Well I searched several threads but I just want to make sure I got this correct:
In order to save a little R-0871 reagent, I can use 5 ml of pool water and 5 ml of distilled water (to total 10 ml). If I do this, then however many drops I add is my actual PPM chlorine, is that correct?
For example, I added 14 drops before it went clear so my FC is 14? (as opposed to 7 if I had used 10 ml of pool water)
(I know it's not quite as accurate, just trying to save a little until my order of more comes in)
