If you don't get some chlorine in there, you're gonna have an additional problem to deal with......... a green pool!

Tonight, add a couple of quarts of bleach in there.

What is your pH? Do you have a kit?

Don't add anything else right now but bleach and if your pH is lower than 7.2, add some 20 Mule Team Borax. You don't want your pH to go lower than 7.0 or it can damage your pool.
