    Welcome to TFP!!!

    As we tell just about every new member:
    1. Read Pool School to learn about the chemistry and methods we teach
    2. Order yourself one of the recommended test kits. Pool store testing is worth as much as you pay for it.

    We never even test or worry about TDS, Nitrate or P (phosphates?)

    If those results are to be believed, the only suggestion I would make for a SWG pool would be to increase the CYA (although that is the test that pool stores are notoriously the worst at).

    Welcome!

    Yeah, what he said. ^

    Pool store results are sketchy at best. Recent horror stories include the guy who was advised to drain half his pool to lower CYA and when he brought back a sample after the refill, was told the CYA had gone up 25%!

    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!

    I have the same advise, but wanted to add most people get a LOT more out of pool school the second time around, see the link in the upper right of this page.

    p.s. the best common test for CYA is a turbidity test which really needs correct lighting conditions to get a good reading, the correct lighting for the test is bright sunlight to your back while viewing downward at arms length. Trying to do this indoors under artificial light in a pool store while in a rush is a recipe for crazy readings. There are other types of test for CYA, but they all fail miserably in accuracy.

    That's GREAT advice. I hadn't heard about the lighting being so much of a factor. I had read about your back to sunlight, but I had been doing that test indoors. THANKS!!!!!!!
