This popping sound is very annoying so I asked the tech what could I do to resolve this concern.
So in a long discussion with the Hydor tech, he recommended either extending the cycling of the Smartwave Controller so there will be more quiet time between each annoying pop sound, not acceptable to me, or upgrade to the Wavemaker 2 / Wavemaker 4 with a Koralia 12VDC pump. The tech responded that all their DC circulation pumps do not have the popping issue because DC always runs in the correct direction.
Now let me add if you have a very loud tank or a tank in a loud area, you might not care about the popping sound, so you will enjoy the benefit of these pumps with the Smartwave Controller.
So, what if you didn't purchase or don't want to use the advanced features of a Smartwave Controller, well, let's just say all is actually very good. After the pumps are running, they are quiet with a small amount of low tone hum, barely audible, and therefore, I would say a good purchase for "non-controller based" usage.
I will add that Hydor support was very quick to pickup the phone and Hydor was very helpful and pleasant.
We have this in our 55gal tank to get a little extra circulation on one side of our tank and to give our live plants some flow and its awesome, its powerful enough to do exactly what we want, we almost went with a higher gph but the 600 we got is perfect!!!
