Cleaned out my pond middle of last year with a 360 and its now got loads of weeds growing in it . Anybody know what they are as I can't really see anything similar on the net. Also, anybody have any good ideas on how to get rid, or at least reduce/control? Someone said it was duck weed, but I thought that was the green stuff that floats on the surface that you can scoop out, whereas this stuff is rooted from the bottom and grows up. I did have ideas of putting some fish in it at some point. Its fed via a land drain and overflows out and eventually into a river.
