TEST MG-CA – JBL Magnesium and Calcium Test Kit for Marine Aquariums, Optimal Coral and Algae Growth
The JBL TEST MG-CA kit offers a reliable and accurate method for measuring magnesium and calcium levels in marine aquariums. These two macroelements are essential for the healthy growth of hard corals and red calcareous algae and are key components of total water hardness. Low magnesium or calcium levels can hinder skeletal growth and cause imbalances in reef systems, making regular monitoring essential.
The test procedure is straightforward: first measure calcium, then magnesium. Subtract the calcium result from the magnesium result to determine the actual magnesium concentration. JBL has updated the test protocol to account for modern artificial sea salt mixes by recommending a multiplication factor of 120 (instead of 100), ensuring precise results adapted to today’s aquarium needs.
Suitable for both beginners and experienced reefkeepers, the test kit comes with easy-to-follow instructions and can be used in conjunction with the JBL Online Lab, which offers personalized water analysis and recommendations. The number of tests depends on the actual calcium and magnesium concentrations. Refill reagents are available separately for long-term use.
