Stubborn Ich - Second Treatment Failed!

Double posting this since it doesn't seem to be getting much action in the emergency section
 
I have ich in my tank and I can't seem to get rid of it.  I've been dealing with it for about 1.5 weeks and it is still hanging around.  
 
The tank is at 86 F and 20 gallons.  Ammonia and nitrite are both zero.  
 
I first treated with Super Ich Cure (active ingredient Malachite Green and Nitrofurazone).  I used a half dose as the package recommended because I have a catfish and two small clown loaches (the third one did not make it).  The box said add one dose on day one, a second dose on day three then water change on day 5 water change and carbon.
 
Day 5 -  I still had ich, so did a water change then added another dose.  
 
Day 7 - More ich spots appearing, switched to Coppersafe (active ingredient - chelated copper sulfate). The box said no need to raise the temp, so I started turning it back to normal, decreased to 84.
 
Day 8-10 Out of town.  Temp stayed at 84 since I was out of town.
 
Day 11 - Came home, and the clown loaches look horrible!  Much worse than when I left and even more than before.  The temp is back to 86.
 
I know I can't do salt. Anyone know anything else I can try?  I'm getting desperate!

is it a planted tank?

something that has worked great for me with ich is me raising the temp to about 83 or 85 degrees and dosing with lifeguard and kordons ich attack. I only treat in my quarantine though that has no plants it was safe with the scaless guys like the loaches the ich cured in about a week ..there was a time that i tried coppersafe and it didnt work at all so they got worse and i went back to the lieguard and ich attack together and the ich cleared wthin 4 days. They are safe to use together havent tried it with invertebrates though. just make sure you do constant water changes at least once a week. I guarantee you it will work. It worked for me at least.


As for my main tank the 55 gallon I also treated it for about a week with the ich attack to make sure that any little ich that might be in there can be killed but none of my other fish got it

I've not treated ich with these types of fish... but I recently had a really bad case of ich as well and I found the temperature made the biggest difference in the end. I had to raise mine to nearly 90 for a week while treating and being sure to have airstones running.
