Navy Blue – Organic Dye for Ponds, Lakes & Basins (Liquid & Sachet Versions)

Bleu Marine® – Naturally limits the growth of algae and aquatic plants

Bleu Marine® is a concentrated biological dye specially designed for ponds, lakes, basins, and large water bodies.

By coloring the water an elegant navy blue shade, it reduces the penetration of some of the light rays needed for photosynthesis. Algae and aquatic plants then have less energy to grow.

This action gradually limits the growth of many unwanted aquatic plants while improving the water body's aesthetics with a pleasant azure blue coloration.
