ORP and Ozone

[vanreefer]

For all thosse who are running O3 on their tanks what ORP value do you shoot for?
I have read that natural sea water has an ORP value of 350-450... I have not started running O3 into my tank yet as I just DIY'd an O3 reactor my ORP swings from 350-75 in the day time to 320-30 before the lights come on, I was just wondering where people shoot for as an optimum ORP?

Some interesting reading on the electrochemistry behind ORP
