Battery Backup for Aquariums

Battery backups are good insurance for power outages, but how should you choose one for your aquarium?

Every week, when you perform your aquarium housecleaning, scraping algae, changing water and other tasks, add one more job. Turn off all power (electricity) to your aquarium. Wait two minutes. Turn on all power. Did everything restart by itself? If everything in your aquarium smoothly returned to its normal status, excellent. If some items, including filters, powerheads or lights, did not turn on or resume their duties without you shaking them, hitting them with a blunt object or swearing at them, then you have a problem.

Some time ago, while I was gone overnight, the electricity went out for about 20 minutes. When the power was restored, the powerheads did not turn on, so there was no water motion, no filtration and no oxygen exchange at the surface. Some fish died even though the power was off only briefly.
