hi,
SNIP

i've heard of this sulfur/sulfide toxin.. does anyone know how long will
it
be ok before things start going anaerobic? (I'm thinking about several
hours
worth of power failure.. not shutting it off on purpose) or is this one of
those YMMV thing...?

I'm out of my league here, but I suspect that it would take more than a
couple of hours, but a heavy organic load could go anaerobic pretty fast.
The question is how long it would take to produce enough H2S to cause
problems. That I don't know.
