Add the bleach, until you find your chlorine is staying TOO high.

Read the muriatic acid guide, linked in my signature, and then lower your pH to 7.6 or so.

I'm not seeing that you have a test kit: it's NOT option, IF you want your pool to run well. Once you're experienced, you won't use it much . . . but you are NOT there yet!
