yes they are and it is eerie. having been to many tropical coastal cities I can tell you the wave action calms down at night (unless it is storming) and the water becomes calm. I have even noticed this while I am sailing in the middle of nowhere. now this is just surface action, the tides are still moving and the currents don't slow down so do we in our tanks need a photo cell to calm it down at night. Not in my opinion as I am not trying to recreate the wave area on the beach.
