Euphyllia problems

[Stahre]

Hello, I have had all my Eyuphyllia hammers for around 6 months.

They have been doing good until now.

I believe that my parameters are good.

Salt: 1.025
Ammonia: 0
Nitrite: 0
Nitrate: 14
Phosphate: 0.09
Alk: 9.1
Cal: 440
Mag: 1260

The ones marked in red in the picture is the one that has not been doing so well, the others seem to be good.

Possible ideas why this happened:

1. I installed new Nero pumps, and I think I ran them a bit high for 2-3 days. This is now fixed and the euphyllias have a smooth back and forth flow.

2. After last weeks water change, my alk spiked to 9.7. I’m now back to closer to 9

3. I have a six line wrasse, that I sometimes see nipping at the corals , but he’s probably only looking for pests. (I have inspected the corals, I certain they do not have any flatworms)

4. My salinity dropped from 1.025 to 1.024 last week as well.

No changes to lighting has been done in the last 5 months

Any input on why this might have happened is appreciated.

As seen in the picture, this morning, one head had ejected all polyps.

I noticed a obvious decline im my euphyllia when my alk spiked. My suspicion anyway!
