Ich is not visible to the naked eye. The white spots on decor and equipment is not ich. The white spots that you see on the fish is where the fish's slime coat is reacting to the ich. To preserve the cycle I would treat with heat like I mentioned above. Ich will not survive 90f.
It has been found that Ich does not infect new fish at 29.4°C/85°F (Johnson, 1976), stops reproducing at 30°C/86°F (Dr. Nick St. Erne, DVM, pers. comm.), and dies at 32°C/89.5°F (Meyer, 1984), 
You won't need to clean everything with heat but it wouldn't hurt to do a good substrate clean.
The need for salt in a healthy tank is a very divided topic. IMHO
it is not needed. I suggest you do some research before deciding before or against dosing salt to a heathy tank.
