Written by Jordan

For most fish keeping hobbyists or enthusiasts, a tank crash would be devastating. Losing most or all of your tank life in a short period of time is difficult to recover from, and may force you to restart your whole load. Tank crashes aren’t common. However, power outages can cause tank crashes if you’re not prepared to handle them. Getting the best aquarium battery backup system hooked up to your tank can insulate you against the risk of losing your fish and plant load from power failures.

You have a number of options for battery backup systems. Uninterrupted Power Supply (UPS) systems are a common choice that’s widely available, because of its application for a wide variety of electrical equipment. Some tank owners choose to use generators because of their ability to last for as long as necessary, although they’re less popular than UPS systems.

Whatever you choose to hook up to your tank, it’s advisable to set it up sooner rather than later. You never know when a power outage might occur. If you know there’s a storm coming in or any other event that may threaten the power supply, get a backup system now before you’re stuck without it when you really need it!

Why Get a Battery Backup for Your Aquarium?

What make an aquarium battery backup a good idea? Each fish keeper may be different, but there are a few convincing reasons that apply to most people:

Maintain life support systems

Essentials like filters, powerheads (pumps), air suppliers, and, heaters can all be connected to a battery backup and operated for anywhere from a few minutes to hours at a time. Maintaining life support systems is crucial in delicate aquarium environments. Many fish keepers hook only the bare necessities up to their battery backups, in order to help them last longer while the power is out.

If the power outage lasts a little longer, you can run tank essentials on short intervals over a longer period of time. Some UPS battery backup systems can do this automatically, though most will require you to switch them on and off manually. This is only recommended if there is an extended power outage, as it would be difficult to maintain on a regular basis.

Reduce aquarium casualties

In aquarium environments that are more particular, such as coral reef aquariums, or in locations that have vastly different temperatures between the room and the water, a backup is useful for reducing casualties. If the power were to go out for a few hours, tanks in either of these situations could suffer a lot of casualties. In reef tanks, coral casualties could be dire and may cause the entire tank to crash.

Temperature is the most dangerous variable during a power outage. If your tank is in a very hot or very cold location, or if the room temperature is nowhere close to the water temperature, power outages can be a death sentence in your tank. If the tank water temperature is close to the room temperature, a power outage is unlikely to affect the temperature enough to matter.

Peace of mind while away

While you’re near your aquarium, you can solve any problems that come up. However, if you have to leave for an extended period of time, a battery backup will give you a sense of peace while you’re gone. Whether you’re going on vacation or just leaving the house empty for longer periods of time, you won’t have to worry as much about the tank crashing while you’re gone.

Protect your investments

Aquariums and the life inside them are very expensive. Although the tank itself will not fail, everything within it can die if the power stays off for too long. Depending on what’s inside your tank, your load could represent a significant investment. A battery backup helps you protect the time and money you’ve invested into developing your tank.
