    FAS-DPD test

    Forgive me if this info is in Pool School, but I haven't been able to find it.

    When I'm testing the chlorine levels, do I use a level tiny spponful, a heaping one, or something in between. I've been using a level spoonful.

    All of the above. You want enough to cause a definite pink color. The exact amount is not really THAT critical. I start with a slightly rounded spoon and if i don't get a pink color i add another. If I KNOW my chlorine is very high because i am shocking the pool then I start with a heaping spoon.

    A heaping one. Just make sure you don't use the paddle side. Use the bowl side or you will be wasting it.

    If I put a level scoop in, I get a bright pink color.

    The little curved end, it's a tiny scoop. The flat paddle side is the handle.

    Re: FAS-DPD test

    OMG I just went and looked at my scooper. No wonder I ran out of the DPD. I was scooping with the other end
    Just another rookie mistake. And the bad thing is, I ordered 2 of the DPD

    Re: FAS-DPD test

    I did that too at first. I don't think it's uncommon to make that mistake....

    Waterbear posted something about vacume sealing the DPD powder to save it for later. Any chance you can do something like that?

    The FoodSaver is one of the BEST appliances I have ever bought! I keep finding new uses for it.

    As waterbear points out, the amount is not critical as long as you use enough. It is an odd property of that powder that you can't use too much of it. Too little, however, will cause inconsistent results.
