    Perilous CYA test question

    Am newbie...is "cya dilution test" different than the cya test in the tf-100 test kit? If so, what is it as I am just getting ready to SLAM after a pool refill and the CYA measurement is the key...thx!

    The CYA test in the TF-100 only goes up to 100. For readings of 90-100 it is recommended to run a CYA dilution test. You can try the CYA test using a 50/50 mix of pool and tap water (instead of all pool water) and then doubling the test result to get a little better idea of how much water needs to be replaced to lower the CYA.
