Continuum Reef Basis Strontium Dry 600g
Reef-Basis Strontium is a high purity strontium in dry form, designed to safely raise the strontium level in marine aquariums, providing essential strontium for aragonite formation and coral and other invertebrate growth. It contains no acetate, EDTA, polygluconates and is much stronger than many competitor's products because it is made from anhydrous salts, not hydrated salts.
