Aqua shading type products, are they OK?
A. I like the look of a “little” dye in the water, I use only 10-25% of the labeled rate with proper aeration. When you block the light and negatively change the environment for one plant you also create a favorable environment for another, some plants thrive is shade and now you’ve created it. Use pond dyes as an aid in a total programmed approach to your pond or lake and not a major component expected to control problem situations.
