I'm not sure why you're disinfecting and going through all of this? The fuzz is probably rotting food or an algae as everyone has previously stated. Fungus doesnt just pop up in a tank like that it has to have something to start with. You were the one who said that you may have overfed.
Someone has to point out to you that even if a diseased fish coming into your tank (because you added fish after we specifically suggested you not add any new fish to the tank until your tank is cycled) could have caused all of your fish to get sick and stressed and die....its more likely that they were stressed out already from high levels of ammonia and nitrites because your tank is still cycling then you stressed them out further by adding new fish and overstocking the tank which probably brought a disease in in addition to everything else.
I'm sorry if this sounds harsh, but you apparantly decided not to heed any of the comments made by myself and others in your previous threads, or lotus/seleya/nobody in THIS thread and just continue going on listening to what you want to hear. It gets increasingly frustrating for all of us to read this especially when you start a thread off by saying that you're not testing your water.
