Fountains questions, answered by experts

Regularly clean pumps, remove debris, and monitor water levels to prevent algae growth and clogging.

A koi pond should be at least 5 feet deep to keep the fish healthy and ensure they don’t freeze in winter. Koi fish are also known for growing large, so the more room you have, the better. A larger koi pond size will allow the fish to grow bigger than a smaller one will, and the more fish you have, the bigger the pond you’ll need. Learn how to build a pond in your backyard to ensure it remains functional and aesthetically pleasing for a long time.

DIY kits exist, but professional installation ensures proper filtration, landscaping, and leak-proof construction.

Placing your water feature in direct sun can speed up evaporation, leading to pump damage and algae growth. Shade or partial shade serves as the ideal location for most water features—just watch out for tree and plant debris that may fall in and clog the pump.

How many fish can call your pond home depends on the volume of the pond and the fish size. Your pond's filtration system also influences the number of fish that will thrive in a pond. A general rule of thumb is to have 1 inch of fish for every square foot in a pond that's 2 feet deep. Another rule of thumb you can follow is to have one koi fish for every 200 gallons of water or two goldfish for every 200 gallons.
