Works Great Despite the Clorox Name Throwing Me Off
I was a little skeptical at first because when I hear “Clorox,” pool chemicals definitely aren’t the first thing that comes to mind. However, this pH increaser worked great and was easy to use. It raised my pool’s pH as expected and helped get the water balanced without any issues. The instructions were straightforward, it dissolved well, and my water felt more comfortable afterward. Turns out Clorox knows more than just bleach—this one did exactly what I needed it to do.
