I ran out of my Taylor R-0014 ph phenol red indicator reagent, went to pool store and they only had R-004. I've been using R-0014 for years with my original Pool Solutions test kit and refilling as needed when running out. When I used the R-004 reagent, the resulting color was WAY more red/purple that I've ever seen and my pH was off the charts and dark purple. I've never seen that color.
Quite confused right now. Not sure if my pH is really that high or I'm using the wrong reagent.
