actually your temp, is high as well. you don't want to speed up the cycle of ich you want to slow it down IMO. this way the fishes metabolism slows as well and there not stressed and when you heat up the tank and speed up the fish they eat more and pollute more. soak your food in garlic extraced as mentioned and SELCON. cleaner shrimp might help as well as cleaner gobies not wrasses. wrasses[cleaner] should never be purchased[whole bunch of reason]
