Questions & Answers

6 Customer Questions

How long do they operate on 2 D Cells, and how many gallons do they aireate?
Answer by ChewyAug 29, 2017
The pump has been tested and worked by other customers, it lasted 3-6 hours using 5 gallon buckets holding the fish.

Does this come with hoses to insert in aquariums?
Answer by ChewyNov 19, 2017
This product includes 18 inch tubing.

Would this suffice for a long distance move?
Answer by ChewyMar 26, 2021
While this is intended for power outages it may also be used for transporting.

Is it waterproof?
Answer by ChewyJun 25, 2019

Live where there are constant outages?

In the summer where I live, storms constantly knock out the power. I have 4 aquariums of axolotls that depend on the air pumps so these are great to have around. Just make sure you keep batteries stocked. They're simple to use. Just detach the tubing from your air pump and attach to nipple on these. My only complaint would be that there is only one nipple so that means only one filter. Some of my larger tanks have 2-3 sponge filters. But seeing as it's only temporary, it's fine.

Great LIFE SAVER for fish in a power outage! Rest assure fish will have air with this battery air pump! But I would advise a (check valve) on tubing, before using.

missing parts

The box clearly states it comes with tubing and an air stone. And it does not. For as low power as it is for 17$ you’d think it would include everything it says it would. Do not recommend. I’ll now have to go out and replace this.

Great product. It’s quieter than the other brands that I have.

What's wrong

I just bought 2 new air pumps and have used them once for an outage. I was transferring a fish to a friend and it didn't work, nor the other one. Put new coppertop batteries in and no luck. Is there something I can check on it. I love these and have used my old ones for years. Can't understand why neither one will work.

Beware defective

This pump is terrible, cheaply made. It stopped working completely after 2 months. Don't waste your money

Impressed indeed.

I must say, these made the anxiety over an upcoming 15 hr drive drop a lot. I was worried about keeping my fish in a 20 gallon container with just holes in the top. I just tested these out. They put out a lot of bubbles. The motion will mimic the current from their tank's pump. I just hate having them in the dark for so long. If it's for half a day I guess they'll be okay.

Must have for power outages

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!

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.

Life saver

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.
