When doing water changes, make sure that you replace the salt at the same level. Although Clown loaches did fine with this treatment, Corys do not necessarily do well as I have lost some with this treatment. You should also be able to use many of the ich medications with the salt treatment, but be careful about your salt level since many times much of the ich medication is salt. This is supposedly very effective, but fortunately, I haven't had the need to try it. It's the stuff you make ice cream with.
Table salt is a tricky thing.
I just avoid it altogether, and don't recommend it to anyone else. Read the label. It can and will kill fish. However, I do know of people that have used it and killed their Clowns. AquaWeb Fish Resources Jeff Shafer All Rights Reserved.
