What is it
Sodium Hypochlorite is also commonly called liquid chlorine or bleach.
What else does it add
There is extra salt in the liquid chlorine due to the production process. 1 ppm chlorine added by sodium hypochlorite adds 1.64 ppm salt.
How to add
Bleach should be added to the pool by pouring slowly in front of a return jet with the pump running. You should pour slowly enough that pouring an entire jug takes more than one minute, preferably two minutes. Leave the pump running for at least 30 minutes after adding bleach.
