    Recommended Levels

    I found this statement in the Recommended Levels FAQ: If you are using trichlor tablets for chlorine, follow the bleach recommendations but have TA around 100-120 and be sure it doesn't fall below 100.

    Question is, what happens if the TA is below 100?

    Re: Recommended Levels

    Trichlor is acidic, so it is constantly lowering both the PH and TA levels. If your TA level gets low for just a moment, that is no big deal. But what usually happens when TA goes below 100 is that PH and TA both fall fairly rapidly to much lower levels, and that can be a serious problem.
