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.

Algae growth is a common issue for misters, but you can do several things to prevent it. First, use a sealed water tank with distilled or filtered water to fuel your misters. Second, blow out the misters after every use so no water is left in the tubing. Third, thoroughly clean the misting system every several weeks of use at minimum during the warmest months. Third, wherever possible positioning tubing and the water tank away from direct sunlight and in the coolest areas possible.

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.

Even if you empty your pond before the winter, there’s a good chance it will refill naturally. It’s ideal in most cases, then, to leave water in your pond and winterize it instead. This method will prevent ice damage and protect wildlife. Plus, it’ll lessen the steps required to reopen your pond in the spring.
