Waterbox Magnesium Reef Supplement – 500 ml

Waterbox Magnesium is a liquid supplement for maintaining magnesium in reef aquariums. Keeping magnesium at the correct level helps corals and other reef inhabitants take up calcium and alkalinity, which supports their growth and overall health. Waterbox recommends a range of 1200 to 1400, and each 5 ml dose raises magnesium by 3.75 mg/l in 100 litres (25 gallons) of water.
