If it for a pond just go to your local pet shop, buy som pete straw (which
should be pesticide free). Put the straw as muchas you can into a pair of
ladies tights.
Tie up the end and submerge in pond.

Works a treat! Last all season, and can be used for compost in the autumn.

Has anybody out there tried Flora APM ? It is a barley extract that is
said
to prevent algae. It is not an algaecide, and I believe it is supposed to
be
safe for plants and fish. I am thinking of trying it and would like to
hear
from anyone who has used it as to its effectiveness.
