Help RBT dying

Ok I'm at my last straw I can't figure this out my tank is over a year old and I got my rose bubble tip over a year ago he was doing good even split into 3 like 7 months ago. Now all 3 are shriveled up and have been for weeks and looking almost dead and trying to move under rocks to die.

My water is fine and in normal readings.
75 gallon tank 29 gallon sump
Sg 1.026
Mag 1250 i know a little low but has dropped before with no change in tank life I normally add mag with water changes
Ph 8.0-8.1.
Alk about 11 will get to that in a min.
Po4 .08-.16 was running phos reactor
Ammonia 0
No3 10-15
Cal 420


My ph has never been above 8.0-8.1 even putting skimmer vent to outside. So I used a buffer to try and boost it. It never changed and my alk went over 15ppm and I did a 30% water change and got it back down. But now 3 weeks later my guys are still shriveled and very small and almost dead. Any ideas? One has the mouth starting to open up which I know that's almost dead. All other fish and animals are fine.

I have noticed my sea grass or long pollips which normally disappear at night are still staying long like during the day.

All other coals are fine my frogspawn looks a little bleached that's why I stopped the phos reactor. Over 2 water changes ago. Need help on this one......

And no it's not low ph it has always been low and they have done fine.
Po4 was .64 and I got it down
 
Yes I have been feeding all of them the last few weeks they will not eat since shriveled. I feed mysis, clam chunks, and silvers.

I have led lights exotic pan pro LEDs 12k whites I just unplugged the ones on there side to see if that helps. 12 hours off 12 on, Only thing that changed was my blue tang had ick so I moved a few rocks around and fresh water dipped him. Then put the rocks back. Strange thing is it's all 3 bubble tips that are shriveled
 
I would have to say no to the silversides. It's been maybe 3 months since I have them a silver. Mostly clam meat and the mysis
 
How often were you feeding them? Sometimes too much or too often can make them sick but it shouldn't happen to all three at once. Maybe you got a bad batch of salt mix?
 
BTA's often shrivel up to purge waste can take up to 3-5 days for it to do this. The only strange thing is that all 3 are doing this at once, so don't believe this is what is happening.
A BTA will split for one of two reasons.
To breed because its happy and thriving, will split and the split section will generally stay close to the mummy it split from and neither will start moving around the tank much at all because its happy with flow & light
OR
the BTA is stressed & feels it wont survive whatever is happening to it, it may start moving or walking around before it splits to increase its chance of survival. In the stressed case the new babies (as such) will move away from the danger area that the mummy is in (often mum moves away too)
When you say your BTA split, originally did it show signs of happy split (eg. stay together) or stress split ?
I def check all parameters because for all 3 to do this something has changed.
Have your changed out your globes recently ?
Have your changed your salt recently ?
Have your started to run phos remover ?
Or had a major drop in nitrates etc.
Sometimes major swings can upset these guys.
The general feel for this is
If their foot is a nice colour (generally pink) and they are still attached strongly to the rock they should hopefully recover.
If they are losing colour in their foot and not holding on as strongly as they should you know they are in trouble.
Can you see their feet at all ?
Before they shriveled up did you notice any gaping mouths at all ?
 
How many of those led fixtures do you have over your tank? If im not mistaken they aren't very powerful.
 
No they where all fine before they shriveled up. Only thing I did was run the phos reactor and dropped it from .64 to about .32. Ya I know they purge but it's been 3 weeks. They have moved some but mostly tried to go under rocks like to die lol. Will look at there feet tomorrow

I have 2 of the white led pros. And 2 blue and 1 blue magenta 5 total They are very bright. Not to confuse them with the stunners. Yes when it split into 3 all stayed in the same area and my gold stripe clowns love them.
 
No gaping mouths before they shriveled. Used to be as big as a baseball or softball. Now like a quarter . Last few days 1 had an open mouth but has closed it yesterday and walked a little

how long have they been under those lights ? Are they new lights ?
the phos drop is quite dramatic, shouldn't die but might well be sulking
 
The phos drop was over a few weeks. And the would shrivel up because of the drop? I thought they would like the drop since phos is bad for them

If it was over a few weeks then probably not, I got the impression it was over a few days. You know the old saying nothing happens quickly in a reef tank. lol
check their feet if you can see them.
