    New pool test results

    Ok the T 100 test kit came in today.
    I shocked the pool (27' round AG) 2 days ago and was using test strips at the time.
    I added way too much chlorine -4lbs shock and 4 gallons of 12% liquid chlorine.
    The strips were not showing movement past 3% until I added the last 2 gallons of liquid chlorine.
    I ended up with a bright pretty purple color on the strip that wasnt even close to the chart on the bottle.
    These are the T 100 results:
    free chlorine 19
    combined chlorine 1
    total chlorine 20
    total Alk 200
    calcium hardness 100
    CYA 45
    PH NA - forgot to test - 7.8 on strip test
    So the chlorine is high and has stayed that way for 2 days.
    Is there anything I should be doing?
    I added 4 lbs of CYA.
    I did plug these in to the calculator BTW.

    If FC is that high, your pH reading will be questionable anyway. Deal with it later.

    Question: Is the 45 CYA reading before or after adding 4 lbs of CYA? Because 45 is already pretty high if you're shocking.

    Just follow the directions for shocking. Brush and filter until it turns clear. When the process is over and FC drops down below 10, run the full series of tests again and then deal with pH and the rest.

    The CYA was added 2 days ago.

    Re: New pool test results

    Was the CYA liquid or granular? If it was granular then your target FC will need to reflect a CYA reading of 45 plus the effect of 4lbs more. If you added liquid CYA, your FC target should use 45 for your CYA.

    I used granular CYA.
    I put it in a filter sock and hung it over the side.

    Re: New pool test results

    studboyz, could you add you pool details to your sig, it helps us out.

    Why did you add more cya? Do you have a swg?

    Please clear up my confusion on how much cya you have put into your pool, and when you put it in, and what the cya concentration was before you put it in.

    Re: New pool test results

    I first added 4 lbs of granular super shock then 4 gallons of 12% liquid chlorine.
    I used a test strip to check levels.
    CYA was showing 0 so I added the 1 lb of granular CYA that came in the start up kit.
    CYA still not registering and according to the package I needed about 3 more pounds.
    I bought another 3 lbs and added it.
    The test strip was showing CYA but it was not clear what amount.
    2 days later I recieved the T 100 test kit and got the results shown above.

    CYA can take a week to show up in tests. I would not add any more until you are done shocking.

    What was in the granular chlorine you added to your pool? If it contained cya (i.e. if it was dichlor or trichlor) with it you will need to know how much total you have added so you can find your shock FC level.

I would not add any more for now. Since is has been a couple of days since you have added it, for shocking purposes you can assume it is all in there and adjust your minimum shock level to 15 ppm (per pool calculator for 42 ppm). Test again for cya 1 week after you added the last amount to see where you are for sure.

    How is the shocking process going? I would use only liquid chlorine/beach for the shocking process.
