Pond Clear is a brilliant, natural way to clean the water of your pond. As the barley straw reacts with water and sunlight it begins to slowly decompose, producing humic acid which eventually leads to the release of low levels of hydrogen peroxide.
Depending on the weather and pond conditions, this natural method can take up to a period of several months to complete, so be patient.
Barley straw works best in high-oxygen, well-aerated, and algae-free ponds as it’s free to decompose quickly and more efficiently. For this reason barley straw is first best used as a preventative measure.
Algae can be combatted also with a balanced selection of aquatic plants and molluscs. Bear in mind that low levels of algae are generally good for a healthy pond.
One box of Pond Clear is enough for a small sized pond.
