I have a 1500L/hr power head which just blows forward.
I have it blowing (from a distance) against some of my corals and they appear to be doing much better since they have had this extra water flow.
I would like to, however, modify this so that it sways back and forth from side to side. The objective is to more accurately simulate the flow of a wave current.
Does anyone know how I might do this, or if there are any attachments I can add to this to achieve my objective?
The power head is very similar to this design:
Thanks in advance.
