By the way, thanks evil on the suggestion re: how much water to remove
Still some flashing going on, not as much. Still no other "visible" symptoms. However, I was wondering if it was the increase in the ammonia that was the cause (which is back to 0) is it possible that IF that is what was causing the irritation that it make take a couple of days for the flashing to stop? If you know what I mean, ammonia caused irritation, ammonia back to 0...but could take a couple of days for whatever nasties is did to the fish to "heal" so to speak??
