Most aquarium inhabitants need changing (fluctuating) water currents, such as in rivers or coral reefs, depending on their origin. With the right circulation and/or flow pumps you can achieve constant movement, but how do you generate a varied flow?
Eheim Streamcontrol offers the ideal solution. Plug the pump's plugs into the supplied double plug socket, switch on the device and set the flow intervals. Two programs are available: a) alternating pump frequency and b) synchronous pump frequency. You simply determine the time intervals with two buttons.
Before feeding, use the pause button to interrupt the power and the pumps will be turned off for 10 minutes. After entering, the set program continues automatically or simply press the button again.
