Before I fould TFP, I used the basic Poomaster test kit provided by my pool builder and double checked with a pool store periodically. I have a Taylor 2006C now, but my warranty requires a monthy pool store report, so I still go to my pool store at least once a month. They use Taylor Kits and fortunately they don't push bad advice and products on me. I notice That my 2006C pH readings are usually about .2 higher than their readings. I started double checking with my Poolmaster kit and it reads about .2 less than my 2006C kit as well. I think the 2006C colors are harder to differentiate than the Poolmaster colors. But, I don't think the color read is making the difference. I typically go with the 2006C reading because I expect it to be more accurate. Not sure if there is a real question here, but any advice? Maybe I should buy a new bottle of pH indicator for the 2006C and see if there is a difference.
