hi i recantly had a major ich out brake in my main reef tank so i caught all the remainder fish and put into my qt they have been in there since may 20 i plan on puting them in the reef on aug first. but while in qt for the fist week they had no ich spots and i medicated with quick cure which says it effectively treats ick and other stuff. does this stuff really work and kill ick what i can't see. i really don't want to do hypo please help thank you.
