The barley straw did work well in reducing string algae in my pond. Others
have said it didn't work for them. I think there are certain requirements to
make it effective. Such as: placing the straw near the top of the water near
or at the point where the water reenters the pond after being filtered. The
decaying straw also needs sunlight and oxygen to work effectively. I also
believe it may or may not work depending on other water parameters. There
are so many variables in different water environments that I'd be pretty
amazed if any solution worked for everyone. Barley straw is just one
possible solution that may work if conditions are right.
There are also other possible solutions like "managing nutrients to control
algae" that is explained in this article:
as well as here:
Keep in mind that any solution one tries can also be detrimental, so always
proceed carefully with anything you try unless you don't mind the
possibility that all your fish, plants, other creatures may be affected and
you may even have to start all over again from scratch.
