If you turn up your heat to 86 you don't need meds. If you want to use the med's then follow their directions and don't do a WC until the meds say but this is going to expose your fish to very high ammonia and nitrites which is not good. So IMO stop the meds, use the rule of doing a WC if ammonia and or nitrites rise above .25ppm to protect your fish from ammonia and nitrite poisoning even if you have to do a daily WC. The heat will kill all the ich and will aid in speeding up your BB growth.
