I'm not sure I did this idea justice. I feel the strip of algae on the water surface is too narrow, however I could not enlarge it (in camera, at least). I would have had to get higher, which wasn't possible without a ladder, or perhaps a drone. Raising the camera lens would have included the actual reeds along the shore, which wasn't in the plan.
I get the feeling of descending into the depths into an alternate upside-down world.
