Pond dyes work by coloring and tinting the water a shade of dark blue, black, or blue-green. Tinting your pond water not only covers the brown or greenish look, but it acts as a sunscreen for your pond or lake, keeping out excess sunlight. UV rays can damage your beneficial bacteria.


When using Beneficial Bacteria Products it is a good idea to use pond dye to block excessive sunlight that would harm the bacteria you are trying to propagate to consume your excess muck and organic nutrients.

When do you Apply Pond Dye?

Aquatic pond dyes should be applied in early Spring. March and April applications are best. In southern states, pond dye is often applied year-round.


How do you Apply Pond Dye?

Application of pond dye is as easy as pouring the dye into the water or throwing it in a pond dye toss pack. Your pond dye will quickly spread throughout the pond, usually within a few hours. If you have a fountain or aerator you should run it during application. Pond dye and lake dye will naturally diffuse throughout the water and there is no need to use a sprayer to spread out the application evenly. Pouring the dye directly from the bottle at three or four spots around the shore is sufficient.


Be careful! When applying the undiluted pond dye concentrate will stain clothing and skin, but once diluted in the pond or lake, it will not stain. Smith Creek now carries Water Soluble pond dye toss packs to make the application faster and cleaner!

The initial spring application will begin to fade, within a month or two, as runoff from rain dilutes the dye concentration. Gradually color is lost due to photo-degradation and biodegradation because the dye is an organic compound. As the dye fades, “touch-up” applications may be needed. Maintaining the correct level of blue color throughout the season. Professional quality dyes, that are EPA registered, can be easily purchased online where legal or applied by certified aquatic applicators in your area. ***Pond Dyes are not pesticides and should not be considered an alternative to EPA registered pesticides. Summary The key to effectively using pond dye is to make the initial application early and continue to add more pond coloring as needed throughout the season.
