i've got ick in my 75g cichlid tank right now. i've been ising paragard. it's suppose to be really good. they say to treat for 14 days. after 3 days, all of the symptoms were gone. i kept using it like they said though. on day 12, two of my fish started showing signs of it again. i've started the treatment over again. i have invreased the temp to 88 this time. maybe between the two, it will finally go away.
