I couldn't find anything by searching. Having an odd thing with my test, TF100 alkalinity. I've done it several times before with no problems, however today, as soon as I put a few drops of the green reagent in, the test turns red. Never turns green at all. Does this mean 0 alkalinity? Also of note is that my PH is very low, below 6.8 by a good amount I imagine. I am finishing up the last few days of a new plaster startup and the service company doing the startup was here today to balance the water. No clue what they did other than obviously a ton of acid. Thoughts on the goofy test results? Thanks
