Since my pool is public, I have to test (FC & PH) every 2 hours. TC once a day and Total Alkalinity once a week (i do this twice). CYA is not applicable since it is unstabilized indoor pool. I do Calcium Hardness test and calculate Saturation Index just because I know what it is, but it is not required. Everything is written down, so at the end of the week anybody who knows pool chemistry (like my maintenance superviser or city health inspector) can read it like a map of what was going on in my pool.
If you do the same for 3-4 days, you will have a very good idea of your pool's pulse. I noticed that on the days when nobody used the pool the PH raises faster. On days when I have more then 10 users it seem to slowly crawl up.
