My puffer and purple tang came down with ich in my FOWLR 120 gal tank. My hospital tank is only a 29 gal and it wont hold all my fish. Has any 1 treated ich with soaking food in seachem's metronidazole, focus and garlic? Seachem claims it works. I was also wondering if any 1 has any experience with fishvets product called Equlibrium no ich marine. Its supposed to be biodegradeable and reef safe, degrading from your system in 5 days. If none of these seem like viable options then I will try seachems cupramine. Its supposed to be less toxic to fish and removable with carbon and will not adhere to your substate. Any thoughts on these treatments? I have already begun freshwater dips.
