Yeah, I am currently formulating a plan of attack to manually remove it. My problem is that the size of the pond doesn't lend itself to an 'easy' go of it. I'm probably going to have to fashion a larger 'rake / net' system to troll behind the boat and make multiple passes.

From reading the forums on FA, it seems that dying the water is a key to prevent, or at least keep at bay, future growth, by blocking out the ability of sunlight to feed what is on the bottom.

Guessing this is going to be a continuous job !!
