Are these coral dead?

[BabyShark]

I got these coral from my lfs as they were recommended from the employee to be beginner corals. They don’t appear to be doing so well. My salinity was at 1.030 before, but I since changed it to 1.026 after testing. All softies are flourishing though. Do any of these have a chance?

What are your other parameters?
What is your lighting like?
How long has your tank been up?
How were the corals when you first got them?
Did you dip?

I'll be honest, they look dead. One still has some life. The key to reading is stability! Sorry don't give up!

The third coral still has a chance, not sure about others

SALINITY: 1.026

AMMONIA: 0ppm
NITRATE: 0ppm
NITRITE: 0ppm

When I got some of the corals they did have bubbles on them, but the employee said it was fine. This was about a month ago and these specific corals did okay for a few weeks until now.
My tank has been running for about 8 months and I just recently put corals in them!
I will test my phosphate tonight after I pick up the testing gear from the store!

Phosphates?? Also having zero nitrates could be the issue. NO food or nutrients in water for corals....

What should the nitrate be at?
