    My first water results

    Hi All,

    I made my first water test this week. The water was at 60 degrees. I have a saltwater pool.

    Salt 1350 ppm - I triple checked this test with the Aqua Test strips and the Taylor drop. Rechecked at room temp too.
    Total Chlorine 0
    pH 6.6
    TA 10 ppm
    CH 20 ppm
    CYA 0
    Borate 0
    My tap water has 90 ppm for CH

    My cover is still on and I have not turned on the pump yet.

    The pool calculator says I need 350 pounds of salt and 12 pounds of CYA. I just purchased these. I'm thinking I will start the pump this weekend and get the salt level up to target add the CYA and fire up the SWCG. When the chlorine gets to target, I will start adding the other chemicals. Currently, the water is cloudy but not green.

    Any advice or tips? This is a 2 year old pool but is my first season with it.

    Re: My first water results

    With water @ 60 degrees, I would start the pump and get chlorine in the pool very, very soon. (algae is not far away) So, to do that, I would...

    A. Run pump for an hour or so and retest. Assuming the results were the same I would

    1. bring pH up to 7.2 with 20 mule team Borax

    2. Put in enough Clorox to get to at least 3-4ppm and plan on adding enough to keep it there constantly.

    3. If TA is still below 70-80, add enough baking soda to get it there.

    4. Add enough CYA to get to 60-70ppm

    5. Add salt

    6. Start the SWG and adjust it to keep FC around 2-4ppm

    7. Adjust CH to about 250ppm if it's a plaster pool.

    You may need to shock if your pool doesn't turn clear. If so, do it with Clorox, not the SWG.
