Fritz Elements Calcium

Fritz RPM Calcium Buffer System Part 2 delivers highly concentrated liquid calcium to maintain the critical mineral balance your reef requires. This pure calcium formula works alongside Part 1 to restore proper ionic equilibrium without introducing unnecessary trace elements that can accumulate to toxic levels. Each millilitre raises calcium by 15 ppm per gallon, making it ideal for manual dosing or automated systems. Simply dose equal parts of Part 1 and Part 2 daily to keep calcium levels between 400–450 ppm, supporting vibrant coral growth and healthy invertebrates. Compatible with all Fritz products and equipment-free to use.
