I have a 125g tank with a tiger oscar, 2 small bala sharks, a small pictus cat, 5 tiger barbs, a pleco, and an african cichlid in it. My problem is that I introduced a green severum about two days ago and this morning I noticed that it has ich. It was fine last night but this morning it is covered in the stuff. I quarantined the severum and have begun treatment for it. I did a cleaning on the 125g and have started to try and raise the temp in it to at least 86. For some reason I can't get it above 80 right now. I was concerned for the pleco and the pictus cat so I bought some aquarium salt and disolved a cup of it in water and slowly added that to the tank. Is this amount of salt going to be enough to treat the ich in the 125g?
