Yea. Coraline loves to grow on plastic and pvc.i was also thinking of spraying my elbows on the return manifold black but I was hesitant to put them in the water painted. I figured in time they will be covered in coraline algae.

nicely said David. lolNo moving parts. There is a Venturi, that draws in additional water volume. vanes inside upset the flow & create a turbulent effect. Someone makes one that is mechanical as well. The water flow causes the nozzle to rotate. I can’t see it working any better than this though, and I’m sure it would be somewhat of a hassle to keep the mechanism clean.
