Reef Shot Calcium Many reef organisms synthesise calcium and strontium to form shells or skeleton from the seawater. Calcium Reef Shot is a quick and easy way to increase or maintain the optimum concentration of calcium in a reef aquarium. Levels of 400-450ppm are desirable to maintain a high level of coral growth. Instructions: Shake well before use. Add a vial (20ml) of Calcium Reef Shot per 200 litres (50 gallons) of water every other day. A weekly water change of 10-20% using Reef Evolution salt is highly recommended in order to maintain optimum water quality. When adding the product, pour gently into the current in order to obtain an even distribution. Allow 5 minutes between the additions of any other product. Do not mix different products together prior dosing. Direct contact with marine organisms should be avoided as a high local concentration may be harmful. Like all chemical products, it must be kept out of reach of children.
