Zoathids dying!

[eqbal9947]

Hey everyone.
I’ve been having a problem with zoas slowly dying.
They normally do Wel in my tank but some of them have been dying
At first their skirts swell up and then they melt slowly
I have a bad pic of one with a swelling skirt on a spellbinder zoa.
Parameters are good
Nitrate 35
Phos .10
Mag 1400
Cal 440
Alk 8.8

Have you checked for Zoa pests? Have you noticed any fish picking going on?

Nitrate is somewhat on the high side imho.

I’ve looked at previous ones and haven’t noticed anything.
I’ll look at these spellbinders alittle closer

it’s alittle high but really okay for zoas. I’ve had nitrate at like 100 with zoas and they were fine
