Yesterday there was a power failure and my aquarium temperature rose to
nearly 30 degrees C (90 F) The forecast is for a prolonged hot spell with
temperatures in the high 30s (degrees C) = 100 degrees F

The local pet shop owner reported that the fish jump out of her tanks if
it gets too hot.
Any suggestions on how to manage an aquarium during hot weather? (with or
without a power failure.)

get a battery powered aerator
If you use sponge air powered filters it can be a case of unplugging the
airpump from the tubing and plugging tubing into battery powered aerator.
Still warm water loses oxygen very quickly!!!!
If you still have power directing a pedastal fan onto the water surface is
the most efficent way other than getting a purpose made chiller unit.
Many people float frozen water bottles, and this can work for smaller tanks.

In a blackout bacteria in cannister filters will quickly suffocate and rot.
Consider giving them a clean in water drawn from the aquarium and leaving
the filter media in wet in open buckets until you get power and can re-pack
and start the cannister filter.
We face lots of blackouts around here and my tanks reguarly get up around
30deg C.
Putting some solar panels/batterys up soon, so going to have quite the
kickass backup.
