Review on 🐠 Penn Plax PEN-019 Air Pod Aquarium Air Pump - Power Outage Auto On, Ensures Fish Safety, 55 Gallon Capacity by Natalie Noleal

Many days off! I have this Air Stone Bars food in 2 aquariums. The automatic switchover to battery operation works and the performance remains high. Although I haven't checked the actual battery life. But I have a pack of D batteries. For around $30, this is great peace of mind. We're in Florida, so we always prepare for the X word. So during the storm if the power goes out before we can start the generator or we have an evacuation I'll add batteries and cross my fingers. A little noisy. I have a whisper pump, but it's more powerful. I put it on a rubber mat and it helps.
