Have you tried dropping salinity for, say, a month? Try dropping it, gently, to 1.019, for example, and see how it works. Leave it for a month and slowly raise it up.
BTW, ozone and uv aren't either or. You can run both, as I do. Running both in small amounts helps make the water crisp, so to speak, and helps the skimmer (rather than hinders it). But they won't control ich on their own.
What are your water quality measurements (e.g. ph, salinity)?
