Just wondering what an optimum ORP is for a reef tank. What is your tank's ORP?

mine runs around 300 right now, it drops to about 260 just after feeding the tank and the highest it has been is 350 when i was really keeping up with my small water changes twice a week. this is without ozone or a uv sterilizer.
