Fountains questions, answered by experts

Deep clean your koi pond at least once a year to keep your fish healthy and your pond in good shape. Water testing, debris removal, and partial water changes should be performed weekly. Seasonal professional service will ensure everything is clean and functioning properly.

When deep cleaning your koi pond, transfer fish to a clean, uncontaminated container at least one foot deep, like a large bucket, tub, or kiddie pond. Fill the container with their existing pond water to avoid shocking them, and place the container in full or partial shade. When it’s time to reintroduce them into the pond, slowly add the new water to the container before adding the fish and container water back into the pond.

Pond installation costs typically range from $1,500 to $10,000. The final price depends on several factors, including the pond's size, the materials used, excavation requirements, and any additional features such as waterfalls, lighting, or specialized habitats for fish like koi.

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.

To maintain your pond, you’ll need to occasionally clean your backyard pond, especially if you have koi fish. Test the water twice a week to make sure your fish have everything they need and always remove visible debris.
