Being its an lps coral the most obvious culprit to me is the lack of nitrate. Nutrients are what keeps corals nourished and when the tank is lacking them it opens the door to outbreaks of dinos.
A little extra feeding, more fish and less skimming are all ways to build up the levels but you're going to want to keep an eye on algae congregating and settle somewhere in between.

I would agree to nitrate but if its been like that for so long maybe it could be something else. Perhaps a pest?

Seams to be getting worse I stopped skimming and the brought my nitrate up to .8. So far I have lost 2 acros one large chalice and this moon favia. Now my candy cane is starting to show the same signs. I'm going to send out an icp oce they arrive I'm wondering since I haven't done a water change in 9 months if I'm deficient in something or is there I pest I should check for?

Nitrates going to .8 is still not much. Based off what information you shared and it happening to multiple types of coral I think the logic answer is still they been starving. Once an LPS starts starving it is often difficult to reverse the progression.

My only confusion is they been like this for months and growing fast

Off the top of my head I couldn't think of any pests that would result in all of them dying so maybe water parameters?

water change usually solves problems. I think not doing a water change for 9-month is the problem. chemical build-up or nutrient deficiency is happening.

Ok I sent out an icp in the mean time I'm seeing a new crustacean with my copepods is it a possible pest?

Bump. Had these too

Did they do any damage?
