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.

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.

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.

Fountain maintenance is an important part of having a clean foundation in the first place. To keep your fountain water clean, you can use a water additive designed specifically to limit scale, algae, and other buildup in fountains. Or opt to use white vinegar as a pantry-ready water additive.
