NT Labs Black Pond Dye 250ml

NT Labs Black Pond Dye provides a mirror like reflective surface to your pond, water feature or lake to help prevent the growth of unsightly green water algae and blanketweed. Black Pond Dye is commonly used by landscape gardeners and uses a safe, economical dye that restricts the light from the sun penetrating the water column, therefore cutting off the light source which causes algae and blanketweed to grow.

For best results use NT Labs Black Pond Dye in the spring before the algae becomes too established. Alternatively use NT Labs Magiclear first to clear the water. For complete control repeated doses should be added monthly as the colour fades. NT Labs Black Pond Dye is harmless to all other forms of life in the pond.
