We saw some slight Algae because of the crazy heat we are getting in PA recently, I shocked the pool with 2lbs of shock last night at about 10pm, 22,000 gallon pool. When is it okay to swim? I just took these results from a test.

It is safe to swim if you can see the bottom, and your FC is between min and slam level FC for your CYA. Link-->FC/CYA Levels

Heat does not cause algae, lack of clorination allows algae to form. Always keep your FC in range for your CYA. See link above.

If you have visible algae, time to follow the SLAM process. Link-->SLAM Process

It is safe to swim so long as fc is between min & slam level for your cya, ph is in the 7’s, & you can see the bottom of the deep end for swimmer safety.
Which for you is anywhere between 2-12ppm fc
See—> FC/CYA Levels
* Please note that a one time addition of chlorine is not enough to rid yourself of an algae problem.
You need to do the
SLAM Process
With liquid chlorine.
