    Oh, yes. Those projects you're gonna get done when you get around to it. I've got some of those. But I still haven't gotten the projects done.

    However, I do have a nice round tuit:

    PoolDoc, thanks for the tip -- after three days the Cl snapped back and the water's crystal clear again.

    New numbers:

    Free Cl = 5.8
    Combined Cl = 0.2
    Total Cl (OTO) = 3.0
    pH = 7.4
    Alkalinity = 120
    Cya = 70 +
    NaCl = 3000

    (The pH dropped to 7.0 when I added cyanuric acid and I bumped it back up with borax)

    I'll keep adding bleach for a week like you suggested so I don't have a recurrence (just added an extra pint this morning because I expect a heavy swimmer load for the 4th).
    Intex 18' Round 53" Deep AGP, approx 8000 gallons, full sun all day.
    Intex 14" Sand Filter Pump, 1600 gal/hour, Intex SWCG Model CS7110.
