    Chemical Order

    This year, I started with pool store instructions and, after a frusterating week, found this place. I'm just wondering, for future refrence, what order should different chemicals be added in? Also, what chemicals have to be added alone? I know this is prettyr vague, but just wondering....

    I usually have to add ph plus, cya, calcium, alkalinity plus, and, of course, shock.

    Re: Chemical Order

    There are a lot of special cases. A simplified list is something like:
    ---
    If TA is below 50, raise TA to 50
    If PH is way out of range, adjust PH
    If CYA is way too high, lower CYA
    ---
    Chlorine
    PH
    CYA
    Raise TA if needed
    CH, adjust CH on it's own day
    Lower TA if needed

    Thanks! I've always just did what the pool store said - and bought their stuff.... But their solution to anything is to buy more stuff!! I'm going to buy a good test kit and follow advice from here!!

    You will be surprised at just how fast it all begins to make sense. Then you will be amazed at how easy it all becomes. Then you will wonder how other people can stand to keep their pools the way the do when it is really not that hard to have a totally clean sparkling gem of a pool. And, weirdly, it is cheaper.

    I always start with CYA as so many people are over stabilised if water needs replacing why waste good chemicals.
