A list of methods to treat/QT for marine ich based on order of my preference:
1. Tank transfer
2. Copper
3. Hypo
4. Chloroquine Phosphate
and yes, I tried them all.
There are pros and cons for each method. Make sure you read them all (not only this site but some other sites as well) before you pick one. Above all, understand the life cycle of marine ich is very important regardless which method you pick.
Good luck.
