This may be interesting to those who have algae in their ponds and
struggle to contain it. I've only just heard of it and it's nothing to
do with us! Unfortunately, it doesn't look as if it controls duckweed!

I think they use Dyofix Pond Black or something similar in Cow Pond in
the Great Park Windsor, it's a large lily pond (lake) and the black
water really sets off the waterlilies which cover it.

The person I saw writing about it has a reflective pool and uses it for
that. The range is interesting.
