Yes: no carbon, crank the temps to 90* and add TONS of surface agitation to ensure sufficient aeration.
The purpose of the raised temperature is that it speeds up the metabolism of the parasite, causing it to drop out of the fish quicker. The whole goal is to get it to go through the three phases of its life where it cannot be harmed by medicines more quickly, so that it can be treated. It is only vulnerable in the free swimming stage, and it is vulnerable to aquarium salt (among other things). By keeping your temps low (relatively), you're lengthening the life cycle of the parasite and causing them to stay on your fish longer, causing more damage to the host.
