Hello, I have a 70 gallon tank with live rock, shrimp, feather duster, and four firefish. Ammonia 0, Nitrite 0, and ph 8.4.

I noticed ich a few days ago. I have been treating with Chem-marine stop parasites, and Coral Vital. It been two days and its not getting better. I have had saltwater for 10 years(before I had groupers and Lionfish) and never had ich. What do you have to do to get rid of it? In freshwater all you do is dump Maracide in and do water changes. In saltwater it seems like ich is bulletproof.

Please help.

Thanks.
