Chlorine levels

[Leinbach]

How high is to high for free chlorine to swim
in a Saltwater pool? I see suggested level up to 11 on the pool math app.

Depends on CYA --
You can safely swim in a pool as long as the FC is above the minimum and at or below SLAM level based on your CYA. You must also be able to see the bottom of the pool in the deep end of the pool.

My cya is 75. Believe the slam is 29. Current chlorine is at 12.

Then safe to swim in up to 31 ppm FC. CYA of 80 --
