Ozone?

[Chin_Lee]

i run ozone through my beckett skimmer. Its controlled by milwaukee ORP controller and I set mine around 420. I dont' run carbon for the ozone because my skimmer outputs to a separate chamber before overflowing into an area that is inhabited by animals. Ozone is supposed to be so unstable if it gets injected into a skimmer, there is really no possiblity that it will come out of the skimmer without the extra oxygen particle getting knocked off.
Ozone will make extruded plastic brittle in no time. I used to inject the ozone through a john guest fitting and within a week or two, that fitting will break if I apply any pressure to it.
Delbeek also spoke highly of it when talking about the equipment used in the Waikiki aquarium.
