That is what I used to use for the 'problem'..no longer use as no longer
have a polytunnel.

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.
