    Pool Store Readings - Help!

    I'm out of town and my wife had to get the pool water tested at the pool store nearby. They do it for free and never try to sell us anything, so when I'm not around, we use them and when I am, we test ourselves.

    They seem to have changed their system and gave her results below (they used to just write down the results on a note paper).

    How do I interpret the CYA reading? Should I be using 100 or 50?

    I always use these as my guidelines from TFP:

    Vinyl with SWG
    FC 3-5ppm
    pH 7.5-7.8
    TA 60-80
    CH 50-300*
    CYA 70-80

    Would your wife be interested in learning how to test the pool herself so you could eliminate the pool store altogether? Just a thought.

    Unless you exchanged a lot of water I would just assume CYA was whatever you last tested it at. There is no reason to trust that number.

    Also, FC 1-4. LOL

    Not sure I understand the question. Your CYA according to the pool store test is 100. They measured your TA at 50.

    IMO, pay no regards to any of the pool store test. If you are using one of the recommended test kits always trust your testing

    Don't trust the numbers of the pool store. I literally posted minutes ago my experience yesterday with a pool store telling me I had a 100 CYA reading 6/17 and a 10 CYA yesterday. That 100 CYA number was a screw up and the owner admitted and apologized for the store's screwup.

    I'd hate to drain 45% of my pool water because of a pool store screw up.
