never ending source of kalkwasser, I think??

Tonight when I was at lowes browsing the isles for anything related to aquariums I strolled over to the gravel/sand section to see what they had. I found a 50 lb bag of "High Calcium Hydrated Lime". I'm not a chemist but isn't this kalkwasser, a bag was torn in a corner and it looked exactly the same. It was around 7 bucks for a 50 lb bag and something like that would last forever. Here is a link from a search I did with the above title. Hope this is it.

Hydrated Lime is the same as the same as pickling lime, hence kalkwasser. Not sure of the purity of the commercial stuff, but if you could find out where Ball gets theirs, it would probably track back to the same place. There can't be too many outfits making the stuff.
