Re: Bleach vs Chlorine Help.
Sodium hypochlorite is sodium hypochlorite whether it is labeled liquid bleach, liquid chlorine, or liquid shock. The only difference is the concentration and therefore how much you use. Laundry bleach is either 5.25% for regular or 6% for ultra and the pool store stuff is either 6%, 10% or 12.5%. Also be aware that the stronger the concentration the faster it loses strength. So that botttle of 10% or 12.5% you bought at the pool store might only be around 6-8% by the time it goes into your pool but that bottle of ultra bleach is probably going to be at 6% unless you've been storing it for a year in your garage.
