Swell Barley Straw Extract is a natural alternative to a chemical treatment and is totally harmless to all fish and wildlife.
Barley straw releases natural chemicals into your water which disrupt the production of algae. Microbes consume the nutrients that algae needs to thrive which stops any regrowth. This is an excellent product to use when the warmer weather arrives to keep your pond looking good and in great condition.
Dose 10ml per 450 litres (100 gallons) of pond water.
