    Safe chlorine level to swim

    Hi, I recently had to do a slam due to algee. The algee has been gone for 5 days now and the water looks crystal clear blue. I know my CYA is too high at 120. My TC is now 25.

    My question is, what is a safe level of TC before we can get back in the pool?

    Thank you.

    25 is safe to swim at.

    You should really consider replacing water to get your cya down.

    A pool with 60 cya and slamming at 24 could swim at 23.

    Yeah, my CYA was over 250 and now a lot lower but I have a ways to go. So, if I understand correctly, my 25 TC is safe for my kids, right?

    It is safe to swim when FC is above minimum and up to shock level for your cya, FC/CYA Chart.

    Just be aware at those high chlorine levels that the pH test is not accurate, FC needs to be below 10 ppm for the pH test to work right.
