Come on over and then you won't be able to say that.

And on a side note I was curious as to why some people's GF died
(at least that is what some posts claimed) during
the east coast blackout. Why would they die so fast if the filter
stopped for 24 hours? How would that differ than from someone just
not cleaning the tank, you just would not have dirty water circulated
that's all.

If you've got a canister filter that doesn't have any circulation for a
while, it goes anaerobic and can spit out poisonous stuff when the
power comes back on.

Also if you're overstocked and are relying on your airstones, no
airstone = no O2 = dead fish.
