    New pool, figuring out testing. PH/TA questions

    Hi all,

    I've got a new IG gunite pool that's been operational for about 4 weeks. It's about 25,000 gal.

    My plan all along has been to maintain my own pool since I'm able to deal with it daily instead of waiting for a visit from the pool guy. We've got a pool guy coming once a week as part of the build, so I've been trying to match up my chem readings with his.

    I'm using the TF-100 test kit, and I can't seem to match up my PH and TA readings with the pool guy. Last monday, he said I had 90 TA, but when I did the test (multiple times, different parts of the pool), I keep getting 20-30. Also, my PH seems lower than his, but I'm just using the blue test kit, which I don't think is exact.

    I'm *guessing* that he's right, and I'm wrong, but I want more proof. Is there another test I can use to verify? Is it possible I'm doing something wrong in my testing?

    Thanks for any advice I can get!

    I am guessing YOU are right. If you followed the instructions multiple times for TA for example, and got the same reading, trust YOUR tests.

    I wouldn't assume he is right. Do you know what he is using to test?

    Post your full test results.

    Yes I do. He said TF-100.

    Test results as of about an hour:

    FC: 3.5, CC: 0
    TA: 30
    CYA: Hard to say. I thought I could see that black dot the whole time, but at 20, it was hard to see.

    Also, by the time Monday rolls around, Chlorine levels are < 1, and the pool guy dumps a bunch of chlorine, and I'm out of the pool for 8 hours every monday. That seems wrong to me.

    PH (from the blue kit): Looks b/w 6.8 and 7.2, so I'm calling it 7.

    I think you're both agreeing. I think Linen was meaning that we shouldn't assume that the pool guy was right.

    I agree with both of you. I think Bobby's test is right, and I don't think the pool guys were. How's that for walking the fence?

    Bobby -- You'll do yourself a huge favor by taking over the maintenance of your pool yourself.
