And what about spots, did you see them? Also, how long has it been since the ich has been gone?
Additionally, I have never said that the reef meds don't ever work. What I have said, is that they are not reliable. This means that putting meds into a tank is really a bad choice all around for the health of a tank, and that these reef meds, just do not have a good enough reliability factor when it comes to effectiveness.
If I treat a fish appropriately with hyposalinity, I am very sure that the fish is cured. If I treat a fish with a reef safe med, it may work, but it is just as likely not to work. To me, this is not good enough odds, Especially when the treatment could have long terms effects on my tank and it is likely not to work anyway.
Reefers need to keep the chemicals out of their tanks.
