Keep hitting it with bleach. Any idea what your CYA level is? We need that to be able to advise you how high to take your chlorine. Run your pump 24/7 while you are working to clear it. Backwash pump as needed.

If you don't have a good kt, get one. We recommend the Taylor K-2006 or 2006C which is the same kit with larger quantities of some of the reagents. You can get it through the Amazon link in my signature. Make sure the seller is Amato Industries; some other sellers are substituting the K-2005 instead and you don't want that one.

I'd like to welcome you to the Pool Forum!
