    Default HTH Test Kits

    Does the chemicals in the HTH test kits expire??
    I've had mine since last year, but have quite a bit left in the bottles.
    Thanks

    Have you kept them in a cool, dry, non-freezing place? If yes, probably OK.

    These kits are relatively inexpensive - buy another one and comparison test if they read the same, you can trust the old kit enough to use it Monday, Wednesday, Friday using the new kit Sunday, Tuesday, Thursday, Saturday.
