seabright_sc Posted December 17, 2010 Report Share Posted December 17, 2010 I've used the search but still can't find the enough info. I'm using Taylor test kit for hot tubs and I have a hard time with the PH test. On the test block the colors go from a yellowish orange to grades of pink/purple. But all of my samples are shades of orange. At first I thought that the PH was just a bit low so I added PH increase. It just seems to change the shade of orange in my test sample. Yes the regents are less than a year old and stored properly. What gives. The only thing I have been trying to do is to match the shade of the water sample as opposed to the color itself. I've held it up to a light colored background in natural sunlight etc. Doesn't help. Any advice? Quote Link to comment Share on other sites More sharing options...
