Orp really low

[dylanst.onge]

So I just set up an apex about a week and a half ago and it is showing my orp being about 185 but from researching online it should be up by 300s everything seems pretty good in the tank though I was just curious what others are running at?

The “should be” comment is incorrect. There’s no evidence that specific readings are desirable, as long as you are not adding oxidizers. I’d personally ignore ORP readings except as a curiosity, at least until you become very focused on chemistry, or begin to add oxidizers such as ozone.

There’s an article of mine in ORP in the articles link at the top of this forum that has a ton more info.
