Blue Water Soluble Sachets offer a simple, mess-free way to manage algae and blanket weed naturally in ponds, lakes, and water features. Each 250g water-soluble sachet contains a powerful blend of beneficial bacteria, enzymes, buffers, and dispersing agents that dissolve in the water and get to work quickly—targeting the root causes of algae growth.

By safely removing excess nitrates and phosphates, these sachets prevent algae blooms and green water, reduce silt build-up, and eliminate odours caused by decaying organic matter. Safe for fish, aquatic wildlife, pets, and plants, Blue Water Soluble Sachets are a chemical-free solution suitable for both residential and commercial aquatic environments.

Available in 8, 25, or 50 x 250g sachets, this format is ideal for larger ponds, lakes, or long-term treatment programmes.
