The color of the dye blocks a certain sprectrum of light rays that are
necessary for algae growth. Even in a turbid pond the blue dye does
clear up the turbidity somewhat so you do gain some visibility even
though it may be a blue color.......To me I would rather look at a
fake blue color pond and have some clarity, than look at a grey
colored pond and not have but a few inches of visibility. Believe it
or not, The dye does help reduce algae growth, as well as other
aquatic growth.


My wqater comes out a blue green color, not as blue as the dye is,
mainly to do my composition of water / clay etc, so its not a real
artificial look, as it would be if its applied to a body of water with
good clear clean water.
