I've finished building my pond (18'x18'x2'/attached to a 55' long 2' wide
stream up to a waterfall at a grade 4 feet above the pond grade).

There are so many pumps on the market. I do not know where to go. I do want
a good flow of water to make the waterfall dramatic. Does anyone care to
advise me on what pump I should obtain? I would want a pump which is under
the water. I would want this pump to be effecient, using less energy than
some pump. Are there any good solar pumps?

There will be a lot of plants and few fish in this pond.
Thanks so much for any help.
