I have put dye in before. Mainly was just playing. Found it at the farm store. Turned my whole pond bright blue. It was pretty cool. My issue with it is I want to be able to see the fish. Im not against any method besides dragging it all out by rake. I did some of that (basically just a workout) and it was right bk the next day. I do have some plants started and will add more this spring. Thank you for all the ideas hopefully this will helps others as well. Is there more fish that will eat it also? I see that crawdads will consume some. Not sure how many millions it would take to eat all of this stuff.
