What do you think the smallest tank size is that I could use to do the ttm on them? The Angel is 3.5 inches, Gramma 3 inches ,Blenny 3 inches and one clown is 3 inches the other is 1.5 inches thanks.
For ich, the quickest, easiest and most effective treatment is tank transfer. However your display tank must remain fallow for 12 weeks.
What did you do during the four weeks of QT? Did you just observe for ich or did you treat actively?
While four weeks of active QT is chancy, the chance that ich can be eradicated within 4 weeks of active treatment is not low, just not high enough.
I don't like TT per se but this is a teaser here. This is because you have to wait for the fallow period in the DT. What are you going to do after TT and wait for 12 weeks in the DT.
You need to support you fish for the fallow period. How?
I suggest that you treat this in two stages.
First is to prevent your fish from dying from heavy enough ich infestation. Light infestation is harmless to fish.
You can treat your fish briefly to prevent them from dying and then return them to ich infested DT.
Meanwhile, you cycle ASAP in a separate container in preparation for eradication of ich. Under ideal condition, a cycle is good to go in 21 days (a little less if the setup is wet-dry type).
The intrinsic limitation of TT is further illustrated here--a teaser solution.
If you can, this is what I would do: Get two 10g tanks and do the tt (petco sometimes has them on sale for like $10 each, if not sometimes they still honor it, just ask). I would also setup and cycle the 72g and transfer the fish to it after the tt is complete. Keep them in the 72g for the 12 week fallow period of your main tank. keep in mind that you would also need at least two sets of equipment to do the tt successfully. I usually do the tt a couple of more times then the recommended just to be on the safe side.

Why do you think a light infestation of ich is not harmful and what method of eradication are you suggesting he use?
Light infestation of ich is better than ammonia and no food for the duration. Light infestation does not kill fish if corrected in time.
Eradication of ich without cycled medium in QT is difficult to do safely. You need 12 weeks of fishlessness in DT so you need cycled medium in QT for 12 weeks.
Hence the two-stage solution I recommend.
First treat so that no obvious infestation is seen, then return to DT. Watch closely repeat if necessary. how soon? what kind of treatment? If before 12 weeks can the fish be re-infected?
Second, at the same time cycle ASAP some medium in another container (can be a five-gallon bucket). After cycle, use the medium in QT for eradication.

At any rate, use Amquel or Prime for only three weeks if you want to. I am sure that one will get nervous and do WC during such time--a lot of work.
Cycling ASAP now is the only wise thing to do--necessary.
The difference is 9 weeks vs 12 weeks of easy maintenance with cycled medium. 12 weeks of Amquel/Prime and WC is simply foolish.
Cycling for QT is extremely easy; some still want to shun it for inferior alternatives.
