    Testing Old Bleach

    Is there a trick to testing a few old jugs of bleach that were sitting on the shelf for a few years? I have a few jugs with low odor and I think they have significantly degraded. Not really concerned but just curious.....

    If not I'll dump 'em in and deal with it.

    Not easily. Dump them in and measure in 30-60 minutes.

    I assumed that was the case.

    Wait wait, there is a way, let me look in my Pool Book (notebook of things from the forum)

    Testing Bleach:
    Use 2 syringes or pipettes, Clean bucket, distilled water. (requires 2 syringes or pipettes to not contaminate the testing)
    10 ml bleach in 1 liter water, take 10 ml of that mix (into second clean pipette or syringe) and add to another liter of water.
    Mix and test. Each drop (of testing reagent) = 0.2% bleach (strength)

    My pool book has all sorts of handy hints like that, along with instructions that I copied from the forum about things that were new to me (everything!) and details of pool equipment, local stores for chems phone numbers and recent pricing.
    23,000 gallon in ground pool with rock waterfall and spillover spa, Aqualink control system, Polaris 380 cleaner, Purex Triton Clean&Clear Plus cartridge filter. Located in The Woodlands, Texas.

    Sounds like a lot of work for little gain.would that change your decision to use it?
