Just got a new pool put in and I am new to pools. So I don't know much about them. The pool people didn't do the prep work properly. Had a very hard rain and washed some sand in the pool, and the water is kind of a green tinge. Talked to them was told to shock it, which I did. Thinking now that that was a mistake. I'll do water test tonight and see what the levels are. Wish I found this site last night instead of today before I shocked it. Looking for some help. Thanks
