Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants weed and grass question

Ok, here's what I have done. I added a coupling to my 4 inch overflow pipe this past summer while my water was down. It raised my waterlevel about 5 inches or so. But now the grass which was on the bank is in the water of course, I figured it'd just die but most of it hasn't. What can i do to kill it? I believe we sowed Kentucky fescue if i remember correctly, possibly Bermuda, I'm not sure. I'll find out though. I also have some small willows starting about a foot or two from the waters edge. I pulled these up last summer but they're back. I also have so algae growing near the bank. I added 10 grass carp about 4 years ago, I used to see them alot near the top and they were growing pretty good but havent seen them in about 2 or 3 years and thought they had died or something, i did find two dead lying against the bank 3 years ago. Last weekend I saw 4 of them suddenly reappear on top of the water, about 2 1/2-3 ft long. Why haven't i saw them for the last few years now they are suddenly back????? I will have to figure out how to add pics on here when i get a chance. Any help is greatly appreciated. Thanks!!!

Keven, I expect the grass will die. It USUALLY does.

Willows are seldom eradicated. They are continuing maintenance. Every year, I either pull them or spray them.

If you have what you consider vegetation problems, you may need some new grass carp. When they get big, their appetite seems to decrease.

How many grass carp do you recommend per acre of water?
