Parameters ? Lights ? How long has it been in your tank?

It is kind of hard to tell from your photo but it appears the Acan still has tissue or is it just the lighting? Agreed that we need more info on your aquarium before being able to diagnose the problem

To clear up moving them i mean they were flourishing in the same spot a couple days ago but i moved them over like 4 inches a couple days ago to make room for pulsing xenia

is it possible that it got stung by a neighboring coral? GSP are one of the most bulletproof corals so if that did not make it there must have been something seriously that went wrong

The gsp i think died from to much light i put it up on the rock work should have been down further it never adjusted well plus i handled ot a little too rough first go at gsp il do a full round of tests when i get home but i think with everything else thriving it wouldnt be water parameters im leaning towards a pest of some sort but could be wrong or lighting i think also could be thr problem as in too much

Large water changes should only be peformed if you have a good baseline of parameters and needing to correct dire issues.
I would advise listing the following parameters and letting us take a stab at it before putting another nail in your tanks coffin.

Salinity (measured by refracto at a minimum)
Temp
Ph
Cal
Mag
Alk
Phosphate
Nitrate

Is your RODI system discharging 0ppm water?

These parameters alone will help us rule out most water issues aside from you doing an ICP analysis for any other contaminants.

If you think its lighting thats too bright....you can reduce the output by half and slowly raise it 5% a day until at your target. A lot of coral actually dies from not enough light coupled with the inadequate enviornment for them to be able to photosynthesize.
