What I did not see in his reply is how much work "harvesting" that stuff is. It is very heavy. I drug a lot of it out and loaded it into a trailer one year. Was not a lot of fun. Does build muscles though, if it doesn't break your back first.
I think on the second page are pictures of the rake I made from a landscape rake to pull it out of the pond that worked pretty good.
