Wow Cecil. I have a little spot of chara in my minnow pond, and had no idea it was such a milignant pest. I'm sure there's none in my main pond yet, because it's never cleared up since I built it. I'm going to pull all the chara out of my minnow pond, and watch it carefully in my main pond. I may get some GC for preventative measures. Thanks for the warning!
Bobad,
I have a lot of nutrients from the fish I feed intensely for grow out. More than a typical recreational pond. So you may not have it grow as prolifically as it does for me.
