Works with your controller
A 0-10V analog DC input makes it compatible with the Neptune Apex, CoralVue Hydros, and other popular aquarium controllers.
Slow start, whisper quiet
A built in slow start eases the pump up to speed, and it runs whisper silent once it's there.
Tubing or hard plumbed
Hose barbs for vinyl tubing are included, or hard plumb with PVC using the threaded inlet and outlet.
Performance
Flow at your head height
Flow drops as head height rises. Measure from the pump up to your return outlet, then read the chart to see what each size delivers at that height.
Between sizes? Go up. Every Nautilus turns down to 10%, so a larger pump can always be dialed back.
