Good morning Mr. Bond! Sorry just had to do itbond007069 said:How do you lower ORP reading, mine have crept up to 422, any my unit is not even on. Controlled by a Milkaukiee
thank
Before you try and lower your reading, clean your probe. When it gets even a little skim of crap on it, the readings will go up. I clean mine weekly, use a very soft toothbrush. And if that doesn't work, and you still need to lower your ORP reading, do a small water change. Mine always drops after I do one.
