I have this problem. I tried scrubbing with a broom, but I need to
get a lot of water on and the algae were pretty adhesive. Is there
a way of loosening them without damaging the polythene? I am inclined
to try dilute bleach.

I did mine two months ago with jays fluid, just brush it on with a
yard brush, go have a cuppa, then power hose it off, not a trace of it
now :-)
