommended not to exceed 100 mg/l increase per day , or 100 ml per 100 liters, to avoid sudden variations. The generous 1000 ml bottle allows for correction over several weeks or even months depending on the tank's needs.

Whether it's to compensate for high consumption by calcifying corals (especially SPS and coralline algae), or to correct an imbalance caused by too little salt, this solution does the job perfectly. And like all products in the ATI ICP Elements range, it benefits from color-coded identification according to the level of mastery: perfect for those who want to dose without making a mistake.

Finally, its development strictly follows the European CLP regulation (EC No. 1272/2008) and it is registered with ECHA, which guarantees maximum safety for fauna, flora and the environment . Real peace of mind for all reefers who only want the best.
