Feng Shui is based on the interplay of the energy of water and wind, complemented by light, earth and fire. In the garden, a fountain provides the energy of water. Fountains range from those that are complex and could compete with the water features in Las Vegas to those that are simple and minimalist.
Prepare the planter/vase. Seal all but one of the drainage holes in the bottom of the planter/vase. Widen the remaining hole, if necessary, so the tubing will barely fit through it. Thread the tubing through the hole until it reaches nearly the top of the vase. There should be enough tubing left at the bottom of the vase to reach the pump without kinking. Seal the space between the tubing and the sides of the hole. Let sealer dry per manufacturer's directions.
Dig a hole where the fountain will be located that is an inch or two shallower than the base container is tall. For example, if the container is 10 inches tall, the hole will be 8 inches deep.
Assemble the parts of the water feature. Place the base container in the hole. Place three bricks in the container and the prepared vase on top of the bricks. Attach the tubing from the vase to the pump, which should be behind the vase so it's not visible. Place the river rocks in the base container up to the top, being careful not to place any directly on the pump. Cover the exposed lip of the container and the ground around the container with river rocks as well. Fill the base container with water, making sure the pump is underwater. Fill the vase with water.
Turn on the pump and enjoy the bubbling fountain.
Mini Water Fountain

Set the base container directly on the ground or patio.
Assemble the fountain but fill the base container with only one layer of river rock on the bottom.
