Aquacadabra Vanquish Black Pond Water Dye – Algae Control for Ponds & Water Features

Aquacadabra Vanquish Black Water Dye is a highly effective and economical treatment for controlling algae growth in garden ponds and water features. Designed for use in early spring, this concentrated dye works by reducing sunlight penetration, helping to prevent algae before it takes hold.

With a straightforward dosing rate of 1ml per 1 litre of pond water, it’s easy to apply by pre-mixing with pond water in a watering can or bucket, then spreading evenly over the pond’s surface. The dye disperses naturally throughout the water column, and while it may appear darker at first, it will balance out over a short time.

In addition to algae control, the dye gives your pond a natural, reflective black tint, enhancing its depth and visual appeal.
