CYA under 20
My pool was perfect until the rain came and working to many hours. I am working on my PH now. I have never used Dichlor before and read that it will also raise my CYA so I thought I would give it a shot. The charts are calling for 94 oz. My Question is as follows: Do I just add the 94 oz and let it go and retest in the morning or do I continue to shock with the Dichlor? Do I add the Dichlor then continue to shock with bleach? Also, I am aerating the pool now hoping for the ALK to drop some as I do have a fiberglass pool. Any help would be appreciated!!
