    Test result discrepancy

    So I still consider myself a "new" pool owner and need some help. I have a tft-100 test kit and tested the pool today. I got a FC of 2, CC of 0, pH of 8, Hardness of 275, alkalinity 30.

    I took a sample of pool water to the local store and got a huge discrepancy with FC 0.86, CC 0.15, pH 8, Hardness 148, alkalinity 35.

    I got both samples about elbow deep. Now the home test I got from a less deep part of the pool but don't think this could account for the big difference in chlorine and Hardness.

    Any help would be great

    For ref, I have a Jandy Aquapure with AquaLink salt water pool ~40,000 gallons I think.

    Re: Test result discrepancy

    Any comparison to a pool store test is invalid. Just throw them out, maybe a pH test exception. Trust your's, if you are concerned with your skill practice or watch youtube videos or videos @ TFTestkits.com

    In reality, the results are fairly similar. Neither result has a CYA reading tho??

    Why bother comparing your results with those guys? Us guys give better advice! Trust your test.

    Re: Test result discrepancy

    Could j be doing the tests incorrectly? I follow the instructions in the TFT-100 kit. And it is pretty dang simple so don't know how I could be messing it up.

    Unless they are using the exact same test method you are using I would trust your test results. If the pool store was using a computerized tester I would not trust it at all.

    It was a computerized tester at the pool store. She said trust her readings of course.

    This is why we insist on people getting their own test kit. It isn't to sell kits or because we laugh at making people spend $70, it is because we just cannot trust pool store testing. As you can see, some were close, some a little off, and CH not even close.

    You followed the directions in your kit, trust those numbers. No need to ever 'verify' your numbers at a pool store, you got this!

    There must be a part of you that still thinks the pool store is where the experts are. Wrong! We are HERE!

    Realize that the nineteen year old who works there from may til august knows nothing about water...just owning a tf 100 makes you the smartest pool guy in the store each time you walk in!
