FC is Zero.Elevated.
What is the FC?
More so in person than it appears in photo.Using 4 drops it’s pretty much a dead ringer for 8.0
Notice the white vinyl fence in the background.Use a white background. Sheet of paper, etc.
I'm seeing about 7.6. I think that most people read pH higher than it actually is.
You have to go by the hue more than anything else.
I too have had some difficulties discerning the color match. Is the pH meter considered by TFP to be a more accurate means of measuring pH?
I too have trouble distinguishing the PH in the kit and use the PH Meter to verify what I'm seeing. In my 1 week of use, I have not had to calibrate it at all, but its pretty darn easy to use. You turn it on, stick it in the water and it gives you the PH almost instantly.So, they are a little more of a pain to use?

OTO?If a pH meter loses calibration and you don’t realize it it can lead you well astray. If you get pH readings you don’t expect you need to double check it with the OTO test.
OTO?
I think you mean pH reagent or calibration solution?
