I was thinking the same thing when watching them. A lot of the Dutch scapes have very little if any surface movement. I think that they probably have higher turnover than you think but the flow rate is less. I have what I would consider quite a bit of surface movement and the flow is pretty strong. I may try to split my return line to help reduce some flow but still move the same volume of water.
