I don't know of the metallic properties of strontium, but it is a natural trace element found in seawater. If kept at NSW
levels it is benificial to LPS
corals, it was almost impossible to keep Elegance corals before addition of strontium became common place (now it is impossible cause of Gall Crabs
), it aids in the prevention of tissue sloughing from the skeleton. I do not add anything to my reef that I don't test for, I keep softies, LPS
. If you do frequent waterchanges, I d not feel it is necessary to replenish trace elements, Major elements like CA
and Carbonate are another story....
