MightyJet AIO (All-In-One) Return Pump
The MightyJet AIO (All-In-One) DC Return Pump is an excellent choice for nano aquariums ranging from 10 to 25 gallons. The MightyJet is super quiet, has a run-dry protection, two different flow modes with 9 different speeds, and a feed mode.
The MightyJet pushes up to 326 gallons per hour, but can be dialed to your preferred flow rate with the equipped controller at the touch of a button. Once you find the setting that is right for you, you can lock it in by holding the down-arrow button, that the controller will display "LC" when set.
