Acros peeling from top down

So I got back from vacation and noticed that one of my green acros had started to bleach from the tips down. I checked all the parameters everything's was normal and I also had a dosing pump set up to maintain calcium, alk, and nopox to control nitrates. It seems there had been no changes aside from one water change halfway through the vacation. A few days ago I noticed the same thing is happening to my purple acro who was looking ok since I got back. Both theses corals were doing great and had entrusted onto the rock before I left. My other sps (various montis) are doing great and growing. If anyone knows what causes them to slowly peel from the top down please let me know. Thx
 
Will you list all your parameters so we can see what normal is? Also any pictures are very valuable.

Parameters seem normal. Any change in lighting? Have you tried adding a Polyfilter in case some sort of chemical got into your system?
 
How long have you had those pieces?
It's tough to see the pics in my phone.. is that monti reaching the acro or is it just the angle?
Stressed acros can just up and rtn when another coral comes along and burns it. Normally a healthy acro would probably burn the monti but those acros do not look like they have been healthy for a while. Again, though tough to see on my phone
In my experience, acros that just give up the ghost like that have had issues for a long time and have finally succumbed..

I've had these two for more than four months and they have been very healthy up until I got back from my trip. Before I left they had encrusted onto the rock with full PE and were continuing to grow. No sign of bad health. 2 weeks in the trip they still looked great. So something must've happened in the last 2 weeks possibly after the LFS people did the waterchange.

The Monti has grown around the acros without touching them so there is no physical signs that the Monti is bothering them. The bleaching has been pretty slow/constant for the past month.
 
Well, bleaching from the top down is generally related to too strong of lighting. What kind of lighting are you using, what intensity and for how long?

Ok I don't know if you read my earlier post but the acros were in a very healthy condition until now and we're growing. There's no way the light is the issue if they were healthy until recently and the lights haven't been changed. Something happened while I was away. If u have to know I'm using the AI prime for 10hrs a day.

I did yes, and no I don't have to know. We're trying to help you, remotely, from a couple limited quality photos and limited info on your tank. We're doing our best with what we've been given and offering the best suggestions we can.

Since you know it's not your lights and you know it's not any type of chemical leached into the water, then next suggestion would be bug inspection. Pull a couple out and get them under a magnifying glass. Or if you have a dslr with a macro lens, you can try that route to get a close up.

Sorry about that but sometimes people on here don't really care and just mess around with me while I'm trying to find and answer. I'll check tonight and see if I find something.
 
One other possibility is something that happened during your vacation such as a power outage. Do you run an Apex? Are you able to review your graphs to determine if there were any power outages or temperature drops (or spikes this time of year).

I had someone there watching the tank so I don't think there was an outage (that we know of). All of the parameters were stable (I don't have an apex) so I'm wondering if something regarding the water change/maintenance the lfs did may have caused this.

Since this was triggered by something that happened weeks ago why is my purple acro just now starting to show signs? I know there can be a delayed response but can it take this long? If this is the case wouldn't both of them have been in the same condition when I got back or does it depend on the individual coral?
 
Are the bottoms alive on those pieces? From the pics, it's kind of hard to tell, but it looks like the bottom of them are all skeleton and only the top part just died recently.

Also, the LFS people that changed out the water, have they been using the same salt and mixed to the same salinity the entire time?

The bottoms are alive because they have been dying from the tips down.

Yes the salt they are using is the same as what I'm using. I'm not really sure what else they did that could have irritated them if that's what happened
