Did I kill everything?

How long can corals live without flow? I turned off all the circulation to feed, and forgot to turn them back on for about 8 hours. There are NO FISH in the tank, just corals and snails... envision fish-less frag tank.

Probably OK...think of it as low tide

You should be fine. If coral can be shipped overnight in little plastic bags then your coral will live. I would keep the lights on the low setting to help them recover.
