Also, as far as aeration, I have a waterfall type HOB filter that's rated for 20 more gallons than my tank is, and two bubble-rods that span the whole 36 inches of the back wall of the tank. Hopefully that's enough aeration, which I also read is something important in fighting ich.
When I had to treat ich earlier this year (shipped fish from Peru came in the mail with it), I just used heat. I lost 2 of the 10 fish (neither of which could even swim on arrival, they were too far gone). The other 8 did just fine. Since keeping them calm for the acclimation meant no lights, the plants in the tank would have competed with the fish for the available oxygen. I had to add airstones driven by an air pump to their QT tank to help them though, as I only use sponge filters in my tanks. I've since bought a small HOB filter to keep on hand, as they do a much better job to aggitate the surface of the water, which is what you want.
