Water tracing dye is a safe, nontoxic, and biodegradable way to determine the direction and rate of water flow in various systems. The water tracing dye dissolves rapidly in water, producing a vivid, easy-to-see color used to trace the diffusion. Water tracing dyes are excellent for identifying diffusion and dispersion patterns, rates of flow, discharge locations, seepage areas, sea marking, and more. Tablet dye tracers dissolve quickly but are limited to small volume systems. Liquid dye tracers can be used in most any volume system, but they are the bulkiest in weight and size. Powdered dye tracers are best used in large volume systems.
