Pond Boss Forums POND CONSTRUCTION Selecting a site Pros and Cons of pond shape

I like an even more irregular shaped pond, points, etc.

But back to your query. In my opinion, the only drawback is that the L shaped pond will require more $$ to have a properly designed aeration system in it due to it's shape. Oval/rectangular/square ponds are easier. Just due to their shape and how the diffusers move water.
