When using the Taylor 2006 test kit for CH I get a wierd reading/response. When you add the drops that are suppose to turn it red I get a very light pink and then the pink starts to form into tiny droplets suspended in a clear solution.

I then start to add the the drops to turn it blue and I get to a point where it turns more of a light purple color. To the best of my ability I get a reading of about 250 ppm. I tried it on my softened house water and it worked just as the instructions described.

I have an IG vinyl/SWG pool, temp is ~85 F, FC=5.0, CC=0, pH= 7.5, and TA=140. My CYA should be about 50 ppm but I added it last Saturday so I've been waiting to measure it so it has a chance to completely dissolve.

Anybody know why my CH test acts so strange? Thanks!
