Otto,
I should have been more specific when I stated 'submerged grass'. I'm thinking of planting milfoil or hydrilla or coontail moss to the fish have some more cover. I don't know anything other than a biolist told me not to. But every 'Great' bass fishery I've been to has some sort of submerged grass. With my pond being deep, I could just draw it down 5-6 feet if the grass ever became a problem and kill it. What do you think?

I started with nothing, and still have most of it.
