Thanks,
I had a large bottle of 30% reagent grade years ago but finally disposed of it for lack of use. Got it with a bunch of other chemicals form a chemical milling outfit that was being liquidated.
I just looked at the Leslie's Pool Supplies web site, they have it listed under Pool chemicals > Chlorine Alternatives Baquacil Shock and Oxidizer item 13319 for $17.99 per gal. (actual name appears to be Baquacil Oxidizer) The MSDS lists the concentraton at 27.5%
