Hello I have a 40 gallon breeder and about two months ago I had a pretty bad case of ick that ended up taking 5 of my fish; 1 German blue ram, 1 African dwarf frog, and 3 Julian Corys. I treated it with bacteriashield and now that the fish are back to normal I want to add in some new fish. I did some research about fungal infections in fish and from most website they stated you need to completely disinfect the tank and get new plants and gravel which I’m willing to do because I was to re-aquascape it anyways. I’m mainly wondering how I should go about disinfecting, is this true (few websites said you didn’t have to), what disinfectant I should use that is safe, etc.
