I tried a nano Koralia 900 in my densely planted 65 liters some months ago and the flow was high but not that much... and it was fixed at the black glass, so there were only 30 cm of water in front of the pump. I also noticed that the flow was not so directional as you would expect looking at the design of the pump. As a result, the flow around the tank was significant, plants were moving but I had no problems with substrate or debris floating all over the tank. So a single nano pump IMO won't do very much in 240 liters. The advantage is that this model is quite small and silent. Maybe having two of them instead of a big and ugly one could work.
In my case I finally decided to simplify the hardscape to improve flow... Much easier, less energy consumption, less equipment on the tank.
