The AI Axis 20 is a compact and intelligent centrifugal DC return pump designed to bring premium features to smaller aquarium systems. It provides quiet, reliable water circulation from your sump or rear filtration chamber to the main display, with full wireless control through your smart device. This pump integrates seamlessly into the AquaIllumination ecosystem, allowing for sophisticated programming and coordination with other AI equipment for a fully automated reef experience.
The Axis 20 delivers a maximum flow rate of approximately 185 gallons per hour with a max head height of 5 feet, all while consuming a mere 12 watts of power. Key features include full controllability via the MyAI or Mobius app, allowing you to create custom schedules, engage a temporary feed mode, or calibrate the pump's output to your specific tank's needs. A unique calibration feature also prevents back-siphoning by keeping the pump running at a neutral flow, which eliminates air bubbles upon restart.
This pump is the ideal solution for owners of all-in-one (AIO) nano aquariums up to 15 gallons. Its small footprint, measuring just 2.125 inches in diameter, allows it to fit into tight sump compartments common in nano tanks. Reefers who desire the advanced control, quiet operation, and smart features typically found only on larger, more expensive pumps will find the Axis 20 to be a perfect fit, offering high-end performance in a compact and affordable package.
