Doesn't quick cure have methylene blue already? If you're using a treatment, I'd recommend refraining from doing too much too soon. I'd use a half dose to start with and be careful dropping your salinity too fast. If your ich is subdued and there aren't too may spots, I'd leave the salinity alone.
If it makes you feel better, I don't do anything with my fish and just feed them more, improve the water quality, and turn up the temp a couple degrees. My Butterfly and Tang had minor ich for 2 months in my SPS tank and that was 2 years ago. They're ich free today.
