Hello everyone, I'm new here and I'm trying to do this pool chemical stuff without the costly help of our local costly pool stores and there high priced chemicals. I had every thing going well until last week when here in Tennessee it rained almost daily for a week now my pool is turning green again. I really need some help with where to start. I am using a Taylor test kit k-2006. My results are showing: no free chlorine
Im hoping to stop this green before it gets out of hand.
