When you start to think you are getting ready to add fish, then you can add a heater and gradually bring up to discus temperatures. Keep an eye on your nitrIte and nitrAte levels as at this point you should be adding ammonia and at the end of the day only show nitrAtes.
Maybe Sayid might be able to add to my thoughts, but I didn't have any problems by doing that way.
