Create a stunning water feature with black pond dye

Dyofix Pond Black is a black pond dye used in smaller ponds and fountains where a dramatic effect is required.

Garden designers use black pond dye to create an obsidian black mirror reflection for a stunning garden pond design.

Sunlight, moonlight or candlelight, the black mirror finish of the black pond dye looks amazing and puts the finishing touch to your water feature.

Dyofix black pond dye halts the growth of algae

Pond Black is used in smaller ponds where the need to stop algae growth and weed growth is important. The black pond dye absorbs and blocks all daylight, allowing no light to penetrate below the surface, hence the black appearance.

Your pond plants that have leaves and flowers above the surface of the water are not affected at all by the use of Pond Black. Fish are also safe in this environment but Pond Black darkens the surface of your pond markedly, making it impossible to see the fish.


  • Blocks light, denying algae its food source
  • Enhances your pond’s reflective qualities
  • Creates a stunning mirror-like backdrop for your water plants
  • Free of pesticides and herbicides
  • Harmless to water filters and plants
  • Saves time for the weekend gardener
  • Helps create spectacular water features
  • One application can last up to three months

Liquid black pond dye

Each bottle containing 300g of black pond dye will treat up to 1000 litres of pond water. The liquid dye must be poured very carefully into the pond water to avoid splashes of concentrated dye on yourself or your surroundings.
