"Hydrated Lime" vs "Pickling Lime or Quick Lime"

So after searching at every local establishment that generates income from selling products to customers, I found something at Ace Hardware. It was in the garden department and is used to sweeten soil. It was labeled "Hydrated Lime".
Calcium (CA)...........................................51.50%
Calcium Oxide (CaO).................................72.50%
Magnesium Oxide (MgO).............................0.45%
Calcium Carbonate Equivalent (CaCO)...........131.00%
Calcium Hydroxide (Ca(OH)2).......................95.79%
ENP...........................................................130.35%
ENV.........................................................130.35%
It was an EXTREMELY fine powder. At least as fine as baby powder. Came in a plastic zip-lock top bag. Like 5lbs for $8.

After searching around the net, I have found a couple places that seem to hint that it's the same stuff as pickling or quicklime, but with added water.

Can I use this stuff? It's local and cheap as all hell.

Try the Reef Chemisty Forum. Randy would be the best person to ask.
