I to have problems keeping my ORP up.
I have a 40breeder/20sump with a Redsea 200mg, If I have redsea turned to 100% my unit runs 24/7 just to maintain an ORP in the Mid 300's
Even after charging air drier (what a pain) I don't see much improvement.
I currently am feeding it into my skimmer, I wonder if I use an ozone reactor if I would have longer contact time and get better results?
Also what type of air pumps are people using? I was told that Ozone is only reactive for a few seconds, I wonder if using to slow of air pump would limit the amount of actual ozone being delivered to the skimmer?

mnestroy, as you can read above, I have had a challenge keeping orp levels much higher than 300mv at 100% using an ozotech unit.
I have a coralife luft pump on order, which provides 7psi of pressure, and is marketed as an air pump specifically for this application. My current pump only provides 2psi, and I suspect that this is limiting my ozone injection.
Perhaps you should get one of the luft pumps also. . .
Peace.

mnestroy,
The mid-300's is just fine for your ORP, particularly if you're keeping softies.
As you well know ORP depends on a variety of factors and ozone is not a cure-all. Some other things you can keep an eye on is skimmer effectiveness and sizing, reducing the waste load, adding a refugium, etc.
I'm using a large MTC ozone reactor which is working well for me and it would be hard to imagine anything working much better.
If you are feeding the ozone into your skimmer venturi input the amount of pressure generated by a pump doesn't come into play because there is already a suction. Without knowing the airflow you are currently running through your ozone generator and what skimmer you are running it is impossible for us to give you much feedback.
It sounds to me like you are doing fine.
What kind of ORP readings were you getting without ozone?
BTW - calibration can always be an issue too.

I'm really thinking that the Red Sea units are junk.
I run a sanders 50mg unit, on 100g of water, I run it at about 10-20% strength, and it runs roughly 20% of the time, to keep my ORP in the 380 range. I run it through my skimmer (which has some white PVC).

Well I donno how they compare to sanders, but I know first hand the Gen-x Units are Junk! and are falsely advertised. See below thread

I don't have any first hand experience with the Red Sea units but that might be part of the issue.
I bit the bullet and purchased and Sander and it is working well for me.
What method is the Red Sea using to generate ozone? UV keeps coming to mind. If that is the case and the unit has seen some use I think that with UV systems you might have to do some maintenance.
Paul
I'm fairly certain Red Sea is using corona discharge and not UV. I opened mine up in order to add a relay that closes when the unit is active. I could see that the air connections pass thru some sort of chamber that produced a rapid, soft clicking noise when the indicator was on, like there was sparking going on inside it.
