Use Barley Straw Throwers to keep your pond clear of algae the natural way. Barley straw is 100% natural and is the safe, effective & inexpensive way to improve water quality and stop algae growth without any risk to wildlife or plants. These Barley Straw Throwers also have added bacteria (the same as in the Clarity product) in biodegradable sachets, which helps reduce algae re-growth. Supplied in a TWIN Pack - each Barley Straw Thrower will treat a 3000 litre for 4 months.
Treating a pond with Barley Straw Throwers could not be easier - simply throw them into the pond! As the barley straw rots, it releases compounds which stop algae AND blanket weed growth. The throwers also have the same bacteria added as is in the Clarity product to help reduce algae re-growth by reducing nutrient levels. When the water is cold it takes approximately 4 weeks for the barley straw to start rotting and to start working, but the process happens much quickly in the summer - only 1-2 weeks when the water is above 20c. For best results add new throwers every 3 months, so that new barley straw is in place working BEFORE the straw in the original throwers has completely rotted i.e. remove the old nets once a new thrower has been in-situ for a few weeks. Supplied in a TWIN Pack - each Barley Straw Thrower will treat a 3000 litre for 4 months.
N.B. We also have 2kg Barley Straw Bales for LARGER ponds, which will treat a 6000 litre pond for 4 months.
