Zoanthids and palys dying

[Nate_Krohn]

I’ve had 9 colonies and frags of zoanthids die and completely disappear over the past month or so. They completely disappear within an hour of them closing up. I need help!!

Sorry to hear of this. The community can help figure this out if you have enough info to share:

When did you cycle the tank?
Salinity
Alkalinity
Nitrates
Phosphates
What lighting do you have
Where did you source the rock?
Are there any corals that are doing fine and have been fine in there for a month or more?

Salinity: 1.025
Alk: 8.3
Nitrates: 10-15
Phosphates: .5-1
I use the dual current led orbit pros
The rock was dry rock from my lfs
The tank had been cycled for over a year and every other coral besides the zoas and palys are thriving. I’ve also had these zoas for over 4 months with no problems at all

Any recent changes? Also Cal & Mag params?

Calcium is 460 and Mag is around 1250

#s all look good, any recent water changes or maintenance on tank recently?

Last water change was Saturday and I do them weekly like I always have. I haven’t changed any of my maintenance since the tank started.

Anything near them that could be sending sweeper tentacles at night?

Seen any bugs (nudis) climbing in and around your zoas? I'm suspecting you might have zoa eating nudibraches. It's just a guess.

OMG, phosphate at .5-1.
That’s five times higher than what I run, ten times if your 1is correct.
Unless you mean 0.05-0.1, then that’s normal.
High phosphate is way bad for corals...

Yes I meant .05-.1 my bad

Try dosing some iodine, if you don't do so already.

I suggest dosing Fuel. I have a 45 gal aio & started dosing 2 ml twice a week a month ago when mine started shrinking & melting. Since then I have had polyps appear on plugs that I thought were long gone with no sign of life. Even my acans, which were previously doing fine, have really pumped up & developed more heads. I do a 10 gallon water change once a month & only run blues on my tank for 8 hours per day. My parameters are pretty much in line with yours except my alk is 7.8

Losing my torch and more palys now. Water is still fine. If anyone had any other ideas please let me know
