Eheim compactON 600 Adjustable Water Pump

The EHEIM compactON 600 is a small submersible pump for moving water in freshwater or marine aquariums. Its adjustable output lets you tune circulation or a small supply line without immediately moving to a larger pump.

Suction-cup mounting helps position it in a submerged compartment. Leave space to access the inlet and impeller for cleaning, and match the outlet connection to the tubing used in your installation.

The compactON 600 must operate underwater; the external-use conversion available on certain larger compactON models does not apply to this size. Choose a pump for the flow needed at the actual lift and plumbing resistance, since a maximum-flow label does not describe delivery through every installation.
