    Safe to get in Hot Tub (FC 14)

    Hello, I have an in ground pool with a SWG.

    We haven't used our spa or pool all winter. We were wanting to use the spa so I decided to test the water.

    The FC came back at 14 which shocked me, I'm assuming I'm running my SWG at too high of a %.

    Also tested my CYA at 20.

    My question is, is it safe to get in the hot tub with that FC level?

    Thanks,
    Steve

    Probably, but I don't recommend it. As a general rule, swimming/soaking is fine up to shock level for your CYA level. Shock level for CYA at 20 is 10, so you are a little too high.

    Thank you Jason. That's the conclusion I came too after seeing the CYA chart, just wanted to double check. The skin on my hands is stinging a bit just from working in the water a bit earlier.
