When the weather changes during the spring season, and again in the fall, algal blooms appear in many open bodies of water. Temperature changes and seasonal winds during these periods stir the water, in turn stirring up sediment from the floor. In doing so, this adds a fresh concentration of nutrients to the water. While this phenomenon, known as the turnover process, is completely normal, it can make your pond turn a green or brownish-green color when it occurs.
At the same time as this is occurring, additional nutrients are entering the water from outside the pond. If only a minimal amount of these outside nutrients are added to the water while the turnover process is also taking place, then it doesn’t take long, only about a few weeks, for the water to clear back up. If the nutrients coming from outside the body of water are too excessive however, then, combined with the turnover, the brownish-green tint to the water could linger.
Immediate Fix: Aquatic Dyes
Fortunately, there is a method you can use to get immediate relief from those algae explosions and the unsightly brown and green water they produce: aquatic dye.
There are non-toxic dyes you can buy from pond management companies in Florida that will help keep the excessive growth of algae in your pond under control. To always be safe, never use dyes not labeled non-toxic and made specifically for use in open bodies of water. Pond dyes are similar to food dyes in that they contain colorants not found harmful to wildlife. (That said, don’t try eating pond dye or substituting it for food dye in your next batch of holiday cookies.)
If you’ve ever noticed how fresh, clear, blue and, above all, algae-free the water looks at golf courses and recreational parks, in decorative fountains and ornamental ponds, it’s because the tenders of those water bodies add an aquatic blue or blue-green dye to the water.
Benefits of Aquatic Dyes
In addition to providing that familiar, healthy tint to the water, aquatic dyes also reduce the penetration of sunlight into the water. This acts as a form of shade that helps to impede photosynthesis, thereby reducing algal growth.
Aquatic dyes are most effective for controlling blue-green algae and filamentous algae. They are not herbicides, however, and cannot be used to kill off algae that has already proliferated.
Aquatic Dye Colors
You can get pond dyes in a range of colors:
