Once you get your test kit, you will be able to monitor it better. Also, after a while you will get to know your pool better as to how much UV is affecting it, rain, etc. and maybe test every 2nd or 3rd day.
Adding LC every day provides better consistency of maintaining your FC level at the desired level. Once you know your CYA then use the
FC/CYA Levels to target the range for your FC. Stay above the minimum and stay in the higher end of the range especially in summer with more UV, etc. trying to eat your FC.
As stated earlier, I add LC in morning and in afternoon. I usually try to have 8 hrs between additions (that is just my own timeline - nothing special about it). So if I get delayed in adding in the early morning and it becomes late morning, then I just wait at least 8 hrs or so.
Good Luck. If you have any questions on testing once you get your kit - come back and ask.
