Unhappy corals

[littlestar]

So the lovely corals that came with the tank I saved from closure don’t look happy to me :(

There is pulsing xenia, that hasn’t looked happy since I’ve had it. Then GSP and and BTA

Please tell me what I can do to make them thrive, and what is best to feed them, as I have seen a few different ones and don’t want to buy the wrong thing!

Thank you in advance

We would need a lot more info from you... what are the water parameters? What type of test kit do you have? What type of light is on the tank? What do you have for water movement in the tank? Just those 2 small pictures show me this is not a not a correctly built saltwater tank.

I have taken on this tank from someone who was moving overseas to save it from being shut down. I used the API master saltwater test kit and parameters are-


Alk: 9.8
PH: 7.8
Phosphate: .8 PPM
Calcium: 419
Mag: 1097
Ammonia: 0
Nitrite: .1
Nitrate: 32ppm
Salinity: 1.025

I am planning on adding aragonite sand to the bottom and more rock. I have a strong white and blue led light over the tank, but happy to buy an additional light/upgraded light if needed m.

Small surface agitation, no power head or wave maker- again, will get if needed.

Just want to do everything I can

What about the PAR of your light?
Any recent changes to your tank?

No Idea on PAR… light is 6500k led. Daylight and blue light

No recent changes

Hi

I would do a 50% WC because your pH and Mg are both low. I like pH 8.2 and Mg at 1 300 at least but 1 400 is my favorite.
Corals look fine they just need to adapt.
More water movement wouldn't kill them since you need more aireation and make sure there is no debris on them and other benefits the water movement has.
BTA looks amazing it even has its bubble tips so relax just feed her some shrimp once a week. The other 2 soft corals rarely benefit from feeding they just need moderate light and current.
