Please tell me the source of your optimism, as research does not know exactly what triggers this phenomenon, which has only been occurring for 10 years, nor does it know effective treatment options, and the reefs will take decades if not centuries to regenerate and probably no one writing here will live to see it.
And to all those who found the reefs in an acceptable condition a few months ago: SCTLD kills corals from 60% to 100% in just a few weeks to months. There is no need to get lost in pessimism here or cry about a ruined dive trip, but to call things as they are.
