Blue Hippo Tang keeps getting ich.

At this point your DT probably has ich in it.
Ich is like the flu in a way (except its a parasite), if your immune system is high even though there are germs everywhere you won't get sick, your immune system is down you'll get the flu. Same for ich-fish that are healthy with good immune systems will rarely get ich, stress, low immunity and the fish will get ich. Also ich can be inside gill covers and you'll never know its there.

If you are QT'ing, and treat for ich, once treatment cycle is done you should still keep it in QT for awhile so it can recuperate. The treatment is stressful and then moving directly will stress it even further. Let it regain strength and health first. Feed garlic enriched foods to boost immune system.
I also use the NS ich shield pellets during my QT process

Everyone has their own way to do things that work for them, so calling people or their methods dumb is just not okay.

Research has concluded that: Quote from Marine Ich - Myths and Facts "Fish always have MI. Untrue. In the wild they often show up as 30% infected."

As ich has a fish free stage-namely cysts which last 60-76 days on the substrate, it points to the fact that there are periods where fish are indeed ich free as its a parasite-not a disease.
