    Test numbers - how do they look?

    Been trying to get the water balanced. Here are my current results:

    FC 7
    CC 0
    pH 7.4
    TA 50
    CH 130
    CYA 50

    I was thinking of using Cal-Hypo until CH comes up to the 220 range, but that might take a long time. Looks like I need to add about 5 lbs of baking soda to raise TA to 70. Any suggestions?

    How do you chlorinate? SWG or manual? How does your water look?

    I manually chlorinate. I've been using bleach to SLAM for a few days and the water is gorgeous.

    I'd say you have things figured out.

    Yes to raising TA with baking soda.
    I don't know that I'd worry about CH in a fiberglass pool. But some simple number crunching says that if you lose 2 FC each day and use Cal-hypo to chlorinate, you'll add 10 CH every week. A 25 lb bucket will add 87 CH. Your call.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    If CH is not critical with fiberglass, I'll just raise TA and enjoy the pool. Bleach will be much cheaper than a big bucket of 73% cal hypo from the pool store.
