There are things that change rapidly like FC and pH and things that change slowly or due to specific events like CYA, TA, and CH. I test FC and pH every other day and the other things once a month or sooner if something is going on.
I will push FC to the top of the range and then I let it fall to the bottom of the range by adding bleach only every other day. Sometimes that bites me back and I have dull water or, yikes, FC of 0 to deal with. I am really tired of bleach splashed clothes so I dread the adding of bleach. Now that there are teens next door I can't just strip to my undies the way I used to when I had to add bleach.
pH is tested every other day and when it gets to 7.9 I drop it to 7.4 (or even 7.2 if TA is getting too high).
I keep CYA and CH and TA in their recommended ranges, trying for whatever end of the middle is most advantageous. That is, for my pool, CH falls due to winter rains and only goes up if I use cal-hypo for chlorine -- so middle of the range is best, when it gets low I use cal-hypo for FC needs to slowly boost it. In my pool, TA goes up a lot when I use fill water and goes down with winter rains or if I am using trichlor tablets during vacations. I keep it at the bottom of the range with some room to spare when I am planning a trip. In my pool, CYA drops over winter either a little (passage of time) or a lot (massive rains) and only goes up when I use trichlor tablets for vacations. Each week out of town will add 10 ppm to CYA so I tend to try to keep it low, inspite of needing it a bit higher for TX sun, just for the vacation effect. (Retired so rather a lot of traveling at this point.)
