Swell UK Barley Straw Mini Bale Pond Treatment Twin Pack

Barley Straw is the perfect way of controlling blanketweed and ensuring crystal clear pond water. Not only is it effective, but it's also completely natural. Our bales are the perfect size for a variety of ponds. Each twin pack of barley straw bales come complete with net bags for easy handling and should protect your pond against algae growth for up to 6 months per bale. It's easy to use as well, barley straw extract naturally disrupts the development of each algae bloom and will destabilise blanket weed, so it can be removed through your pond filter.

Barley straw works by breaking down in pond water, producing a variety of chemicals that prevents the growth of algae. While these chemicals don't kill algae they send signals to the algae that tell it to stop growing, this is why barley staw is often called 'algae control' and not 'algae treatment' or 'algaecide'. This means that you shouldn't buy barley straw if your pond is already covered in algae, instead you should buy it as a preventative. If your pond already has an algae problem you should use chemical treatments to control it.

Please note: Swell Pond Barley Straw Bale comes as two barley straw bales packaged together.
