    Default How often to do each test?

    I just got Ben's kit. This is our first year using chlorine. Could someone please tell me how often to do each test. Also, what numbers am I shooting for on each test? I already tested the CYA and it was 30. Is this appropriate?

    Default Re: How often to do each test?

    Test chlorine and ph every day or at least every other day. Every couple of weeks is probably ok for alk and cal. CYA a couple of times a season is plenty. CYA of 30 is fine.

    Good readings:
    PH 7.4-7.6 (but anywhere 7.2-7.8 is acceptable)
    Alk 80-125 (although if it is a little higher, no problem)
    FC 3-6 (for a cya reading of 30)
    CC zero (FC + CC = TC)
    Calcium hardness 200-400 (but not needed in vinyl pools)
    CYA 30-50
