What brand of calibration fluid do you guys use for your tds meter? Where do you get it from?
My tds shows in the 300ish range coming in and o going out, but I haven't ever calibrated it.
I'm not showing any signs of bad water etc,
How far out of cal was every one's tds meter when they received it?
thanks in advance,
