Freshwater ick is not saltwater ich. You need to do quarantine with a copper treatment along with leaving the display fallow for 6-8 weeks so the ich in the sandbed can finish its life cycle and die off.

I'm using ick away but a friend just told me to turn the heat up and leave it alone as if it was a Freshwater.

The heat thing only works with freshwater ich. Saltwater ich looks similar and has a similar life cycle as freshwater ich, but the similarities pretty much end there. Studies show that kill kill saltwater ich with heat you'd have to get the temp up high enough to kill everything else in the tank as well.
