What happened with your Ick situation? I am experiencing the same problem right now. I have 13 Cardinal Tetras and 1 Corydoras Catfish and a severd Ick outbreak on the Cardinal Tetras. All I have tried so far is 1 tsp. salt per gallon with Tetra Lifeguard medication and increasing the temperature to 88 degrees. So far no deaths but I am wondering what to do next. Just treated for 1 day so far.
