Snipe, would you please explain your opposition to chara? I have none in my pond, but was considering finding some and transporting here in hopes that it might add diversity to the solid stand of elodea festooned with FA that torments me this time of year.
I've been dragging the pond with a heavy rake pulled by my quad. In addition to the elodea, I'm starting to pull in a pondweed that looks suspiciously like sago. The deeper water also has a grasslike plant that grows in small clumps of 5 to 20 sprigs about 3" tall. This last one doesn't show up on the TAMU nor other sites. Since you and I live in somewhat similar regions, have you seen this clumping plant?
Grass carp, I have 6 in a quarter acre, scarcely put a dent in my vegetation.
