So, this whole season I have had nothing but 8.0 or above for PH (usually I have to adjust to get it above 7.4). My calcium hardness has stayed about 200-220. Alkalinity is 110. And then there is my dreaded CYA. Drained a bit twice to get it to 40 and stay in the range.. until now. Filled test tube and I can still see dot at 30. I want to close my AG pool this week. Am I safe to try and close to SLAM at what it’s saying is 12 for FC? I’m worried about the calcium hardness and CYA. Don’t want to have to drain pool right before close. Please help.
Thank you
