Established tang keeps attacking new powder blue tang, should I put the yt in the sump for a couple days right now I put a separator in the middle of the tank it’s been 3 days of fighting

Put a couple mirrors on your tank so they fight themselves and they normally chill..

You'll need more than a few days of isolation to alleviate aggression. I had to leave my coral beauty angel in a quarantine box for 2 weeks because she wouldn't leave my new yellow tang alone. Once released, aggression was gone.

Then maybe add a rock or two

you want to put the aggressive fish in isolation to let the new fish get comfortable and establish territory. 2 weeks may be overkill, but it was such a pain to catch the fish that i didn't want to have to do it twice...

Either one could work. I have no science here, just logic, but sump would allow him to "forget" about his previous territory which is good, but the acclimation box could help him get accustomed to the new fish, which is also good. Dealer's choice from my perspective, I can say I've had luck with the in-tank box though. Not sure how big your tang is, but you also don't want to jam a giant tang in a tiny box, so if that's the case maybe sump.

Gotta be in the display or it’s pointless.. you can just put the yellow tang in time out in the sump if you want but most likely won’t change his tude.. it won’t be long and that powder blue will most likely destroy your yellow tang lol..

Powder blues are notorious punks and will run your tank in no time.. do you plan on adding other tangs at any point? If so now would be the time and let them pick the pecking order and distribute the aggression amongst each other… I’d say once that powder is established it’s gonna be hard to add any tangs or even other fish. Not always the case but mostly is with a powder… most people recommend the powder to be the last fish in the tank.

How big was the mirror? It needs to be a decent size hand mirror thats larger than the fish so they can see all of the body. You can try a second mirror. I have had to use two mirrors before. You might be better off moving the existing tang to the sump or another tank for a week or so and then try moving back with old tang in an acclimation box for a week or so.

What is the level of aggression? If it’s just a little bit of nips off the top of the dorsal fins, I’d just not step in and over feed for now with keeping mirrors up. Only resort to removing a fish if it becomes a threat to their health.
I introduced 3 yellow tangs with a purple tang, and at first there was merely quick chasing, but a month into it it turned to fins being chewed. If I ever saw the fins get damaged to close to half way gone, or actual stabbing with their spikes, I would have stepped in. After about 2-3 weeks it died down. There’s still occasional nipping every few days, but even at the worst of it the fins grew back then next day or two.
Now I actually see some of my yellows try to chase the purple time to time lol

Get some cheap tank ornaments, big enough that the fish can explore then, and throw them around the tank. Make a defendable fort for the tang getting hassled. Triple the food supply and feed from all different areas, plus the mirrors. This is what I do. You might have to repeat this from time to time.
If you can catch the jerk tang... you can certainly put it in isolation for awhile. I have a jerk YT like that but I can't catch him now when he acts up.
