Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Pros and Cons of Pond Dye

Muddy water affects the surface and extreme shallows temperature more on hot days, but not much impact, if any, on total absorption. I wonder if black dye would have much the same effect? I have experienced this myself from wading in very shallow water: On a hot summer day, shallow muddy water will be MUCH warmer than shallow clear water.

Edit: From my experience, the blue dye does reduce visibility (secchi depth). I have no experience with any other dye color.
