Under what water conditions are dyes not recommended for use?

Dyes are not recommended for use in muddy water with suspended particles because the turbidity can interfere with the dye's effectiveness and visibility. When water is murky due to suspended particles, the dye may not disperse evenly or may become too diluted, rendering it ineffective for marking or controlling aquatic vegetation. Additionally, the particles may absorb or scatter the light, reducing the impact of the dye and leading to inadequate treatment of the water.

In contrast, other conditions like clear stagnant water may allow for better dye visibility, as the dye can disperse more evenly. In deep water bodies, dyes can also be effective if the goal is to mark specific areas or control growth; the depth is not inherently prohibitive. High salinity areas may pose challenges for certain products, but this does not specifically relate to the effectiveness of dyes in the same manner as turbidity does.
