Noticed my 6pm test failed. It's been really consistent. Currently at barber shop and log in to see it and noticed the error. Manually started another test. Noticed pH is at 8.17 and staying there. Not dropping anymore

I forgot to respond. I went home noticed no reagent in the line at all. I moved the bottle over and I guess didn't realize it was halfway down the bottle not touching bottom. Pushed line down. Bled the reagent line. And ran it. 3 times. Back to reading 7.6Check for bubbles in the line.
