I need more bioload lol.

Any chance the probe needs calibration? Not an expert on ORP but that seems rather high.

I cleaned it and it dropped down to 425. I have a backup probe that was brand new. I tried it and its numbers were very similar, so it is not likely a calibration issue.

I just recently upgraded from a 50 gallon total volume tank to a 110 total volume, so there is a lot of new fresh saltwater in it. My guess is there isnt much in the water to start with.

Then it does seem you need more poopers in that system
