Maybe you guys can see something I don't. But I can't grow any acropora in this spot. Already had like 6 frags that stn. In this area. Will take like 3 month and it will die. Other side of the tank, no problem. Mixed reef tank.

It wouldn't kill anything immediately. Looks like other acros and sps do fine so it seems your water is ok. If it's not a shadowing issue or something close to it stinging it.....would lead me to flow next.

It may be that softie that is just behind the spot. Many softies give off chemicals to defend themselves and if there is no flow the chemicals may be sitting in that area. Check allelopathy.
 
Looks like the trouble spot is lower than where your thriving acropora are. It could be a lower light intensity spot, at least enough that small new frags can’t take hold there. Maybe try a large frag from one of your thriving acroporas. Or try a green Slimer or Acropora carduus (eg red dragon) or some known lower light acropora.

Ill just reply to all in this one post. So this is spot, with in foot of that area I got large sps corals growing pretty large sizes but frags of across are dieing slowly only in this area colored in red.
It is not dark in that area. I have MH lights in this tank, with par in 160 range at sandbed. 300+ at that level of tank.
Someone mention about softies, closest I got is gonipora about 10" in front of that area. Everything else is sps surrounding that spot.

Dead zones culminated with chemical warfare, that could be a pooling spot for all the nasties. I’d throw another wave maker. Why do you have to have an acro in that spot?
Also the Cyphastrea on back wall is bad butt!
 
Have you checked the area in the middle of the night? I had the same exact thing happening on only one rock in the whole system. Long story short 20240221_000629.jpg now there's 3 mini colonies on that rock.

Pest is a big probability. I never quarantined any corals, and I got them from so many different stores, other reefers....

Finally decided on fixing my flow issue, time will tell it flow was my problem.
After patiently waiting to find a used SeaSweep. I rigged it to turn from 90* to only about 45* placed it right in the center with pumps aiming in low flow spots. Put 2 most powerful jebao pumps avaliable. So far i like it. Exept the mess it makes from stirring the sand here is a short video of it.
