One more question Watermom.

Do they also add stuff in "pool shock", or "liquid chlorine" that's not added to bleach? The reason i ask is we have a local farm store here called Atwoods, similar to Tractor Supply, and they carry chemicals for pools. I noticed their regular price on a gallon of pool shock was $2 and some change, which i thought was fairly reasonable, and instead of 6% or 8.25% it was 10% Sodium Hypochlorite. Is this basically just 10% bleach?? Don't want to be adding stuff that i don't need. They sell it by the case, which makes it easy. All the ingredients say is 10% Sodium Hypochlorite 90% inert ingredients.
