    algea and balancing my pool.

    Ok. SO I have a 24' round AGP.

    Here are my numbers:

    82 degrees water temp.
    13.5 FC
    0 CC
    40 CYA
    7.5 PH

    My wife wants to know if it is safe to swim in with the chlorine level being 13.5. Local pool store said no the level is too high?

    Thanks. I have been trying to figure this site out for the last year and I feel very challenged at times doing so...

    The shock value for your cya level is 16. It is SAFE to swim up to your shock level and you're below that. JUMP IN!

    Per the CYA-Chlorine chart http://www.troublefreepool.com/pool-...ya_chart_shock your shock value for a CYA of 40 is 16. You're below that, so as they say here : " less than shock value is safe to swim in"

    Is the pool green and/or cloudy? I would be wary of swimming in that... probably not a huge health hazard, we've all swum in lakes, but who wants a bunch of algae on them?

    No, the pool actually looks pretty clear now.

    My wife was just concerned with the level of chlorine and she called the local pool store and they told her that 13.5 was too high to swim in.

    Re: algea and balancing my pool.

    Pool store advice and our suggestions will not mix well. The pool store probably knows little or nothing about the FC/CYA relationship so they don't understand why you can swim in higher FC levels if your CYA is appropriate.

    Not saying you (her) should not get another opinion, but saying the info WILL be different....often drastically

    That's a big reason TFP is the most followed forum on the net. Everything we suggest here is rock solid science.

    Swim or no swim is always your choice.
