Small Goldfish Ponds Made Easy: A Beginner’s Guide

A Beginner’s Guide

The shimmering allure of goldfish has captivated hearts for centuries. Traditionally kept in glass bowls, these vibrant fish can now thrive in beautiful, low-maintenance ponds, offering a splash of life and color to any garden. Small preformed ponds are a perfect solution for beginners, providing an easy and affordable way to bring the joy of goldfish ownership into your own backyard.

The Allure of Small Goldfish Ponds

Forget the limitations of a cramped fishbowl. Small preformed ponds offer a world of opportunity for your goldfish. These hardy creatures will flourish in a thoughtfully designed goldfish pond, displaying their playful antics and stunning colors for years to come. Unlike their larger cousins, koi, goldfish are well-suited to the confines of a small pond, making them ideal for those with limited space.

Choosing the Perfect Preformed Pond

The first step to creating your goldfish paradise is selecting the right preformed pond. These come in a variety of sizes, shapes, and materials, allowing you to find the perfect fit for your aesthetic and space constraints. When making your choice, consider the following factors:

• Size: While goldfish are adaptable, they still need room to swim. A good rule of thumb is to allow one gallon of water per inch of goldfish length when mature. So, for two small goldfish that will grow to be 4 inches long, a minimum pond size of 8 gallons would be ideal.
• Depth: Aim for a pond with a depth of at least 2 feet. This provides cooler water during hot summers and helps to prevent the pond from freezing completely in colder climates.
• Material: Preformed ponds are typically made from fiberglass, plastic, or polyethylene. Each material offers its own advantages and disadvantages. Fiberglass ponds are strong and durable but tend to be more expensive. Plastic and polyethylene ponds are lightweight and affordable, but may not be as UV-resistant.
• Shape: The shape of your pond is largely a matter of personal preference. Round ponds offer a classic appeal, while more natural-looking kidney or rectangular shapes can blend seamlessly into your garden design. Some preformed ponds even come with built-in shelves, providing ideal planting zones for aquatic plants.

Finding the Ideal Location

Once you’ve chosen your preformed pond, it’s time to find the perfect spot in your garden. Here are some key factors to consider:

• Sunlight: Goldfish and aquatic plants both benefit from several hours of direct sunlight each day. However, avoid placing your pond in full sun all day long, as this can lead to excessive algae growth. Aim for an area that receives a mix of sun and shade throughout the day.
• Trees: Avoid areas with overhanging trees. Falling leaves can decompose in the water, leading to water quality issues. Additionally, tree roots can damage the pond liner.
• Underground Utilities: Before digging, it’s crucial to call your local utility locating service to ensure you won’t strike any underground lines.
• Wind: Consider prevailing winds in your area. A strong wind can disturb the water and make it difficult for the pump to function efficiently.

Preparing the Site

With the perfect location chosen, it’s time to prepare the site for your preformed pond. Here’s what you’ll need to do:

1. Mark the Outline: Use spray paint, sand, or a garden hose to mark the exact footprint of your preformed pond on the ground.
2. Dig the Hole: Dig a hole slightly larger than the pond itself, allowing for a leveling sand base. Ensure the hole is level by using a spirit level.
3. Remove Obstacles: Carefully remove any rocks, roots, or sharp objects from the bottom and sides of the hole to prevent puncturing the pond liner.
4. Level the Base: If the ground is uneven, you may need to remove excess soil or add compacted soil to create a level base for your pond.

Installing the Preformed Pond

Now comes the exciting part – installing your preformed pond! Here’s how:

1. Sand Base: Place a 2-inch layer of damp sand over the leveled base. This sand layer creates a smooth, protective cushion for the pond liner.
2. Liner Placement: Carefully lower the preformed pond liner into the hole, ensuring it unfolds smoothly without any tears or punctures.
3. Level Check: Once the pond liner is in place, refill the pond with a small amount of water and check for level again. You can use a spirit level placed on the rim of the pond.

The water pressure from the inside will help push the sand snugly against the liner, creating a secure and supportive base for your pond. Here’s why using sand is important:

• Drainage: Sand allows for better drainage compared to soil. This is crucial because trapped water behind the liner can cause the liner to bulge or even rupture.
• Weight Distribution: Sand distributes the weight of the water more evenly, reducing stress on the liner.
• Settling: Sand settles more uniformly than soil, minimizing the risk of uneven settling and potential liner damage.

4. Backfilling: Slowly fill the pond with water while simultaneously backfilling the space around the pond with sand (not soil) to provide support for the liner. The water pressure from the inside will help push the sand snugly against the liner.

Adding the Finishing Touches

Now that your preformed pond is in place and filled with water, it’s time to add the finishing touches:

• Hiding the Liner: Conceal the exposed liner edge with decorative pond edging stones or pre-formed edging kits. This not only adds a polished look but also helps to secure the liner in place.
• Liner Underlay (Optional): For added peace of mind, consider installing a liner underlay beneath the sand base. This underlay provides extra protection against punctures from rocks or roots.
• Planting Aquatic Plants: Aquatic plants play a vital role in a healthy goldfish pond. They not only add beauty and a natural feel but also help with filtration by absorbing nutrients and competing with algae for growth. Plant marginal plants (shallow water zone) and submerged plants (deeper water zone) for a variety of textures and colors.
• Filtration – A Must for Goldfish Ponds:

One crucial element you cannot overlook is filtration. Unlike a self-contained aquarium, a small pond relies on a filtration system to maintain clean and healthy water for your goldfish. Goldfish waste produces ammonia, which can be toxic in high levels. Here’s where filtration comes in:

• Biological Filtration: A simple box filter containing bio-media provides a home for beneficial bacteria that convert harmful ammonia into less toxic nitrites and nitrates. These nitrates can then be absorbed by aquatic plants.
• Mechanical Filtration: Some filters also offer mechanical filtration, which removes debris like leaves and fish waste from the water, keeping it clean and clear.
• UV Clarifier (Optional): If you find your pond turning green due to suspended algae growth, a UV clarifier can be a helpful addition. This device uses ultraviolet light to kill algae, keeping your pond water sparkling clear.

Goldfish Care in Small Ponds

While goldfish are known for their hardiness, proper care is essential for their long-term health and well-being in your small pond:

• Stocking Density: Avoid overcrowding your pond. Remember, the rule of thumb is one gallon of water per inch of goldfish length when mature. Overstocking can lead to poor water quality and health problems for your fish.
• Feeding: Overfeeding is a common mistake. Feed your goldfish a high-quality diet appropriate for their size only 2-3 times a day, providing only what they can consume within a few minutes. Uneaten food decomposes in the water, adding to the ammonia load.
• Water Quality: Regularly monitor your pond’s water quality using a test kit. This allows you to take corrective action if ammonia, nitrite, or nitrate levels become too high. Partial water changes can also help maintain water quality.

By following these simple guidelines, you can ensure your small goldfish pond thrives and provides you with years of enjoyment. Remember, goldfish are social creatures, so consider keeping them in groups of at least two or three.
