Product Description

Extract of Barley Straw is an environmentally friendly product to gently balance pond water chemistry aiding water clarity and encouraging the take up of nutrients by healthy plants. The formula is based on specialist straw technology, which is proven to gently improve water clarity without harming the fish, wildlife or plants within the pond.

Extract of Barley Straw is formulated from organically grown British Straw, under the F.A.A.B (Farm Assured Scheme). No herbicides or pesticides are introduced during the growing process, or during the production process.

  • Natural products sometimes work less quickly than available chemical products but offer a safer solution
  • UV can affect the activity of the product. It is important to dose more regularly (twice a week) if the system utilises UV.


Direction of use

Directions of Use

Dosage: 125 mls per 1000 gallons initial dose

20 – 40 mls weekly thereafter

We recommend dosing 125 mls per 1000 gallons as an initial dose followed by 20 – 40mls per week. This ensures a background level is maintained within the pond to ensure that it works effectively. If using Extract of Barley Straw as a preventative measure, we recommend starting to dose it at the beginning of March at a rate of 20 mls per week.

Please note that the above dosages are given as a guideline, as all ponds and all algae are different and respond differently to treatment. Extract of Barley Straw is a totally natural product, so it may take a few weeks before you see the full effect. If you are not satisfied that it is working quickly enough, you can add more as it will not harm your fish, pond plants, wildlife or pets.
