Suddenly Euphyllia is rapidly dying

[loops123]

Hi all,

I have quite a range of euphyllia in my tank that's been doing well for months.

Suddenly the are starting to die one by one. It usually starts with one head that becomes completely deflated after 24-48 hours it's gone.

My parameters are very stable at:
KH 7.8
PO4 0.05
NO3 13
Mg 1360
Ca 450

No light or flow changes in months.

Shops are currently closed, but I do have peroxide and someone else suggested dettol. Do you think it's worth a shot?

I'm clueless what to do... Bit I'm pretty sure if I don't act they will be gone tomorrow.

Below one of the heads looking like this, I'm not really seeing brown/jelly though.

Thanks!

You've had them all for months only? How many months? What is your lighting? How are other corals, why only euphyllia affected? Can you show a full tank picture?

Personally I see no benefit to a dip after a coral has already been in the tank for months..........

#reefsquad may be able to help. I think @Rocks reef is knowledgeable with these corals, if he has a minute to take a look.

Good luck!

Your parameters look fine, I would focus on par and flow, both should be moderate. I’m curious to see where these are placed in your tank, waiting on a picture. Remember, corals can be in decline for weeks or months before it can be seen in their outward appearance.
