Pond Boss Forums INTRO Questions & Observations WATER DYE

BLACK ONYX LAKE COLORANT (manufactured by Becker-Underwood) is available in both liquid (gal) and water soluble packets (16/cs). It is NOT marketed as a deterent for weed and algae growth. Instead, it is simply a "aesthetic-enhancement" option over the traditional blue pond-colorants, and one that many folks prefer to the appearance of vivid blue. In some situations (and with some experimentation), the combination of blue and black colorants at lower respective rates yields appealing and functional results - and at a lower total cost.
