Eheim · Circulation / wavemaker
Eheim streamON+
streamON+ is a compact propeller pump on a magnetic mount, used to push water around the tank rather than through a filter. It swivels on a ball joint and has a slider to throttle the outflow, and it is very frugal with power.

Will it suit my tank?

Best for
High-tech planted tanks that need extra circulation to push CO2 and nutrients into dense stem groups.
Worth knowing
Even the smallest moves a lot of water, so on a nano or with delicate fish, start on the lowest setting and aim it at the glass.
What stands out
- Magnet mount, easy to move and angle
- Ball joint for full 3D positioning
- Slider to reduce outflow
- Only 2.5 to 12 W
