I'd get a new filter cartrage as well, if you can. Maracide works great, by the way. At least in my experience.
You'll want to turn the heat up while the treatment is in, I'd say 85. My angels where tropics and we had to keep them at 85 for a couple days. 2 max. It helps kill the parasites And it won't cleanr up over night, expect 2-4 days. Oh and the plant has to go. Even if it didn't CAUSE the ICH, it'll have the ICH on it, and you can't really clean a plant. I guess you could leave it in a quarentine tank with treated water for a week, but I wouldn't risk it.
