| Reef Advantage Strontium
Reef Advantage Strontium™ restores and maintains strontium to levels
found in natural sea water. Strontium is utilized by corals in the
same manner as calcium and holds a similar importance in maintaining
a vigorous level of growth. It is most useful in densely populated
aquariums requiring a continuous supply of strontium. Reef Advantage Strontium™ is
a highly concentrated (30,000 ppm), ionically balanced strontium
supplement.
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.
