Definitely check out the links other people posted, Chaz at ElevateShrimp seems to be incredibly knowledgeable about the issue.
I actually received a shrimp with ellobiopsis several months ago. I did nightly salt + Paraguard dips and dosed the quarantine "tank" with metronidazole every day for roughly two weeks before I got lazy. At that point, all signs of ellobiopsis had disappeared. I made him live in the quarantine tank for another 3 weeks with a bubbler and some java moss to make sure I didn't see it come back before moving him to the main tank. Since then, no one else has got it so it seemed like a successful treatment.
I'm attaching the treatment I used, although I went the extra mile and added the metronidazole.
