Just a note, Prime will only detoxify the toxic part of your ammonia. It will not actually remove any ammonia from the tank. The bound up ammonia will still be in the tank (just not toxic) and it will still need to be eaten by the good bacteria. In your tank, what is your
pH? If it is 7 or below then there isn't enough of the ammonia that is toxic to hurt your fish. Just keep doing water changes to keep the level low and they will be fine. However, if your pH is 7.5 or higher then you need to keep that ammonia level at or below 0.5
PPM though water changes or use Prime to bind up the toxic part.
