Instead of Nuking the tank, clean it with hydrogen peroxide first, then rinse it out with water that you would use for the tank. Discard the water & wipe dry with a link free cloth. Wash any artificial plants & other decorations the same way. Live plants have to be treated with a bleach solution or tossed out.

After some research, I found out that Chytrid is a common fungus with fresh water species. The highest temperature it tolerates is 76 degrees F. I keep my tank at 78-80 degrees F (ADFs can tolerate temperatures to 82 degrees F) & it seems to keep it at bay. Keeping the tank clean is the next priority. I do a "spot" clean daily to remove recent debris (especially eggs) & do a 30% water change weekly. Also, make sure you change your filter regularly, so it doesn't circulate back into the tank.

Good luck!
