Start out by sealing each clay piece with a spray water sealer like Thompson's. Apply at least two coats. Let dry thoroughly between each coat.
Next, select a level spot. As you can see from the picture, we flipped a whiskey half-barrel upside down and used that. Place the 10" saucer on top of the 9" bowl.
Attach the pump to the tubing. Wet the 10" saucer a bit and stick the pump to the saucer in the desired spot.
Take the 6" pot and etch a small notch in the top lip of the pot. Now flip the pot upside down and place it over the pump, pull tubing through the drainage hole, and position the pump power cord under the notch.
Take the 6" saucer. Cut a small hole in the center of it with a masonry bit, large enough for the tubing to run through. Flip the saucer upside down and place on top of the 6" pot. Cut the tubing to size.
Place the 3" bowl on the 10" saucer, fill the 10" saucer with water, decorate with gems and rocks, plug in the pump and enjoy. Add more water as necessary.
