Ok I think will take everyone's advice and not go that route.
Answers to some questions and history.
Pond is 1 acre in size
Yes I have tried dye. I have already died it three times this year. I have home built aerator that does not seem to effect anything other than possibly help keep the fish alive.
I have only used the blue die in the past. I may try the black dye next.
I was able to wipe out the duck weed in past years with expensive fluridone treatments but the filamentous algae grows so fast and so thick that its impossible to control with chemicals so far (covers the whole pond in a week or so). We have manually cleared it with kids swimming across with a rope and dragging it to one side and then used a floating rake to pull it out. This is a huge amount of work and it grows back fast.
