Hi,

Thanks for your kind comments..

The general rule is that you would like a pump that turns over the pond volume roughly once per hour, although less is ok on larger ponds.

Depending on how much water you would like to move, and how strong of a waterfall - I would recommend a 5,000 to 10,000 gallon per hour pump. However, I would definately recommend using an energy efficient external pump vs. a submersible pump.

Submersible pumps burn up to 5 times as much energy, and can really run up your bill. Our best high flow pond pumps are the Artesian and the Dragon pumps, which you can view here:

For filtering your pond, we recommend an Aquabead biological filter system:
