Zoanthid help needed

[Baffels]

Hey folks. Recently moved into an apartment and downgraded from ~500g to a 45g AIO. Tank has been up and running for 6 months using rock and filter media from my old 5 year old tank. My zoas were doing great for around a month and are now closed up and appear to be dying. I also just did an API test, results are below.

My thoughts:

Nitrate/phos to high? I have maintained higher then this in the past and had zoas flourishing though...
Could the ALK be to high for Zoas? I usually maintain ~12 using the redsea coral pro salt.
Lighting? I have put them in 75 par, up to 150. They are currently in 100. They sometimes look like they are reaching, but have more then enough par.

As a note, other corals in the system are doing... ok. Not great, but ok.

Flow is moderate with a reefwave 25.

Equipment:

JBJ 45 AIO
Dosing Redsea 4 part
XR15 set on AB+ for lighting

The brown ones look like they are stretching. I really don't see anything in your parameters, and to me corals doing ok not great when parameters are fine often comes down to lighting.

I'm thinking lighting as well. Not sure what to do, everything seems ok PAR wise. I could swap in my old AI prime and see if that changes anything...

Trying my AI primes, but don't expect much of a change... any other thoughts?
