Will do. I have access to acres of standard eel grass, but am very reluctant to add it to my lake. We've fished it often, and it's great, but it does require deeper water and grass carp to control. (That's just personal experience here in East TX)
I found the corkscrew at various aquarium stores, and $1 a plant seems to be the average price. My plan is to plant it on the dam where, 1) the water drops off quickly, and 2) I can make an end run on it if it spreads to quickly.
I'll plant early this Spring and repost.
