I finally got a response from the school today. I don't know why it took them two weeks but I guess mentioning palytoxins got their attention. They saw a lot of dead inverts and no live fish (no dead fish either, but I'm not optimistic). The Dean of students couldn't tell if the corals were alive or dead but I'd assume dead.
Does anyone have tips for cleaning up and starting over?
This really sucks.
Really sorry, I would just do 100% water change, maybe replace the sand bed and let things stabilize. Remove the dead obviously and clean up the algae manually.
