ORP range?

300-400
I found this online. I just wondered if this was accurate for a reef tank?
"That middle ground is typically described as being between 200 and 500 mv. Most aquarium authors have recommended a range of 300-450 mV. Why? Mostly because the ocean often has ORP in this range, and because these authors have successfully operated aquaria in this range. "

A lot of variables play into it. Getting fresh O2 into the water helps keep it higher. I gained 35 points in a few hours when I swapped my BK double cone 150 skimmer out with a Vertex 180i. Ozone will make it jump even more. Again though, there a lot of variables. Seems odd, but mine drops when I do a water change.
