Algae is probably the pond owners biggest problem and people try everything to get rid of it, even barley straw. This is becoming a common method and companies are even selling bags of it for small back yard ponds, but does it actually work?
If you think about it for a minute, it does not make any sense. Why would barley straw work? Why not some other kind of straw?
Even if it does work, it seems a shame to use it in a pond rather than make beer out of it!
