I do think water movement is important even in a plant only tank for at least two reasons:
- Water circulation allows for circulation of nutrients in the water column. Some plants absorb more nutrients from the water column than from the soil.
- Poor water circulation is often a contributor to algae and BGA. It's not the only contributor and isn't always the key contributor, but it is one nonetheless.
