3 Key Considerations When Adding Fish to Your Swim Pond

With the right knowledge and proper planning, any pond owner can enjoy the many benefits of a swim pond inhabited by fish. Before adding fish to your swim pond, it is crucial to consider the following elements:

1. Water Cleanliness

Keeping your water clean should be a top priority whether your pond has fish in it or not. Failure to keep your pond clean can result in increased cleaning requirements, an imbalanced ecosystem, and poor fish health. In severe cases, your pond may need to be thoroughly cleaned via chemicals or other treatments before adding fish. Swim ponds and natural pools can be kept clean via biological filters, circulation systems, water gardens, proper care, and the fish inhabiting them. A professional can work with you to provide tailored recommendations for your specific pond needs, ensuring optimal water clarity and health throughout the year.

2. Fish Population

While many different types of fish can be added to a swim pond, it is important to maintain a healthy, balanced population. Overpopulation can quickly compromise the health of your water garden due to the lack of zooplankton and an excess of fish excrement. Underpopulation can also be detrimental to your pond as it can lead to an excess of algae that can be harmful to fish. To keep your fish population balanced, it is best to have no more than 1 6” fish for every 100 gallons of water.

3. Ecosystem Balance

In addition to balancing the fish population, you will need to consider the balance between your new fish and the water garden. Also known as an aqua garden or plant shelf, this garden consists of several plants that naturally filter the water, making it a vital component of a clear and healthy pond. While fish can help keep your pond balanced, they can consume the insects and zooplankton these plants require for survival if left unchecked. To keep your ecosystem balanced, it is often best to ensure that your water garden is not accessible to your fish. An effective method of separation is to place your aqua garden on one level of your swim pond while keeping fish at a lower level. This will help keep your pond balanced without exposing your plants to hungry fish.
