The Aquaforest TestPro Pack includes drop tests to check levels of Ca, KH, and Mg in saltwater aquariums. Calcium, Alkalinity, and Magnesium are the most crucial parameters in a reef aquarium and should be monitored regularly. To ensure the proper functioning of the marine aquarium calcium levels should be maintained in the range 380-460 mg/l (ppm), Magnesium should fall between 1260-1460 mg/l (ppm), and alkalinity should vary between 6.5-8.0 dKH for Ultra Low Nutrient Systems (ULNS) or higher for aquariums with more nutrients.
