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.)

When I had my aquarium maintenance business in LA; heat waves, rolling
blackouts, & air conditioner failures were common. We had 2 liter
frozen pop bottles stored in the freezers at our customers to place in
the tanks at this time, we also covered the tanks in wet towels where
the evaporation from the wet towels kept the tanks cool. We were able
to keep tanks reasonably cool (under 27 C) when outside temperatures
were over 35 C even with large aquariums.

It is interesting to think about heat problems when our kids just had
their 3rd snow day in a week!
