Euphyllia dying

newreef_sb · Oct 13, 2023

Does anyone have any idea why my Euphyllia is dying? We have slowly over the last month. Just when we think it's passed, another one is gone.
This morning I woke up and our $300 3 head dragon soul is completely dead. They are just there one day, and the next they're skeletons. I've scoured looking for flat worms, nudis, anything that could be doing this and there's nothing.
I have 25 assorted other corals that are thriving so I have NO idea what is happening.

These are my parameters - ph is a little low and Mag is a little high but neither are so off that they would be causing mass die-out of only one type of coral, are they?

Ammonia 0
Nitrite 0
Phos <0.1
Nitrate 10
Alkalinity 8
Ph 7.6 (we didn't have a skimmer until yesterday so hopefully that boosts it)
Mag 1360
Copper 0

Thanks for any advice

What kind of flow are they getting as to much or too little is harmful
What is your temp and calcium levels ?
Can you show pictures under whites ?
Are you using RODI water for your make up water and top off ?
How old is your tank ?

Calcium is in the post it's 0, it's a 32 gallon tank and we had a fluval 50 but recently upgraded to two jebao sw2 heads (recommended for our tank) and none of them seem to have had too much or little flow. Always using RODI water in the tank. It's 5 months old. Temp is 77 at night, lights raise it to 79/80 during the day.
I'm not sure what you would like pictures of? Thanks!

Calcium is zero? Do you have this confused with another parameter?

Do you have any photos of the afflicted corals? Best if they are taken under white lighting.

Oh my! I'm sorry, I was thinking copper. Calcium is 400ppm

How long's the tank been running?
I recently lost some hammers because I let my RO/DI filters go too long before changing them

Hard to get a good picture, but this is the state of the dragons soul currently

My tank has been running about 5 months. We buy our RO/DI water from the LFS.

What light do you have? Add settings as well

Fluval Marine&Reef 500mm settings are attached

Looks like it has been dying for a little while. The reason I say that is it’s flesh is very receded and looks like it has been for a bit. since there’s algae already grown over we’re it should be.

newreef_sb · Oct 13, 2023

It hasn't been though. It was fully out and beautiful yesterday morning. There's no algea on it, that's from the polyp dying.

Those lights are up pretty high. At 100% if I’m reading that right I’d turn down atleast the whites minimally or put them all at 50-70%

OctaviusBrine · Oct 13, 2023

They will still come out till they bail

Would that effect them all over the tank? They have been in all different location and all of our other corals are thriving. I wouldn't want to lower the lights and have them suffer? Our whites peak at 90% for 4 hours and are at 0-25% for the rest of the day.

The dark green were the flesh coat used to be it should be near white but if it’s green it’s slowly been receding. I circled it for comparison.

Maybe it's the angle but it's definitely not algea. It looked exactly like the one you posted yesterday. It had full bailout of that head and it was fully intact at the time. It definitely wasn't slowly dying.

OctaviusBrine · Oct 13, 2023

lowering the lights by 20-30 percent won’t kill them. You should always lower them when adding a new coral to acclimate them.

But it is that dark green is we’re the flesh used to be. I would assume when you first got it.
