The Nautilus DC return pump is an energy efficient and controllable solution for aquarium return pumps. They’re DC- powered and can be adjusted to run as low as 10%. There are 10 different output settings, so you can easily adjust the pump to suit your tanks needs. 3 built in feed timers enable you to choose 10, 30, or 50 minute feed times. The Nautilus control interface accepts a 0-10v analog DC control input, making it compatible with the Neptune Apex, Coralvue Hydros and other popular aquarium controllers. Nautilus pumps are available in 7 sizes, ranging from 300 gallons per hour for nano tanks, to 3,200 GPH for large systems. Each pump includes a variety of output nozzle sizes designed to work with vinyl tubing. They can also easily be hard plumbed with PVC. Designed for internal use only. The Nautilus DC Pump has a built-in slow start function and runs whisper-silent.
