I've been attempting to treat ich in my aquarium with heat and adding garlic to food. Today is day 14 of maintaining 86°f and the ich is still visiable. I've been doing 25% water changes every 2-3 days (typically done soon as the spots fall off). And the ich shows up... dissapears.... and returns every 4 days without fail. It's never much a spot or two per fish and not all fish affected. I'm at a loss what to do next. I don't want to medicate because it will stain my white sand. But will do what is necessary. I'm thinking I should either try aquarium salt or bump heat to 88°f. Perhaps both? I don't want to maintain this high temp too long. (It's been up past 83 for 3wks now, i struggled to maintain 86 in the beginning) Suggestions?
