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.
