Adding an aquatic dye for lakes and ponds help filter out UV sunlight while creating an aesthetically pleasing appearance to the pond. Algae and submerged aquatic 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 and unwanted plant growth in your pond. CanadianPond liquid pond dye is commonly used by hotels, golf course, commercial premises and everyday pond owners. It will not stain birds, fish, plants, swimmers, pets, or wildlife when applied at the recommended rate.

We have clients from coast to coast who use pond dyes as part of their regular pond maintenance regime. Apply early in spring when the ice leaves the pond. CanadianPond dye will immediately block the UV rays needed for many of those unwanted aquatic plants. Farmers in British Columbia, Alberta, Saskatchewan use our CanadianPond pond dyes in dugouts to keep them weed free. Pond owners from Manitoba, Ontario, Quebec and the Maritimes combine the blue and black dyes to get a deeper colour that reflects light sharply and blocks the light needed for plant growth. By applying the dye regularly throughout the growing season, important stages in plant growth including reproduction and tuber development can be weakened. This is why we recommend regular dye applications even into the fall.

Farm ponds, canals, reservoirs, tanks and drainage systems can be severely impeded with clogged aquatic weeds. An overabundance of unwanted aquatic weeds can impede flow and reduce the amount of water entering canals or critical drainage systems. Too many weeds can alter habitat and reduce indigenous fish species. They can also interfere with boat navigation and reduce aesthetic value. Repeated applications of CanadianPond AQUA or CanadianPond MIDNITE in closed systems will interfere with the reproduction cycle of many troublesome aquatic weeds. For best results, this product should be used with beneficial pond bacteria and lake bottom aeration. Often the weeds are there because there is an abundance of organic sediments and nutrients that make conditions for growth ideal.

      Excellent Product

      I purchased the Natural colour of the dye.
      I was skeptical that it would be enough as our pond is 147 ft x 75 ft. I used a bottle and a half and it worked beautifully. The colour of the pond is gorgeous. I will probably have to add another bottle soon, it has lasted about 6 weeks.
