I bought an American Marine
ORP meter. It did not come with calibration fluid (it's coming in from the store) However, in the American Marine instructions it says that you do not need to calibrate so I am a little confused there.
Anyway all that a side I get a reading of 285 on my Predator
FOWLR tank. From what I have read
ORP meters are like an overall guage of knowing the system stablity. Is there some sort of guide line as to where and when the panic
affect should kick in. Like uh oh it's 200 time to clean it or something?? Do you need to calibrate these monitors or am I missing something.
SomethingFishy here.......
