Safe to swim right after it rains?

I have been working on my getting my chlorine levels up, this morning added a gallon of chlorine and Acid.
We had a quick rainfall about an hour ago but it passed quickly. The kids want to swim, is that generally ok or do I need to test or do anything or can I just add more chlorine tomorrow like I had planned to keep the levels up. Thanks!

If you are mixing with the pump running, rain can only dillute you by by the % of rainfall in relationship to your average depth. 1 inch of rain in 60 inches (5 ft average depth, maybe more) is a 1.6% loss across your tests and unnoticeable. The problem lies if you let cold 0 FC rain water sit on top for 12+ hours until the pump kicks on its next cycle. It's still 'safe', but you run the risk of leaving the door open for algae.

Ok makes sense. So we will run pump and swim and add chlorine tomorrow as usual. It wasn’t even an inch of rain...

We swim before, during and after rains. There’s absolutely no issue.

As long as there is no threat of lightning.

Well, if you live in an area where acid rain is common, you'll want to keep your eye on the pH. Maybe you'll get to save money on MA.

Bonus points if you guys are the mixers.

Oh YES - of course. Texas rain is either a raging awful thunderstorm or gentle all-day rain. The good news is the thunderstorm is usually in and out in 20 minutes!
