Not sure what happened to it as I seem to have everything else, but somehow I have lost the plastic mixing bottle used to combine pool water and the CYA reagent. The directions say to add water to such and such a line and the reagent to another, etc. Then from there, I add it by drops into the vial until the black dot disappears.. I'm sure I can order a replacement, but until I do, does anyone know the actual amts of water and reagent I need to add (in ml) so I can test it quickly? Thanks.
