Euphyllia dying one by one

[Khoi_La]

Hi guys,
It has been a frustrated week starting with my gold torch melting without any reason. As of yesterday, my 2 year old frogspawn started to melt and loose 2 heads out of 5. The other 3 are looking as good as ever. But it doesnt stop there. This morning one of my 2 head gold hammer started to melt and im getting really confused and don't know what do to. I havent add anything new to the tank for months. The only thing ive done differently is adding vibrant 4 weeks ago for bubble algae. Is it the cause?
My tank parameter
Salinity: 35 ppt
Ca: 468
Alk: 9.12
Mg: 1484
Monitored by trident and test again with salifert and sera test kits
Ph: 8.14
No3: 20ppm

As for my big colony of wall hammer and other frogspawn and torches are doing fine. But im now afraid the others might act up as well

i was hearing so much good reviews about it so i gave it a try. I only use the recommended amount. big mistake. corals are dying and bubble algae are stil in tact

Check this thread. If all you changed is to start dosing Vibrant, IMO STOP. Do a large water change and wait.
