    Still no hardness?

    I just refilled my tub. Soft water.
    My Taylor kit test says the sample should turn red if calcium is present. It didn't so I added 10 oz. calcium chloride and ran jets.
    Tested again and still no red. Added 10 oz. more and ran jets. Still no red. Tried my HTH test kit thinking maybe Taylor test was off. Still no red.
    What gives? Could my (old) calcium chloride (Balance Pak 300) have "gone bad"?
    Now I'm nervous that I've over-hardened my water and will need to start all over.

    I doubt your calcium went bad. Your test *maybe* ? How old are your reagents?

    It's not the reagent getting bad. Double check the dose and your test procedure.

    Taylor kit and HTH kit both @ 2 yrs. old.
    Pool Calc said I needed @ 11 oz. of calcium chloride or 20 oz. of of calcium chloride dihydrate.
    Not sure which I have so I started with 10 oz. and got no red. Added 10 oz. more and still no red.

    Well, your dosage is good so I think your reagents are faulty. 2 years old is probably too long to be reliable.

    Take a Giant step into pool management and get the TF-100 of Taylor K-2006C

    I'm using the TF-100 kit. Twice.
    Then I tried my HTH kit.
    Neither indicate any hardness.

    You might need to reorder the reagents. Do your other tests seem to be accurate?
