Acan more like ACAN'T

OK I am really at a loss. I keep trying and keep failing.. I have a bunch of acan frags. They start off looking amazing, plump and juicy and stay that way then for no reason i can tell they start to shrivel up and die. Takes a few months but can't get them to recover after it starts. I have a bunch of corals in the tank and all do well. My Chalices are growing like weeds Zoas look great and all my frogspawns and torches and bubbles look healthy. I am just not able to keep my acans healthy. My water perams are really good. They are consistent
Salinity 1.025
alk - 9.6
CA - 420
MG - 1410
ph - 8.0
Nitrates 0.0

I test twice a week both no swings since i have been religious about water changes and testing. Lighting i have been using for a year I have LED lighting on a controller. Water temp is 80 all the time.

Here are some pics of how they look when they are happy in the tank and here is how they look now. It started to go down hill so I tried to move it to see if location was the issue.
Happy...

Unhappy

Here are how other corals looks in my tank currently.

 
Are you dosing anything to add calcium, like kalk in your ATO or 2-part? I've seen them do that from alk issues that clear up after a week or two after adding it into the ATO. How are you testing your salinity? I've seen them do that from high salinity and stopped once it got down to 1.023-4
 
I do dose Kent's part a and b. I use a Doser. I test with a refractometer. Checked calibration. I don't dose with anything else anymore I have and it spiked my nitrates in the past.
 
My acans love mysis shrimp. I even do some thawed brine shrimp in a pipette that I slowly dispense over the head. I have seen great results with that combo. I do once a week of each for a total of two weekly feedings.
