I'm no expert, however, I've been doing ALOT of reading and research from fellow reefers and it sounds like you're on a good path to begin. Set your controller to 380 and raise your ORP by about 20 each day until you reach that point. Bring your riser tube up to where you're producing a dark skim and adjust aqs needed(kind of a re-break-in) period... good luck and keep us posted as to the changes. My meter now reads 315(without ozone), but will be set at 380 when I get my new ozone generator.
