Present size is not what minimum tank suggestion sizes are based on. There are multiple posts, almost daily, with this same basic story. Fish in a "too small tank" with Ich, MV or some health ailment. Too small equals stress. Stress equals lowered immune system. That leads to problems most of the time.
Leaving the DT fallow lets the Ich die off. It can not live without a host. Fish treated in QT will be Ich-free and will go back into an Ich- free tank. Not killing off the problem leaves it to come back. Big bucks have gone into research about this parasite, so they know what is effective. Read about it and learn how it works and you will see.
I've heard different fish stores talk about several treatments for Ich over the years. Fresh water dips, cleaner shrimps or wrasses, various snake oils, etc...then you read and learn that those do not work, but people see the spots disappear and figure their fish somehow was cured. The Ich returns down the road and they wonder why. I used to be one of those people, which is why I try to share and help others out.
