Could it be a circulation issue? Is 12X turnover enough for acros?

According to most i've asked, it is.

Sounds like RTN :cry:

RTN
 

The duration it takes for the coral to die is pretty quick. I'm fairly new to the hobby. Can someone explain to me what RTN is and if there's anything I can do to help.

It's not RTN. RTN is obvious when it happens. The tissue almost floats away from the skeleton very quickly. You can lose a whole colony in hours or less!!
Jelly is something I would use as a search parameter in Eric Borneman's forum at RC.

I've lost a couple of the corals in a matter of a couple hours.

have ytou posted anything to eric's forum on RC?

Nope, why?

Eric Borneman is probably the best resource for determining what type of "affliction" the acros have. And how to treat it. I always post to his forum for things like this.

yifan917 got many nice sps that I saw. He maintained excellent water quality.

It may be something to do with your water quality.
