Review on 🐠 Efficient Silent Air B10 Battery Operated Aquarium and Fishing Air Pump - Aerates Up to 29 Gallons by Lindsey Teel

Bought two at the same time and both different. It looks like one is an older model and the other is a newer one. Both work and really put me at ease in the event of a power outage. Last winter we were without electricity for 8 hours. Not as long as some parts of the country, but long enough for me. Now my fish have a chance to survive with portable air. Really calming.
