    How many drops of orthotolodine?

    I replaced my Taylor test kit drops with some other brand when I ran out. I can't remember how many drops to use of this particular kind. I think last summer the directions said 3 drops, but my ph color was so light I could barely see it, so I just started using 5 drops. Will this make a difference in ph and Cl results? Attached is a photo of the stuff I'm using.

    You really can not mix and match brands of regents and color comparison vials. They may have different ingredients and concentrations and water sample sizes.

    For the Taylor test block and the Taylor regents, it is 5 drops. Who know what is in those bottles and what comparison block you are trying to use.
