Well, after losing most of my fish in a power outage, I QT the new Chucky in copper...after 2 weeks my patience ran out and my stupidity came up and I put him in DT...been there 2 days, all seems well except he has one white spot right on his lip...last time you thought it may be a sand spec...if it is ich, is Quick Ich safe and effective in a reef or will it do more harm than good...I'm sure that you think, "if these guys don't listen, why do I bother"...sorry...I suppose I can remove him, but of course, this would be easier...Thanks...I'll listen this time...Ken
