AQQA Multifunction Aquarium Air Pump,Powerful Rechargeable Battery Fish Tank Air Pump,Multi-Gear Continuous Mode+Intermittent Mode+Feeding Mode+Charge Pal,Ultra-Silent Oxygen Pump

So glad I upgraded my air pump for my 125, this is easy to use, simple to set up, a little bigger than what I was expecting but understandable for the power. I think it’s pretty quiet but if you don’t have water running it may be a little noisy but not bad at all.

Extremely happy with this pump.I’ve had quite a few different brands /types & this is by far the best one.Extremely quite & air flow,volume are excellent.Power goes out frequently in my area & I was using a small pump that would switch to battery in a power failure but it wasn’t very quite or powerful.This is the only pump I need now both for every day & power failure.Saving the small ones (a lithium & a battery one)for extended use in hurricane season.Seabastion approves as well.Also it’s aesthetically pleasing.

Nice and powerful battery backup is great for power outages. Unfortunately, the manual is not detailed on what each button does.

I'm still setting up the aquarium but I've had time to check out most of what the AQQA AQ-078 has to offer. 1st, more air power than I'll probably ever use. Photos 1 & 2 shows output at 3, photo 3 set at 8, both air stones at 18" below the surface. 2nd, at less than 35db (using their stats) I can not hear it, at all. (but I'm no spring chicken either). It's really really quiet. 3rd, I pulled the cord out to simulate a power outage and four or five days later the battery finally emptied. I had it on "continuous" the whole time. I'll check it again on intermittent. It charged 100% in about 5 or 6 hours. My tank is 125 gallons, 72" x 18" x 18", and if you have a location that can handle a 9" by 5" footprint no matter what size tank or tanks you have, I believe you will be as satisfied as I am with this purchase

Best air pump hands down saved lots of fish on power outages

This is the best air pump I’ve ever had it’s been on for almost a year non stop great product

I dont have all my aquariums connected yet but this pump is plenty powerful, but surprisingly quiet. Air flow and settings are easy to adjust. The touch screen is maybe a bit too sensitive and its easy to accidentally change your settings. Other than that I love the features especially the feeding setting. This is so much better and simpler than using multiple air pumps for multiple tanks.

The machine can be powered on, but no air coming out. It’s a big and heavy unit.
