Question: what is the difference between sodium hypochlorite and bleach?
Answer: Sodium Hypochlorite is a liquid Chlorine and has around 10-12% available Chlorine. Available Chlorine (AC) is the amount of Chlorine released in the water to disinfect. Bleach, which contains Sodium Hypo, only has 5% AC which is why bleach is not a good pool disinfectant.
