Personally, I don't use any medication on my dats. Recently when my heaters failed when I was away for the weekend and my tank was at 65 degrees and there was an ich breakout. I thought I was going to lose my dats but I treated with salt and raised the temp and I ended up saving all of my dats...but I lost two of my red-hump geos.
Just remember that when you increase the temp to treat make sure you are pumping a TON of air into the tank.
