The Swell Water Feature Clear is an eco-friendly approach to the problem of green water, algae, blanket weed and slime in fountains, barrel features and small ponds (not containing livestock!, such as plants and fish). Regular use through the summer will help to maintain good water clarity, eliminate stagnant odours and reduce the need for cleaning.
Simply add the feature clear directly to your feature, this usually clears most features over night.
1 cap full for every 20ltrs of water in feature.
Not for use is fish ponds
