Strontium occurs in natural seawater at a concentration of about 8 to 10 mg/L. It is chemically very similar to calcium, and many organisms incorporate it in their skeletons along with calcium. Its addition to reef aquariums aids the growth of corals, coralline algae and other organisms that lay down a calcereous skeleton or shell, including tridacnid clams. Sizes: 70 g, 300 g, 600 g, 1.2 kg, 4 kg, 20 kg Why It's Different Unlike other strontium chloride products, Reef Advantage Strontium™ is formulated so that it can be added directly to the aquarium. Competing products require one to mix a separate solution before adding it to the system. Directions BEGINNER: Use 8 g (1 level teaspoon*) per 150 L (40 gallons*) twice a week. May be added directly to aquarium. DO NOT OVERDOSE: Excess strontium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if strontium & carbonate additives are added on alternate days or at least 30 minutes apart. |
