Your pool is cloudy because of algae. You need to do a proper slam. Buy a good test kit and a ton of liquid chlorine. You’ll need to raise your chlorine to slam level until the cloudiness goes away.
OK, is there a brand of liquid chlorine you recommend and/or one I should stay away from? I ask because I have never had this problem before and the only thing I have done differently this year is buy my pool products from a hardware store INSTEAD of at the pool store as I had always done before.
Also, I can't find the testing kit that bmoreswim recommends on Amazon. The TF-100 with XL option and the Speedstir is out of stock on Amazon.
Thanks!
