I'm in agreement with Doug.
Personally, I have seen white slime/film appear when ammonia present in a tank. I think that is a direct result from the ammonia, and is a bacterial film. I wouldn't change the temperature or salinity at this point...neither are at a point of causing damage. If I was in your position I would follow these steps:
Find a new home for the tang asap.
1. Do a 50% waterchange today, with water that has been mixing for at least 6 hours (in emergency), and matches the temperature and salinity of your tank.
2. Use Prime to neutralize the remaining ammonia. Add the tank's full dose to the water change water.
3. Do a 25% water change tomorrow.
4. Buy 30 lbs of live rock, and put it into a Rubbermaid container with a powerhead and a heater and allow it to cycle in the tub for several weeks. After the cycle is over you can add it all to the tank without worry.
See where you're at after that.
