Raising the temp slowly along with treatment helps to speed the life cycle of the ich parasite. Usually if you raise the temp in the tank 2 degrees per day until you reach 86 degrees F (and keep it that way for at least 7 days) that in itself can get rid of the parasite. The meds and/or salt just speed things along more if you add them along with the temp raising.
I agree that the tank is cycling and that probably made your fish stressed and more suseptible to the parasite. What a lot of people don't know is that ich is always in the water source. A healthy fish is usually tough enough to resist the parasite. It is when something isn't right with the fish that it falls victim to the parasite. I can atest to this personally. My friend had a fish that she was growing out and when it out grew its tank--but she hadn't moved it yet--it contracted ich. She hadn't added any new fish in 2 years and the only thing that was different was the fish had outgrown its tank and was no longer happy. Adding new fish can cause an ich outbreak because the addition can stress out your original fish.
Just a little bit of info. I hope that your next attempt works out better!
