This battery powered air pump is a must for every jellyfish owner as it provides auxiliary air when main air source fails. Since the Jelly Cylinder aquarium are powered by air the backup battery pump is a lifesaver in cases of power outages!
(Temporarily connects directly to the main tank line in place of the main pump to provide flow during a power-outage)
- It is a reliable back-up air source during household electrical power failures.
- No tubing or air-stone required for Jellyfish aquariums.
- Uses two "D" cell batteries (not included).
