some time ago i ran out of R-0871 reagent. i bought a 2oz bottle of R-0871, opened the dropper on my original 0.75oz bottle and poured some of the fresh reagent in.
now it appears to me that the drop size is smaller coming from R-0871 that R-0003. i don't know if it was like that before of if removal of the dropper and re-installation messed it.
can someone take a look next time you do the fas-dpd test? smaller size of the drops would result in artificially higher readings and i don't want to run on lower chlorine levels.
