Calcium is one of the pillars of ionic balance in a reef aquarium. Without sufficient calcium, the growth of hard corals slows considerably, their skeletons become soft or deformed , and their colors fade. Coralline algae, also major consumers of calcium, can disappear, leaving a depleted and unstable tank.
The ATI ICP Element Calcium solution meets these needs precisely. Its simple and effective dosage: 1 ml per 100 liters increases the concentration by 2 mg/l . To maintain the stability of the tank, it is recommended not to exceed 40 mg/l per day , or 20 ml per 100 liters . Thanks to its high concentration, each bottle offers long-lasting use, whether for occasional correction or daily supplementation .
The causes of calcium deficiency are multiple: high consumption by fast-growing SPS and LPS , dosage errors in two-component methods or even dosing pump failures. With the ATI Labs solution, these problems find a reliable and secure solution, always compliant with the standards of the European Chemicals Agency (ECHA) and the CLP regulation (EC n°1272/2008).
Integrated into the ATI ICP Elements range, this solution benefits from a color-coded system to easily identify its use according to your level: beginner, advanced or expert. An essential tool for anyone who wants to keep a vibrant and healthy reef.
