Alright, so here's where I am this morning without having done any vacuuming or water change yet. I noticed my TA went down by 30ppm, is this a typical fluctuation due to buffering the system? Or if not, then one of my two test results (last night and this morning) is off. But That's OK, I'm going to go vacuum and top off now, and I will do another set of tests after that. I think maybe two hours of circulating after topping off should be good to do the test?
And, do I really even need to worry much about the Calcium Hardness Test? I have a vinyl lined above ground pool, and my current CH is 225ppm.
FC: 19ppm
CC: 1ppm
pH: 7.5
TA: 150ppm
CH: 225ppm
CYA: 50ppm
Thank you!!

Low Calcium in a vinyl pool is not a concern. High calcium can cause cloudy water.
