Testing pattern?

When you test, say pH and FC, and decide you need to add something to the pool, do you test-add-retest (same day, but after a period of time) or do you test-add and wait until your next regular testing time (for me, that’s the next morning)?

Mainly asking for when adding MA and LC, that change the pool chemistry in short order, rather than something like CYA which takes longer to achieve its effect.

Once you know your pool, you add based on your testing. Then move on to the next time.

With a SWCG, and knowing my pool, I test about twice a week, just for data purposes. You get to where you can look at your pool water and know it has an issue.
