Description
Product Overview
Power outages are one of the greatest risks to aquarium livestock. Even a few hours without adequate water movement and oxygen exchange can place fish, shrimp, corals, and beneficial bacteria under significant stress. The JBJ U.S.A. MAXUM Air Pump with Battery Backup is designed to provide peace of mind by automatically supplying life-sustaining aeration whenever electrical power is interrupted.
Whether you’re maintaining a freshwater community aquarium, planted aquarium, shrimp breeding system, marine reef aquarium, bait bucket, or quarantine tank, the MAXUM Air Pump helps keep oxygen levels circulating when your primary filtration system is offline. During normal operation, the unit runs from household power while keeping its backup battery ready. If a power outage occurs, the pump automatically switches to battery operation, helping maintain critical oxygen exchange until power is restored.
Compact, dependable, and easy to install, the JBJ U.S.A. MAXUM Air Pump is an excellent addition to any aquarium emergency preparedness plan. For hobbyists who have invested countless hours caring for their aquatic animals, battery backup aeration provides an extra layer of protection when it matters most.
