I want to use one of those beautiful large glazed ceramic pots to make a fountain. It would be a large one so that the top will be at a decent elevation - something on the order of five or so feet high. I guess it would have a 50 - 70 gallon capacity, depending on the shape. I want to have the water bubble up over the top and run down the side. I figure I will bury a plastic tub in the ground, center the pot in the tub and fill the tub with large decorative round stones. The overflow would make its way to the tub where it must be pumped back to the pot. Here are my questions. Where should the pump go? At the bottom of the pot - with a long extension tube to provide the bubbling action at the top and tubing that passes through the bottom side of the pot to the tub area to suck the water? Near the top of the pot, perched on something with the tubing (and power cable) going down the pot and out? Don't need the extension in this case. Or possibly in the tub? Should it be a 120v or low-voltage pump? Now for the biggie, what size pump would I need? I'm not looking for Niagara Falls - just want a nice steady bubbling over that I could hear inside. This will be right outide my window along my front walkway. Maybe a variable flow would be helpful. How much would the pump cost? I know the pot will be very expensive. Any other considerations, ideas, etc.? Obviously I have to get to an electric outlet as well. Thanks.
