The Reef Blueprint Isol8:Ca Calcium Solution is a high-quality calcium supplement designed to maintain optimal calcium levels in marine aquariums and reef tanks. This product contains anhydrous calcium chloride, which effectively increases the concentration of calcium ions in water by up to 1.50 ppm per milliliter added to your tank. It's crucial for maintaining stable water conditions that support healthy coral growth and other calcium-requiring organisms in saltwater environments. Daily monitoring and dosing adjustments based on system requirements are recommended to achieve ideal calcium levels.
