This robust water bowl is a decorative addition to any pond. Fill the round bowl with marsh plants and enjoy the subtle waterfall created by the included pump. The water is fed through the filter material and the bowl is filled with clean water. The water falls over the edge back into the pond, while dirt particles remain in the filter chamber. With an additional water reservoir, the water bowl can also be used without a pond. This decorative water bowl is a unique addition to your garden and provides a beautiful backdrop for your pond. With the pump and filter material, you can be sure that your pond will always have clean water.
