    Just received my water testing kit, results within

    I received my TF100 XL kit w/ Speedstir Magnetic Stirrer yesterday. I brought in a pool guy to ONLY vacuum the bottom of the pool as it had a lot of debris due to the previous owner of the house neglected it. You guys convinced me to get a Doheny's Discovery that should arrive in 2 or 3 days . I asked the pool cleaner guy to give me an estimate on the size of the pool in gallons and he said he estimates 15,000 gallons.

    Here's the results below:
    CL 1-2
    pH 7.8
    FC 1.5
    CC .5
    CH 550
    TA 260
    CYA 110 or 120


    Should I do a slam or how should I proceed first?

    Thank you!

    You ain't gonna like this, but I suggest you drain half way and replace water to cut that CYA in half or so, then retest it. Or two 1/3 partial drains and refills.

    Re: Just received my water testing kit, results within

    I'm trying to figure out how to drain it. Here's some pictures, please help me identify what's what:
    http://screencapture.it/2017-05-07_1434fghfgh4.png --- This picture is in the rear of the house by the pool so it seems to me that's where the water should come out if I drain it correct?
    http://screencapture.it/2017-05-07_1436dfdfdf.png -- Main pool underwater skimmers correct?
    http://screencapture.it/2017-05-07_1436tgfgh43.png -- Skimmer in and output

    Let me know if you need more pictures.

    Thanks again!

    Re: Just received my water testing kit, results within

    Did further research, seems I need a hose as there's indeed a pipe that's open and doesn't connect to anything. I need to setup something like this video: http://screencapture.it/2017-05-07_1547rfhgfh4544.png . Whenever I moved the valve water started coming out from it. My only question I now have is why is there what appears to be an outlet at the back of the house?

    I've drained about half the pool or so and the CYA results are now showing around 80-85. Seems I need to drain 1/3 of the pool to achieve between 30-50. Correct?

    Great news everyone, after the second 60% water drain my CYA is now between 35-40, I checked it 3 or 4 times. I then checked the 2 most important things Cl and pH

    Cl = 0.5
    pH = 8.2

    I guess I need to purchase some liquid bleach at Walmart.

    Re: Just received my water testing kit, results within

    So here's my new measurements
    pH 7.0
    FC 3.5
    CC .5
    TA 110
    CH 175
    CYA 35-40


    I guess I went a little bit too much on the pH reducer. Only thing that remains appears to need to be stabilized is CH. I still need to have an accurate measurement of the pool, it's between 10,000 gallons and 15,000. But with it not being in a perfect rectangle it's hard to measure. Are you guys/gals able to estimate with the below pics?

    The pool is looking GREAT. This is the best I've seen it since I moved into the house early May

    Re: Just received my water testing kit, results within

    My new numbers:

    pH 7.5
    FC 4(need to increase it to 6 or 7)
    CC .5
    CH 225(should I increase it to 250?)
    TA 80 (I need to increase it to 110)
    CYA is now 30-35

    I have a spa attached to the pool, does that change anything?

    Thank you,

    All of those levels appear as expected aside from maybe the CC. No need to raise the CH or TA, those are within target range. Your need to increase FC is correct, go for 7.

    CC is .5. When you added the R-0871 the sample went completely clear correct?

    Correct, after adding one drop of 0871 it went completely clear so I multiplied that 1 drop by .5 to get the CC.

    Your numbers look good to me. Just add cl till you get to slam level for the cya and keep going. My outdoor has a ta of 70 and likes it so you might even be spot on for your pool for the measuring of your pool and spa, I'm not even going to try!
