Please advice on a small wave pump

Hi ,
I have a profilux 4 WITH MY aQUARIUM and i would like to have a small wave pump ( magnetic? ) at the bottom.
Is their any small unit that is supported out of the box by GHL like a : Eheim Stream ON stromingspomp

Will this work or can you recommend something else ?

Any 1-10V compatible pump can be used alongside the P4 controller. Take a look at the Tunze NanoStream 6040 pump which is controllable via the P4. You can use this an a GHL Tunze 1 cable to control the pump.
