I have a little bit of FA in the early spring, covers less than 25% of the pond. I was considering possibly adding some dye to the water. The pond gets medium amounts of sun during the day, it is partially protected by trees on almost 3 sides. I have some lily pas and a mat or two of surface weeds but it is not out of control.

I was hoping the pucks would get me started and then I intend to put in a couple diffusers on the bottom.
