Long story short, even Randy says ORP and what it means to the reef is not very clear. As long as it doesnt drop like a rock or shoot up like a rocket, it doesn't mean anything. If it does one of those things, it can mean something is wrong or possibly dead.

I shall keep an eye on it. I have noticed it does go up and down depending on the time of day but not a huge amount,Good safety measure.

Right, it well generally be the inverse of your ph. It will also drop a little after top off, or a water change, or dosing certain additives.

This I have noticed. So right now I’m dosing Kalk via ATO and PH goes up but ORP goes down in correlation with topping off.
