What to use for clorine

[Technics19]

Was just at Walmart, this is in Saskatchewan Canada and could buy:
4L HTH liquid shock ( sodium hypochlorite 10.8% available clorine content 10.3% it had no other useful info than that) for $5.47 plus tax
or
3.57L Clorox original concentrated bleach ( doesn't give any info, it says go to The Clorox Company | Products | Ingredients Inside and I couldn't find the exact bottle there to see sodium hypochlorite % one I looked at said 5-10%) for 4.33 plus tax.

does anyone know if the HTH liquid shock contains any other stuff that I don't want in my pool.
For now I grabbed 4 bottles of Clorox

Go with the HTH liquid shock. It's 10% good stuff.

Someone recently posted that the "concentrated" bleach in CA is 6%

You might want to check around closer to home. They use high-strength Sodium Hypochlorite ( bleach) to sanitize dairy equipment. You may discover the farm supply store has it at a good price.
