What’s your rockscape look like?

its a simple middle setup about 6 inches from the surface could put a fist mostly all the way around between rock and glass

You could put it in the back above the rockscape if you don’t mind seeing it there. Or try it high on either side. I’d move it around until you get good flow without blowing sand everywhere. Putting it on the opposite side of the return flow might be helpful.
