All Bright Dyes products are safe, non-toxic, biodegradable and certified to NSF International Standard 60 for use in drinking water .
For small amounts of water, the Bright Dyes tablets are clean and easy to use…no measuring is required. They may be dropped or flushed directly into a drain, sewer, septic system, etc., where they dissolve in about 3-5 minutes. Or, they may be dissolved in a small amount of water first.
For larger bodies of water, Bright Dyes powder or Bright Dyes liquid concentrate may be more suitable for your needs.
In the situation of a long-term flow study Bright Dyes wax products such as cakes, cones, or donuts may be appropriate.
