One of the companies I usually buy from for pool shock will regularly have shock for $2.50 per lb and free shipping during pool season. Not much cheaper than this deal but every bit helps

For Reference 1 lb of cal hypo 53% raises your ppm by 6.5 in a 10,000 gallon pool.

Safe, yes. Desirable, no! Overtime you will calcify your chlorinator.
