Looks ok to me. I'm no chemist though... @Randy Holmes-Farley

It is almost certainly fine, but does it specify a grade? ACS? FCC? USP?

I don't see any grade listed, but I expect it is fine. They are clearly testing it for certain impurities.

Thanks Randy, would you advise as others have suggested on using kalk on my sumpless nano rather than 2 part? I've got maxima clam, LPS corals x7 and a single SPS coral.
Many ways to skin a reef, this is mine. (54 Litre/14 Gallon)
