In CAse of Light Crisis

[411cottam]

Just curious if say your lighting system goes out totally. How long will the corals, anenomes, and clams survive with no light. I knew when I ordered my metal halide system it took about 4-5 days to get in. ANyone experience this or know the safe zone with no lighting. also, what about heat? I run with a back-up heater. What low temp. does your system get stressed?

I have metal halides that I leave off for 7-8 days at a time when we go on vacation, I just leave the PC's on. They should be fine for a week, in the wild, there are times when the sun is covered by clouds for that long.
