Aquacadabra Blue Pond Water Dye – Prevent Algae in Ponds & Water Features

Aquacadabra Blue Water Dye is an economical and effective treatment that helps prevent algae growth in garden ponds and water features. By subtly tinting the water blue, it limits sunlight penetration, making it harder for algae to grow. Ideal for use in early spring, this liquid dye supports long-term water clarity and appearance with minimal effort.

With a simple application of 1ml per 60 litres (13 gallons) of water, the dye disperses easily and safely. Pre-mix it with pond water in a watering can or bucket, then pour evenly across the pond surface. Over a few days, the colour balances throughout the pond, enhancing its appearance while working to suppress algae.
