I bought a box of Chlorox Shock Plus, active ingredient Sodium dichlor
(like this: Clorox Pool and Spa Shock Plus, 12-Pack - Walmart.com)
And I just finished using it for my pool opening which was battling massive algae, when I looked at the box and it said:
"Not for use as a sanitizer or algaecide."
I am waiting on a refill kit to test my other chemicals, but it indeed was adding chlorine (along with stabilizer I think so I'm switching to bleach as soon as I can). So what does that mean? Why would it say it's not a sanitizer
