Aquatic weeds and algae can be very problematic in garden ponds and lakes. An environmentally friendly, non-toxic way of preventing algae growth is to use Hydra's Blue water dye. It is a highly concentrated liquid dye that not only produces aesthetically pleasing results; it also stops the sun's UV rays from penetrating the surface of your pond. Algae and weeds need sunlight to grow, therefore by limiting the amount of UV light that enters the pond, you are dealing with one of the factors that contribute to algae growth in your pond. Hydra liquid blue pond dye is commonly used by hotels, commercial premises and everyday pond owners.
