Just filled the pool yesterday and I am using my TFP testing kit.
I cant seem to get a CH reading. I have tested the pool water and tap water using my speed stir and I can't get the sample to turn blue. I have used over a hundred drops in each sample. At this rate I will run out of reagent in a couple more tests. Definitely feels as though I am missing something or doing it wrong.
Also, the pH is way high (>8). I have added the specified amount of MA several times. The pH hasn't budged after 3 doses. How often should I be adding MA and how soon should I expect it to have effect?
