Yeggim - The water is crystal clear. I have very good news. My CL levels held very steady over night. Last night, CL=9. This morning it looks like 8 or 9. I feel much better than yesterday with regards to the pool. I was very worried the pool had an ammonia problem. As I said, that test came back negative. My CYA - is unknown due to the fact that I ran out of r0013. The strips have been showing a wide range so I'm sticking with my last "known" CYA of 70. So what is my target now with regards to the CL levels? Thank you for your help. One more thing, I would like to make a donation to the site. How can I do this?
