Blackout is a highly concentrated black lake and pond colourant which transforms pale, off coloured water to a decorative, mirror like black colour without harming or discolouring fish, waterfowl and animals.

Blackout creates the perfect colour for lakes, ponds, water hazards, or large fountains. In addition, Blackout’s specialised blend of pigments and dispersing agents act as a shading barrier on the surface of the water to inhibit algae’s main food source - ultraviolet light, whilst allowing other light sources to pass.

Key points:

  • Creates a natural looking water feature with excellent reflective properties
  • Quick effect
  • Creates unfavourable conditions for algae
  • Can be used in irrigation lakes
  • Low toxicity
  • Inexpensive to use


Application Rate:2.5 - 5 litres per hectare of surface water
