Walmart has bags of hth super sock it calc hypochlorite that states available chlorine is 53%/CaHypo is 54.6%.

Does this one bag of shock equal 10 gallons of 5% bleach?

If not, then what part of this equation am i not understanding?

I have been reading the forum for several days, and now I don't know what to buy. I stood there with a shopping cart full of 12 1.5 gallons of bleach, and wasn't sure if I should just get the shock instead.
