    Measuring all this stuff

    You guys have awesome ideas for everything so I'll see what you suggest for the following:

    What's the best way to measure 4 lbs of DE from a 25 lb bag?

    What do you like to measure 69 oz liquid chlorine in? Same thing for muriatic acid?

    Just curious. I'm using a 4 cup Pyrex measure for the liquids and a bucket eyeball method for the DE. Just looking for an easier way.

    Re: Measuring all this stuff

    I use the pool math
    "by volume" amounts, and measure using a plastic one quart measuring cup.

    DE is about 48 fluid ounces per pound. Don’t use any type of glass around a pool.

    Yes I use pool math. I meant what type of measure. So plastic measuring cup will be on the list to buy.

    So you mean using a liquid measure of 48 oz will roughly be a pound? Assuming it isn't packed tight (thinking of flour while baking). With that I could do 8 scoops of 24 oz and be done! Is that right?

    Re: Measuring all this stuff

    I use a kitchen scale and do my powdered chemical measurements by weight. The volume estimates for solid materials is probably good but I know the weight is right on. For muriatic acid and bleach, I just do eyeball on 1/4, 1/2 or 3/4 of a gallon. I do have a gallon plastic Pyrex pitcher I've used for MA and bleach a couple times but I don't like pouring MA any more than I have to so usually straight from the jug.

    (8) 24 oz (Volume) scoops would be about 4 pounds of DE. (Loose, not packed).

    Re: Measuring all this stuff

    I have a cheapo plastic scale that I relegated to the pool house for powders, and a large quart sized hospital patient mug that measures liquids in ounces and mL.

    I noticed yesterday at Lowes some cheap measuring containers in the paint department. No handle like my mug has, but clear easy to read measuring marks and dirt cheap. Might be useful!

    Re: Measuring all this stuff

    I have two plastic measuring cups that are different colors. I got them at the dollar store. One lives with the MA and is used ONLY for it and is kept with the MA away from everything else. The other is for everything else. I just use the oz on the side of the cup for liquid and dry. It works for me.
