    Going to close tomorrow - numbers ok?

    I'm planning to close the pool tomorrow. Here are my numbers. Are we good to go?

    FC 13
    CC .5
    TC 13.5
    PH 7.8 - 8.2
    TA 120
    CH 220
    CYA 90

    Due to leaves getting into the pool, I've been keeping my FC high. I stopped adding bleach 2 days ago to let it get back down to a normal level.

    I think that PH is high because of the high FC. Normally, it has been 7.8.

    Should I try to bring the CH up a bit?

    I'm going to the pool store and all that I plan to get is a gallon of anti-freeze and some stain preventer. I have a half a bottle of poly60 which I'll put it.

    Don't buy your antifreeze at a pool store. They will rob you blind. You can find it at Walmart for ~$5 a gallon, or farm stores around here have it for $2.69 a gallon right now.

    With your CYA at 90ppm, 13ppm isn't really a very high chlorine level since 10ppm is the recommended level for a non-SWG pool.
