Help with canes and euphyllia flesh recession

[itelshot]

I did a 3 day blackout to finish off the dino and kept it under blue light only for weeks. They were bought a month before the blackout. Photos were taken yesterday. The problem is as follows: slipped tissue from the skeleton in canes, in euphilia seems to be too. Can this be due to changes in lighting? 2 people have already told me that similar holes as in canes say that something eats them. On the photo you can see brown planaria in canes skeletons (yesterday I bathed them both in lugol).
I returned normal lighting also yesterday, now at night cane again began to open their tentacles for night hunting.
I have no fish yet, the aquarium is quite mature and old, the rest of the corals are normal, some harmful worms or similar should not be (I always immediately learn about the creature if I notice something new). Night suddenly shining a flashlight also do not notice anyone.
What can it be? Maybe it was those planaria? It seems to be those with sharp wings, which are said to be harmless.
Phosphates and nitrates are dosed. Osmosis 0. Phosphates every day add +0.02 (absorbed by stones). Nitrates keep 10.

Night photo now

Healthy ones before blackout a month ago

both lighting and flow can cause this sort of recession. Have personal experience with candycanes. If you blast them with too much light or flow, they will recede. With light, they can acclimate over time, but when it comes to flow, getting blasted can be a death sentence if not rectified. No experience with coral pests, so cannot opine there.

this is tissue loss/recession and likely due to too much light o water flow. Assure phos is not elevated, salinity not low and no nearby coral which may sting it especially euphyllia
These are resilient coral and often dont suffer this issue

The current should be moderate, the light is probably even a little under-light with Jebao AL-90 for 200 liters. The tests will be done again now and I will tell you.

@vetteguy53081 Ok, will try make less light first BUT IT STARTED WHEN THERE WAS ONLY BLUES, HM, but i heard once exactly them in this light can burn corals. How high is posibillity to lose those?

Theyre tough coral. Furnish moderate light and water flow

How fast it can recover?

 

[vetteguy53081]

How fast it can recover?

Will depend on tank parameters and health of the specimen. Feed them mysis shrimp

Update @vetteguy53081 @TX_REEF
: I reduced the current on my two jebao mlw-20 to the possible minimum 30%, and also made less light and moved them to quieter corners, but they are still not better. On canes the fabric has slipped even more, holes have appeared near the crown peaks. Euphilia is still deflated. Predator-eaters I still did not notice. Except that on the bare skeletons, as I have already mentioned, planaria sit on them

Lighting makes it hard to clearly see but assure:
Salinity has not dropped or false
All is not elevated
Calcium is not low
Phosphate not high (above .15)
Any tiny grey bugs on them

What bugs are u talking aspecially?
Ph4 is posed, salinity is 35ppt (regullary calibrated).
Calcium: I don't have a test for it, but I use red sea coral pro salt. I haven't done any changes for a long time (about 4 months), the aquarium receives osmosis 0. Of the ops I only have not big duncans and these 2 newbies for 200+ liters. Could the calcium have run out?

Hi, I have a theory. Overall nothing has changed, maybe even got worse with these two lps. The dino's I've kinda got a handle on. I think these bubbles on the top in the most lighted areas are cyano? In the microscope the dinos looked not transparent and several times bigger. There seems to be no "slime" threads either, just bubbles like these. Maybe cyano somehow can also depress them, although it seems to be more close to the surface.
I haven't done a change for quite a long time, the salt will arrive only in the new week, I hope after a new change they will be better, because I don't know what else could be wrong.

I've noticed that they starting to look better when i dip them in lugole. Here is creatures that felt off after dipping, are there"grey bugs" you were talking about?

These are pods and the darker one ostracods called grass shrimp which are overall safe, just multiples in numbers

Good. Idk what's happening, hope i will make water change soon and they will get well, maybe take from it what they lack of, cause salt finally arrived to the store

Conclusion: lugole night few days dip, flow pump (Jebao MLW-20) rate reduction from 45 to minimum 30% (random regime program) and TIME. One of the folowing or mix of them, helped canes and euphyllia to start getting their tissue back.
Possible reasons: to high flow (it wasnt to high for another old corals), some sort or infection after new tank stress and 3 day blackout.
