Many reef organisms synthesise calcium and strontium to form shells or skeleton from the seawater. Strontium Reef Shot is a quick and easy way to increase or maintain the optimum concentration of strontium in a reef aquarium; an essential role in calcification. Levels between 5-15ppm are advisable to maintain a healthy environment for your corals. 

Instructions : Shake well before use. Add a vial (20ml) of Strontium Reef Shot per 200 litres (50 gallons) of water every week. A weekly change of 10-20% of the water using Reef Evolution salt is highly recommended in order to maintain optimum water quality. When adding the product, pour gently to the current in order to obtain 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 high local concentration may be harmful. Like all chemical products, it must be kept out of reach of children.
