    First Test Results VS Pool Store

    Just getting started----pool looks great but.....

    Been at working until 8-9pm last few days.
    Wife was mistakenly adding Muriatic acid instead of chlorine liq.

    Robertson's Pools--Frisco--Automated Testing

    Sat Index 1.1.
    TDS 1400
    CYA 75
    Total Cl- 0.1
    Free Cl- 0.1
    Ph 8.1
    Total Alk- 148
    adj TA 128
    Total Hardness 529



    TFT 100 Kit


    Cl- Questionable pink? very slight if at all. I'm calling zero.

    Total Alk 180

    CYA 50-70 wife vs my vision

    Ph 7.8 (K 1000)

    TC by (K1000)===None

    ETA: Used pool math and will test later!!!!!!

    It's fun playing chem lab again.

    Re: First Test Results VS Pool Store

    Are you positive, your wife was adding MA and not chlorine? Your PH should be very low. With 15,000 gallons, every 10 oz. of MA will lower PH by about .2. A gallon would of sent the PH way below what you are testing. Forget the pool store testing and stick with yours as it will just complicate things.

    Please post a full set of results and please follow the instructions on the yellow card. If you have the speed stir, it should only take a few minutes:

    FC
    CC
    TC = FC + CC
    CH
    TA
    PH
    CYA


    Please check TC and CC with the drop based kit to start. This will tell if you will need to SLAM.

    Plug in your figures into pool match and check out your CSI. (Calcite Saturation Index)

    http://www.troublefreepool.com/calc.html

    I am not 100% on the CH as I believe Texas water is high in this area. TA seems a little high. Recommended levels are as follows:

    Pool School - Recommended Levels

    Do you keep a timeline of your levels? Are you having issue with PH rising and that is why Muriatic Acid has been added? Definitely recommend you perform an overnight test.

    Pool School - Perform the Overnight FC Loss Test (OCLT)

    CSI 0.6

    I''ll monitor Ph daily for awhile and see how it goes.
    I'll study up on overnight test.

    Texas is a big place and has a LOT of variation on fill water, particularly on the topic of CH. While I am not in Texas, I am only about 20 miles away from Texas as the crow flies and my fill water CH is usually around 50 ppm depending on time of year, the lowest I have ever tested came out at 30 ppm.

    Our water in Dallas is fairly hard and fairly high TA. My pool has been filled for a little over 3 years and the hardness started at 160 and is now 410. I have to actively lower TA following this process, Pool School - Lower Total Alkalinity

    Here is what Pool Math has, and I believe you are right there on the levels (borderline). Please play around with the figures and lower PH to determine if your CSI is lowered. There may be other ways to lower the CSI, but maybe someone who is out in that area can help you out. Luckily, in our area, our fill water has near perfect levels on PH, CH, TA. I made a mistake of adding well water in the beginning, but it was in such small amounts that there was no effect to the total picture.

    Calcite Saturation Index - requires pH, TA, CH, CYA, Temp, uses Borate, Salt Less than -0.6 is suggestive of problems for plaster, tile, stone, and pebble pools. Greater than 0.6 is suggestive of problems for all pools.

    Re: First Test Results VS Pool Store

    PoolScreenshot.jpgGood morning.
    Thanks for info.
    Will be working on stuff slowly
    I intentionally waited for cool weather to be close so that any mistakes I make will be in a more forgiving climate.

    Re: First Test Results VS Pool Store

    After a year of liquid chlorine, I have enough salt in the pool (3500) that it mitigates the higher CH of my water, so I don't have to keep my pH in the low 7s to avoid scaling.
