big, I love grass in my pond. There, I said it.
Problem is we get Chara, Naiad, and Coontail, etc. here in TX, and they are very invasive, and can be hard to control. The long growing seasons don't help either. I know for a fact that Naiad can grow deeper than you can clearly see, so it doesn't take a lot of light to keep it growing.
Take some pics, both in and out of the water. Put the out of the water pics up against a sheet of printer paper, and let's see what you have first.
Perhaps after you post some pics, Kelly Duffie will chime in. He's as good as there is, and he's based in South TX.
