Don't forget that a reef is really just a pretty looking battleground. There may be something attacking the softies who are then fighting back with chemical warfare which is ****ing off the other corals. It's vicious circle. Just work your way through the solutions: water change and parameters, carbon (lots), look for pests like Xenia-eating nudibranchs, crabs, etc., make sure nothing is touching/ relocate certain corals, pray.
