Magnesium Test

Testing magnesium in a reef aquarium is vital for maintaining a stable environment, as magnesium plays a key role in balancing calcium and alkalinity levels. Proper magnesium levels, typically between 1250 to 1350 ppm, prevent calcium and carbonate ions from binding and precipitating out of solution, supporting coral growth and overall tank stability. To test magnesium, use a test kit that involves adding reagents to a water sample and observing a color change to determine concentration. Regular testing and adjustments, if needed, help maintain a balanced, healthy environment for corals and other reef inhabitants.
