On the cap of my bottle of SeaChem's "Flourish" there is a sticker that
says to refrigerate after openning, which I did.  Well, I was wondering; Is
this really needed?  I haven't seen any comments on here about
refrigerating PMDD or any other trace elements or mineral mix?  What is it
(or in it) about Flourish that requires it to be refrigerated?
