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.

While there’s always a possibility that pests will appear in and around a natural swimming pool—much like regular swimming pools—they largely deter pests due to their natural filtration system, which keeps things clean and the water constantly moving.

Although we often equate bodies of water with pesky mosquitoes, you don’t have to worry about them in your natural swimming pool. This is because mosquitoes are attracted to bodies of standing water. Your natural pool, on the other hand, has consistently moving water, thanks to the pump that runs all year long.

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.
