    we have a situation....TC..0, FC..0,CYA..0, PH..<6.8, TA..0

    what in the heck do I have in my pool? Can you still call this H2O?
    Now, I must confess, that I haven't checked my water since we had our SWG installed in May this year. The water looked sparkly an clear and I thought we are good to go....obviously looks are deceiving!I bought some AquaChem test strips and

    TC..0
    FC..0
    CYA..0
    PH..<6.8
    TA..0
    Hard 250
    Salt 2.4

    I do have a TF-100 kit, but I ran out of a lot of the reagents and it is 3 or 4 years old. Yeah I know, I am a slacker...sorry , so off to WallyWorld I went and bought 4lbs12oz borax, 12lbs baking soda and 3lbs stabilizer and dumped that in the pool, stabilizer in a sock in skimmer. I did order a new test kit, but it takes a bit to get here. What else can I do to get my pool back in check? My plan is to let the pump run over night and re-check my numbers tomorrow...and pray!!!

    I don't see you added any chlorine. You should add some bleach to help the SWG get going or you'll have some green water.

    I think you know how we feel about those strips.

    Don't believe test strips. They are les accurate than pool store testing. Until you get your test kit back online, take a sample to a pool store and have it tested. Don't buy anything whle you are here, just get he test results. You want:
    FC
    CC
    TC
    pH
    TA
    CH
    CYA
    salt ppm

    BTW: I don't know how you can have a salt level of 2.4. I don't believe any of your numbers can be accurate (well maybe the CH 250). Post some real test results and we will help you get started on putting things right.

    Re: we have a situation....TC..0, FC..0,CYA..0, PH..<6.8, TA

    Had the water tested, of course they tried to sell me all kind of stuff, when I told them, that I use bleach to shock, they almost had a nervous break down and told me how bad it is for my pool, since I didn't wanted to buy from them, they charged me $25.00 for the test....anyhow her are the numbers:

    FC...0
    TC..0.4
    pH..<6.2
    TA..38
    Adj. Total alk..26
    Total Hardness..28
    CYA..40
    Salt..2700

    I started to add baking soda, hope that's the right approach, in what order should I adjust the rest ?

    You need to get your self one of our recommended test kits. Pool store testing doesn't cut it here.

    First adjust pH with borax to the low 7's. Then, test/adjust TA up to 60ish.

    Next, follow the SLAM process in Pool School.

    After the SLAM process is completed (see red lines in my sig) you should increase CYA up to the recommended SWG levels.

    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.

    How in the world did your pH and TA drop while using a SWG? That does not make sense. Have you been adding any chlorine powder or pucks?

    A SWG did not make the pool maintenance free. All that slacking has caught up to you. Order a refill kit and take back control.

    ...no powder or pucks....! But the pool dude who installed the SWG just dumped 4bags of salt in the existing, chlorinated water. Does that have some to do with it? He didn't checked my chemicals before nor after installation.

    Salt should not affect the pH.

    Your FC is too low, it should never be below 4ppm: pool-school/chlorine_cya_chart_shock
    And your salt seems too low for the SWG to even be functioning.

    I would recommend raising the FC up to at least 10ppm with bleach, turn off the SWG and Perform the Overnight Chlorine Loss Test. If you fail, you will need to follow the SLAM Process.

    Thanks for your answer, but I can't turn my SWG off unless I turn the filter off. The pool dude connected the SWG to the timer of my filter, the SWG automatically runs when the filter runs. Is that a problem?

    Re: we have a situation....TC..0, FC..0,CYA..0, PH..<6.8, TA

    Then set the output of the SWG to 0.
