what fish are you feeding it to?
i usually do general cure (praziquantel and metronidazole) and focus, i've never added kanaplex or garlic. they usually eat it without big issues. what kind of food are you soaking it in? why are you doing kanaplex with it? i tried feeding antibiotics, i think i used spectrogram, when i got velvet and was doing copper, but idk how much it worked as i lost several fish to a bacterial issue post copper treatment
my last bacterial issue i ran into, i did cipro baths and i can't recommend those enough. it was gentle on the fish and worked great. not really that much work either, but hard to catch a fish daily for a week if not in a qt tank
