Hi,

A local grocery store has a sale on muriatic acid, $3 per gallon, which is quite a bit better than I've been paying.

Is there any reason I shouldn't "load up" at that price? Does muriatic acid have a shelf life?

And, same question for thier "Clorinating liquid", which apparently is just bleach at a higher concentration (sodium hypochlorite, I think?).

Thanks,
