Ponds are an attractive landscaping option and a way to raise fish, but they require maintenance just like other portions of the home. Removing organic debris, such as leaves, fish waste and unwanted algae and plants is critical to keeping the water clean. Once way to remove this material is by using a pond vacuum. These vacuums work much like a sump pump by sucking up material and depositing it outside of the pond.
Attach the appropriate nozzle to the end of the pond vacuum wand, depending on what you are removing. If you are cleaning rocks, use the crevice tool. If you are cleaning the entire bottom, attach the wider mouthed tool. Refer to the vacuum's user guide for details on each attachment.
Extend the outflow hose to an area of the yard where you will deposit the debris and water, such as a ditch. Some pond vacuums have a mesh bag that you tie securely over the end of the hose which catches the debris so you can throw it away. If your vacuum has this bag, install it.
Plug the cord of the vacuum into an outdoor electrical socket, using an outdoor approved extension cord, if needed.
Insert the end of the vacuum wand into the pond and turn the machine on. Vacuum out all unwanted debris from the pond, changing out the attachments as needed until the pond is clean.
Some vacuums use only a garden hose and do not require that you plug them in. However the suction is not as powerful on these models and they do not work deeper than 3 feet.
