That’s a different product. Op is talking about something called. Non ich or something like thatI used ICH-X by Hakari, it didn't harm my bio-filter on my fresh tank. I don't know if it will harm salt bio-filter. Clean tank? As guess it could mean a QT or hospital tank, I medicated my whole fresh water tank, you don't want to do that on a reef tank though.
