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!
