High ORP

[baloutang]

Is there anything bad about having your system run with a high ORP? Mine is near 481 even though my controller is dialed down to below 300. I've doubled check the calibration on the controller and it's correct. I've been running ozone for about a month
I have quite a few fish and it's well stocked with coral. I've not done a water change in 3 weeks (I typically do it every 2 weeks). My water is very clear, but my concern is that the ozone may be stripping out too much gunk as my coral growth is very slow.
Any suggestions?

I really doubt your ORP is 481 without injecting ozone.

I believe your probe may be bad or you are somehow injecting ozone without knowing it. :(

I would unplug the ozone generator and see if it starts to fall. You should see this in a matter of hours. :)
