Calcium per instant 3000g bucket

In saltwater aquariums, large amounts of calcium and magnesium are needed to achieve optimal coral and red algae growth. 1 measuring spoon (approx. 10g) results in an increase in calcium content of approx. 18mg/l per 100 litres of aquarium water, without shifting the ion balance. In case of larger deviations, an increase should be made over several days. Insert directly into the filter basin, at a well flowed area. To maintain the calcium level in the aquarium permanently, the use of a calcium reactor is recommended. When using Calcium pro instant in the aquarium, the calcium content of the aquarium water should be checked regularly. Ideally this is 420mg/l
