i have a 3/4 acre pond and duckweed covers it entirely. when i first got the property i got some grass carp, but later found out that they may not like duckweed, well they must not because it's as bad as it ever was.
i've tried doing some skimming to get rid of it but i can't make a dent.
my fear of using chemical treatment is the expense and the fact that it may come back. how do you know you got it all and is there a fish that does eat it? that way if it starts coming back the fish will eat it before it becomes a big problem again? i read about fluirdone, i've never heard of that. i've been looking at tsumani(diquat) and it will cost me over $500. is fluirdone better or cheaper?
sorry for all the questions. i have a lot of them
