The reliable Marina Battery-Operated Air Pump for Aquariums provides a backup air source during power outages. When your aquarium’s main air source fails, you’ll still be able to operate aquarium accessories like air stones, air curtains, air-driven protein skimmers and air-actuated ornaments. It also keeps the water circulating for a healthier aquarium. The Marina Battery-Operated Air Pump comes with 18” tubing and an air stone and requires two D cell batteries.
Provides backup air source, perfect for when power outages occur
Includes air stone and 18” tubing
Portable aerator unit is great for transporting fish
Circulates water to release carbon dioxide throughout the aquarium
Requires 2 D batteries (not included) for operation
These are a lifesaver! I keep 2 sponge filters in my 180 gal along with a canister filter so when the power goes out I hook the sponge filters up directly to these. Wrap my tank in spare blankets and we've survived many outages up to a few days with this setup (I boiled water periodically on my propane range for them when power was out multiple days). They're cheap enough to keep a spare, my first one died after 3 years of use (but we lose power a dozen times a year where I live).

Works great when your power is out! It does come with a short tube and air stone that are inside the pump. Take the screw out and open it with the clasps. It is noisy but we can live with it for a while.

I have several of these Marina battery operated air pumps and they have saved my fish several times. Every winter we seem to have a power outage that lasts for a period of a day up to a week. I have one for each of my big tanks but two or three small tanks can be serviced with one pump. I've never timed the battery life but they last for most of the day. However, the pump has no insulation or sound deadening so it is very noisy. Very. But in an emergency, a noisy pump is better than dead fish.

I highly doubted this would work well. I have a 125 Gallon Fishtank and my power went out for 4 days and i used this pump to keep the tank up to par the best i could and it more than exceeded my expectations so i bought an extra one. 2 of these now with large air stones works great in a large tank. Does take 2 large D batteries not sure how long they last but like i said 4 days no power at home and these ran non stop no issue and never ran out of battery power. I highly suggest this product for a back up power supply.
No tube and bubble stone

These Marina battery powered air pumps are great for both power outages and for traveling. I now own 4 on them and trust all 22 of my tanks with them during emergencies.

Saved my tank

I moved to a mountain community and sure enough, the electricity went out. This battery operated air pump saved my fish tank. The electricity was off for almost 4 hours. The pump performed like a dream.
A must have for anyone with an aquarium

With an airstone or sponge filter, this will keep your tank aerated during a power outage. It works great for what it is meant to do!
Haven't Tried Yet

I bought this in case of power outage and watched a You Tube video recommending it. I expect it to work just fine but should probably try it BEFORE I need it.
