The 2 most important
factors are oxygen depletion & heat loss.
Oxygen:
This is MOST important because your fish breathe &
everything in your tank needs oxygen. Over
time the livestock exhaust the oxygen supply.
Those running an AquaCorals DSB/LR/Sump system will
have more available oxygen for much longer than a
mechanically filtered system. If you don't
have a generator, battery operated air pumps are key
to survival. They are inexpensive, especially when compared to potential livestock
deaths! Everyone should have one (or more) on
hand along with airline tubing and air stones.
Heat loss:
As your tank temp cools microscopic animals will
start to perish. Fish can handle cooler water.
Their metabolism actually slows down helping to
further preserve the oxygen in the system. We
don't want to let it drop more than 2 degrees before
intervening though! Heat water any way you can & fill 2 liter soda
bottles (or any clean plastic or glass
container you can put a cover on & seal. Sink
the bottle(s) in your tank. Repeat when the
bottle(s) cool. Always, always, ALWAYS keep a
glass thermometer in your tank. It's the only
way you're going to know what your temperature is
during a power outage!
