Above remarks is why I suggest all should use a QT and not for just a week or two, but anywhere from 6-8 weeks. And if treatment was needed for that fish in your QT, then it should remain there for even a longer time period. So ich only gets in your tank through any live stock you buy, so do use a QT.
