Hi I’m a second season pool owner (not salt water). This year I have been consistently measuring 7.0 to 7.2 pH and adjusting to try to get it closer to 7.4-7.6 range. My CYA is consistently 80 using liquid chlorine to shock and 99/1% pucks. I kept my chlorine according to the chart on this site. I’ve been thinking about shifting away from the pucks by using liquid chlorine in a daily basis. My pool and filter are old and I’m not considering adding an in-line chlorine system at this time. This weekend I was in the pool and and really felt some eye and throat irritation which I hadn’t experienced before.
So I checked TA and it was 50. Using pool math app I increased it to 60, which was confirmed on my test kit, and pH up to 7.2. CYA however seems to have spiked to 100. Could that CYA spike be a result of increasing the TA? It’s also been raining a lot this year in Massachusetts so I’m wondering if that has been keeping the pH low?
My basic point is the pool has been clean and decent without complaints until this weekend and I don’t want to screw up my routine and get into a cycle of chasing levels in any chemical. So basically again could the TA increase have contributed to a CYA spike? My thought is no but I’d appreciate any input. Thanks in advance.
