Looking better!
I've noticed in a few pictures that in the lower right area where the 45 degree (well, technically 135 degree) corners are, on the floor of the pool some pictures are uniform bottom color, others look like a discolored blob in that area. Are you getting build up of dead algae there and then when you sweep it churns up and gets filtered or is there staining?
Have you fired up the vacuum yet? I know my robot helped get the sediment/dead stuff off the bottom quite a bit, improving water clarity.
