Mr Koizumi Green Control Water Treatment

Mr Koizumi Green Control – 2.5kg & 5kg (5kg Pack Contains 2 x 2.5kg Bags)

Mr Koizumi Green Control is a 100% natural pond water improver designed to enhance water quality, promote healthy fish, and naturally reduce algae and blanketweed growth — often making chemical anti-algae products unnecessary.

Formulated with mineral-rich natural ingredients, Green Control works to rebalance pond water, improve clarity, and stabilise oxygen levels, creating the ideal environment for fish and plants to thrive. Regular use supports vibrant fish colouration, boosts appetite, and encourages overall pond health.

Unlike many traditional treatments, Mr Koizumi Green Control is completely free from algicides, biocides, zinc oxide, and copper compounds, making it safe for all pond life, pets, and even swimming ponds. Its phosphate-free formula helps prevent excessive nutrient build-up — reducing the conditions that allow algae and blanketweed to return.

Green Control can be used throughout the year and remains effective even at temperatures below 10°C, ensuring your pond stays healthy during cooler months.
