Thread: 1st water test.

  1. Back To Top    #1

    1st water test.

    Water has been sitting for almost 2 weeks and is now cloudy and slimy. Here are the numbers. I have a aqua ps 15 SWG but it is not running right now as I am under the understanding I need to adjust my water 1st. I have read bbb but just want someone to put me on the right starting path. I would think bring up to shock level and when I pass the overnight test worry about the other stuff? 20k gallon inground

    Pool pool parameters are:

    pH: 6.8
    FC: 0
    Alkalinity: 130
    Calcium: 70
    Cyanuric Acid: 0
    Cc: 5

    Re: 1st water test.

    first things first how did you test the water...ie pool store strips? and IF those numbers are accurate the first thing i would do is get my ph up to around 7.2 assuming it is 20,000 gallons it would take 170 of team mule 20 borax to get the ph to 7.2. is this a new fill if not have you used any pucks or added any stabilizer? if not i would add 80 oz by weight of granular stabilizer in a sock in front of the return jet but dont let it touch the liner as it can discolor it which will get you to 30 ppm cya, and get , and go read pool school, shocking your pool and the abc's of water chemistry .......Mike

    Re: 1st water test.

    I think you just finished your pool and this is a new fill, right? Well, I am assuming that no chems have been added yet:

    As 1971 mentioned, first get the pH in the low 7's. A pH lower than 6.8 will also read 6.8, so make sure you retest after dosing and confirm the change.

    Second, add 30PPM CYA via sock method and start the shock process as described in Pool School.

    You will need more CYA later for the SWG, but all that should be done later. Use bleach/liquid chlorine to shock. Leave the SWG off for now.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Yes the pool should be done soon. The tests were done with the tft100 and you are correct nothing has been added.

    1st question. How long to wait after adjusting ph doni wait before testing and adding cya? I will get enough cya for 80 cya and put in enough for 30 for now. Just to confirm get any bleach the is at least 6%. Thanks.

    Adjust the pH, circulate for about 30 mins and retest to confirm that you have target.
    Once pH is confirmed, you can then hang the CYA sock in front of a return. Give it a squeeze every now and then to help disperse.


    I will get enough cya for 80 cya and put in enough for 30 for now.
    Yep.

    Just to confirm get any bleach the is at least 6%.
    Yes, but plain, unscented bleach. Clorox and Walmart brands are used lots around here. I suggest you stay away from dollar store bleach regardless of brand. You can also price liquid chlorine (pool store, walmart, big box stores) and see if you get a better deal. Thanks.

    Re: 1st water test.

    Thanks for your help butterfly. I have added everything this evening

    Fc: little above shock level at 15ppm
    Cc: .5 best I could tell might have messed up the test but will retest in the morning
    Cya: did not test.

    Thanks for your advice also Mike. I added 2 boxes of 20 team mule and my PH went up a good bit probably to much. I have also added more water since 2 days ago so may have had something to do with it.

    Re: 1st water test.

    The CYA can lower the pH ... so you are likely fine. Oh, and when the FC > 10ppm, the pH test is inaccurate and reads high.

    Re: 1st water test.

    Ph 7.8
    Fc 7.5
    Cc 0

    Do I need to add chlorine to shock now or at dawn?

    Re: 1st water test.

    You need to maintain shock FC level as often as you can ... possibly hourly at the start.
