Fountains questions, answered by experts

Like pools, ponds can be a safety risk, so they may increase your homeowners insurance. Be sure to let your insurance company know if you build a pond on your property—they may have safety requirements in order to keep your premium from increasing. 

Small ponds can be drained and filled in about a day. Larger ponds will take two or three days for professional removal.

DIY kits are available, but professional installation ensures proper water flow, electrical safety, and leak prevention.

A good rule of thumb is to change 5% to 15% of your koi pon’s water every week. Partial water changes help keep your koi healthy, and replacing small amounts at a time prevents causing stress for the fish.

The average pond maintenance cost is $2,000. But how much you pay to take care of your pond depends on multiple factors, such as the size of the pond and whether fish live in it. Your area's climate also affects the overall maintenance cost, as you may need to winterize your pond to protect it and any aquatic life in it during the colder months.
