Fantastic offer on natural water-clear treatment that lasts for a whole six months for less than £12. Place barley straw bales in your pond and as it breaks down and decomposes it produces a by-product which feeds on the nitrates that green algae relies on. The algae starves and your water becomes clear again.

• Safe for the family and pets
• Totally organic
• No-mess
• No measuring

Your medium bale of barley straw is contained in a net so the straw is kept together for less mess.

2x medium bales are perfect for a pond of 2000 gallons/9000 litres (13x13x2ft) for 6 months- perfect for over the spring and summer or summer and autumn.
