Hi I got 2 Goni Colonies 3 weeks ago, the first two weeks in the tank they were gorgeous and fully extending. In the last 4 days, they have been more shriveled up and semi-closed. I can't figure out why.

Tank: 75G with 20G sump
Flow: Medium
Par: 50-60 at bottom of the tank under AI primes
Feeding: Every 3 days Reef Chilli (not spot feeding)

Parameters 1 day before they went into the tank:
6/9/2021
Temp: 79.5
PH: 7.8
Ammonia: 0
Nitrate: 50
Salinity: 1.024
Alk: 8.3
Magnesium: 1000 (was low doesed it up b4 they went in)
Calcium: 440
Phosphates: 0.08
TDS: 0

Parameter Check A few days after colonies went in.

Magnesium: 1200
Calcium: 438
Phosphates: 0.1

Parameter Check Today
6/30/2021
Temp: 79.2
PH: 8.1
Ammonia: 0
Nitrate: 30
Salinity: 1.025
Alk: 8.2 (dosing over the next 25-48 hrs to get it back up towards 9)
Magnesium: 1300
Calcium: 440
Phosphates: 0.1
TDS: 0

So Far:
I have tried to spot feed them.
Move them into different areas.
Did a 15% water change 2 days ago.
Re-tested all parameters.

The green colony seems to be having the most issues. The darker gray/blue colony is looking a little healthier and that small Goni frag behind the colony is doing excellent. Any advice?

P.S. There are no other corals in close enough proximity to be affecting them.

The great state of Texas
Hello,

What are your phosphates at? I have multiple goni's and have always found they do not care for high phosphates or even nitrates on the high side. Target 100-150 PAR

Where’s phosphate?
If that’s not in the range, corals will become unhappy.
