Crashed tank

[jimmyisfishing1101]

I was on a road trip for 2 weeks and just arrived home and I came home to 7 dead corals and bubble algae all over the tank. HELP!

I removed all the dead coral before the photo

Need more information about your tank

Parameters?
Equipment failure?
Anything you have added recently?
Were lights and everything working properly on your tank when you left and when you got home?
CUC?

I would do water change, test your parameters and start again. Try to figure out what went wrong
