Tank issues

[Pacman]

Hi guys

I've started a new tank n was running all fine for 2 months. I've LPS a little SPS with fishes. And all these are fine in the tank for abt a month when I realized my turbo snails started to drop. They didn't die but seems like couldn't claw n the wall. Then a few days later all the corals suddenly closed. And the ordea

The ordeal begins. All the sps dead follows by the seacakes n starfishes. I took all the LFS out immediately. But all the fishes are fine. Please advise what could happen. Thanks

Already cycled for 3 weeks and added corals and fishes for few weeks and everything was doing fine. When snail dropped, I checked my kh, mg and all appear ok.

I dosed bacteria once to twice a week after finishing the cycle. And started the Giotech A B C and D plus calcium for the clams. Water change every 5 days.

I doubt it's copper as my shrimps are ok. I heard if there is copper the ahrimps will die. Any advise what would cause the snails to drop and die? Thanks.

Excessive nitrates or lack of acclimatisation. Salinity is either too low or too high.
