I was under the impression (from my experience with hypo) that the
SG had to be lower than that to stop the cycle. I brought mine down to 1.009 and never let it get higher than 1.010.
Sorry for your losses. Adding selcon, garlic and fresh ground ginger to your fish feedings will help boost their immune systems though. That might give them a leg up while you battle ich.
Good luck.
