Top Fin Battery Operated Aquarium Air Pump
Good idea, needs work
This pump is LOUD.
The fact that it's battery operated is a plus and makes it good to have on hand in emergencies, or if you need to transport your fish.
I bought it with the latter in mind, and was going to use it on a regular basis as well, but the motor's hum is just too strong. I can hear it from two rooms away!
A good emergency purchase, but wouldn't recommend regular use.
