Pond Boss Forums AQUATIC VEGETATION Balance of plants in the environment Accelerating Probigation of cat tails and Lilies?

I have a new 1.5 acre pond which is now just getting through the first summer season. So far the only significant aquatic weeds in it are some algae. I'd really like to accelerate (Plant & spread) some lilys and cattails. Are there any fast ways to do this? Waiting for mother nature could take a LONG time at this rate.
