    swimming/shocking

    Hi...I'm SURE this question has been answered, but I'm inept at 'searching'!!

    My pool is almost back to sparkling blue again!! YAY!! Still slight CL drop this morning. HERE's the question:
    It's a beautiful, HOT day here in SW Florida. The pool is beautiful.................can we swim????

    I tested the CL this morning...it was about 13. I added more to boost to 19 about 3 hours ago. (there are some sad and pleading faces looking at me.......)
    Sunny SW Florida! Uncaged Free-form IG pool, Pebble-tec finish, 20,000 gallons?? (Beach entry/tanning ledge is 9' x 9'; it's free form 37' x 19'. Depth 3 feet to max 5.5 feet. There's also an attached spa with spillover: 6 foot radius. Anything else?)
    Prologic computerized thingie with SWG; 1.5 hp Hayward II Super pump, cartridge (i think) filter. (Hubby contracted the whole thing...so I don't have a detailed list on what we've got!)

    What are the rest of your test numbers? Basically, if your FC is below shock level for your particular CYA level, it's fine.

    Re: swimming/shocking

    haven't done a full battery of tests since I started 'shocking' on Tuesday. Here's what I had then:

    pH was 7.8 (I have added acid since)
    tA 70
    CH 115
    CYA 30
    Salt 2800

    Been trying to keep Cl at 19, but it does drop.

    Based on the Chlorine CYA Chart, you are below shock level once your FC is less than 12 ppm (since your CYA is 30).

    BTW, are you keeping a CYA of 30 only because you have been shocking? Typically, you would want a CYA between 60 and 80 when running a SWCG.

    Yes, I'm keeping it lower while I shock. I think I'm *almost* done, though...so I'll be adding stabilizer soon!!
