Does anyone use JBJ Oceanstream Circulation pump on a wavemaker, do they make a clicking noise when they turn on and off?
 
I don't know if it's quite the size of a grapefruit, but it's a really big orange. I have a pair of them in a Red Sea Wavemaster Pro, one is absolutely silent, the other sometimes has a faint hum when running.
