I’m kind of in the middle ground on this. I don’t test daily, but I don’t just wait a whole week either. What’s worked for me is setting a “baseline” check once a week with the drop kit, then slipping in a couple of quick strip tests mid-week. That way, I know if chlorine or pH is drifting before it becomes a headache.
If the pool’s getting heavy use or we’ve had a storm, I’ll usually test right after since those seem to throw things off the most. In the cooler months, though, once a week is plenty, sometimes even every 10 days if the pool is just sitting there.
I’m curious, for those who test daily in summer, do you find the readings change that much from one day to the next? Or is it more peace of mind than actual necessity?
