Howdy, LB:

Ther are many threads here on GC. Look in the "Aquatic Vegetation" sections, especially "Controlling Unwanted Plants."

You may want to wait until next year, do a little thinking and research. Are there any ponds nearby with/without GC that could give you an idea on how much plant life to expect (no gaurantees your pond will be the same, but maybe a rough guess)? What are your goals, and how does that affect how much vegetation you desire and are willing to tolerate? (Swimming hole - you probably want it pretty clean. Big bream pond - you may want to hold vegetation down to help predators eliminate BG, holding the numbers down to help growth. Big bass - you want a certain amount of cover - how much to you want to be plants, how much artificial?). Also research the threads on what plants GC eat and don't eat; compare this with any aesthetic wishes you have wrt plants (water lilies, etc.).

Like ML said, you don't want too many GC. One at a time is likely to be plenty in 1/3 acre. However, I would be much less afraid of getting behind the weeds and having to play catch up with extra GC with a small pond than with a multi-acre one - even a high density of GC for you would be maybe a half a dozen, which should be easy to reduce if desired.
