Does anyone have any experience with these products and what did you think of them. I have no issues, but a fellow reefer had a clown with an infected eye and wasn't able to QT it and as a last minute either lose the fish [swimming on its side] ot try some melafix in his DT, he added some and the next day the fish is swimming and eating. It claims to be reef safe amd even cures flat worms on corals, has anyone used it on AEFW's?? THANKS
