In a non ovestocked tank, raising the temperature, adding air stones
and using the medication per the instructions should work. I've
heard there are some pretty tough strains of ich going around that this might not work with.
One of my loach tanks is pretty heavily stocked and despite my best efforts I could not get rid of ich. I fought it for 2 weeks with the battle
ending in a draw until i added a UV steralizer. Within one week visable
ich was gone but I ran it for another week to be sure. I've only had
to use the UV light twice but it worked like a champ both times. no
need for medication
All of my kubs and sids had it but none of my bolivian rams ever got it.
I didnt loose a single fish either time.
