Weird looking zoas

t1a1c1h · 02/12/2016, 04:07 PM

We recently added a small zoa colony to our 90g reeffect tank. After a couple of weeks they were looking a bit out of sorts so we dipped them in generic coral dip from the lfs removing a load of amphipods with a blaster. That was two weeks ago, they haven't opened up since and now look pinched at the tips (see pic), any advice w what to do? Are they dead/dying? Tank params stable: pH 8.0, nitrates 5 phos 0.03 Alk 10.5 calc 450 salinity 1.025.

How much flow are they getting? And how much light?

Lighting wise we have them under ai prime leds and a slow to moderate flow. They were fully open with the same lighting/ flow settings till dipped a fortnight ago.
