I'm very impressed with the pond, seems to be a good design. I'm am curious though... what are your plans in terms of decor? Will you be growing any live plants in the above and below the waterline? Any driftwood emerging from the water?
Then what type of lighting is being used? I read that you have a 30ft ceiling so I'd imagine that you're either satisfied with lower light levels(I'm sure the rays are too), or you'll be using some hanging pendant type lights over the pond.
