FAQs

How long can my fish tank go without power?

Your fish tank can go without power for 3-12 hours. It depends on various factors like the size of the tank, number of fish, etc. If you have a lot of fish for your aquarium’s size, your fish will survive for a period of 3 to 9 hours when the power is off. In an understocked tank, they will breathe for up to a day or two.

How long will a battery air pump last?

Battery air pumps can last from 12 hours to 72 hours of continuous usage, depending on the model. Look at the product description and the battery’s rating in milliampere-hour (buy higher mAh batteries for greater longevity).

Do I need an air pump if I have a filter?

If you have an air-driven filter (sponge or corner filters), an air pump is necessary to power the filter. If you use a power or canister filter, using an air pump is optional. A strong-enough filter helps circulate the water as well as aerate it. Although it is not compulsory to have an air pump if you have a filter, air pumps aid filters with better water aeration, thus better biological filtration.

How do I protect my aquarium from a power outage?

The most foolproof solution to protect your aquarium from a power outage is a battery aquarium air pump. It will keep your fish alive and healthy by delivering a constant supply of oxygen. Depending on the model, air pumps can maintain a sustainable environment for 12-72 hours, which is ideal for getting your fish through those worrying power outages. You also shouldn’t forget to keep your fish warm. Using a battery backup #ad is the best option as a fish tank heater will consume a lot of energy.
