🌬️Insulate your pond with building sand and insulation to regulate temperature and protect the fish during winter months.

🛠️Clad the pond and filter with decking boards for a beautiful and cohesive look, while adding structural support.

Why is filtration important in a goldfish pond?

—Filtration is crucial for maintaining water quality by removing debris, waste, and harmful substances. It keeps the water clean and provides a healthy environment for the fish.

What is a bog filter and why should I use it?

—A bog filter uses rocks and gravel as filtration media, creating surface area for beneficial bacteria to grow. Additionally, it allows you to grow plants that help further filter the water and enhance the aesthetics of the pond.

Why do I need to insulate my pond?

—Insulating your pond helps regulate temperature and protects the fish during colder months. It prevents extreme temperature fluctuations and provides a more stable and comfortable environment for the fish.

What are the benefits of sinking the Pond into the deck?
