    So, we did some make shift aeration this weekend. Seems as it had a small effect.
    Added 2 jugs of bleach after this test was taken.

    Posted new test results.
    Added 1/2 gallon muriatic acid to reduce pH levels. According to this post http://www.poolsolutions.com/gd/lowe...p-by-step.html
    I am going to lower to 6.8 as this is the lowest my tester will go, I will then begin the aeration to lower the TA.
    How long should I wait before the next dose of acid to lower pH?

    The aeration raises the pH, not lowers the TA. Don't drop the pH to 6.8 on your kit because by doing so, you don't know if 6.8 means 6.8 or any value lower. Lower it to 6.9 or 7.0 instead. You add the next dose of acid when your pH is raised back up to 7.6 or so.

    New results posted, seeing nice results in TA and CYA.
    Will continue aeration and add a small amount (1/4 gallon) of acid to lower pH.

    Looking good.

    I'd caution against testing CYA so often. There's a very limited number of CYA tests in the kits.

    It only changes when you add it (directly, or by using dichlor or trichlor), when you drain pool water, or when it's consumed by bacteria (usually over the winter).

    On the topic of disposing of toxic waste (as chlorine tablets would qualify)...You need to check with your town and possibly your county. I would presume that California, like New Jersey, has very strict laws on disposal of such substances (I have a can of gas that has been contaminated with water and I have to wait till October to dispose of it). We have only 2 collection days a year for it. You cannot just (legally) put it in the trash or wash it down the drain.
