Hi all, I’ve occasionally had some false low PH tests, and can’t figure it out.
I always do Chlorine first, then PH. Sometimes when I do PH I get a super low read, dump it out, rinse and do it again then it is more in line where it should be.
The only thing Hong I can think of is that I’m not really rinsing the tube fully from the chlorine enough, I’d like to think I do, but is the chlorine test powder or drops have a history of skewing PH?
