Blue Water Junior 250g is a powerful, natural water treatment solution formulated to tackle algae blooms, blanket weed, green water, and organic sludge in ponds and lakes. Unlike traditional pond chemicals, Blue Water Junior uses a blend of beneficial bacteria, enzymes, buffers, and dispersing agents to restore water clarity, reduce odors, and create a healthy aquatic environment.
This eco-friendly product works by removing the nutrients algae thrive on – nitrates and phosphates – helping to prevent reoccurrence of green water and excessive weed growth. Regular use also helps reduce organic silt buildup on the pond bottom, supporting long-term water health and reducing the need for costly manual cleaning.
Safe for fish, amphibians, aquatic plants, and all pond wildlife, Blue Water Junior is ideal for use in garden ponds, ornamental water features, and small lakes – with no harsh chemicals or environmental side effects.
