These filters can be recessed into the ground, placed at the top or bottom of a waterfall. Unlike submersible filters, they do not take up space in the pond or detract from the beauty of your pond.
Spare Me! Keep a spare air pump or water pump on hand for emergencies. If your pump ever stops, do not feed your Koi.
Consider using seperate water pumps for your waterfall and filter. This way you will always have a backup, and you can save energy.
