FAQ
What’s the typical lifespan of a 120L resin pond?
Most 120L resin ponds have a lifespan of approximately 5-10 years with proper maintenance. Regular cleaning and winter protection are crucial for extending their longevity.
Do I need any special tools to install a 120L pond?
You’ll generally need a spade or trowel for levelling the ground, as well as gloves for safety. Some ponds may include installation accessories, so check the product details carefully.
Can I add fish to a 120L pond?
Yes, you can, but it’s essential to choose small fish species suitable for this size of water volume. Overstocking will quickly lead to poor water quality.
What kind of aquatic plants would be best suited for a 120L pond?
Water lilies and marginal reeds are excellent choices, providing habitat for wildlife and helping to naturally filter the water. Consider native species whenever possible.

During autumn, you should remove any susceptible plants and cover the pond with a breathable lid to protect it from frost and debris. Some ponds may require additional winterization steps - follow manufacturer instructions.

Regularly removing fallen leaves and debris, checking water quality (pH levels), and performing partial water changes are key to maintaining a healthy pond environment.
Are these ponds suitable for placing in shaded areas?
While they can tolerate some shade, direct sunlight is beneficial for plant growth. Excessive shade may impact the water temperature and potentially affect aquatic life.
What’s included with a standard 120L pond purchase?
Typically, you'll receive the pond itself, a recessed base, and possibly a small net for debris removal. However, accessories like pumps or filters are usually sold separately.
Can I change the shape of my 120L pond after installation?
Minor adjustments can be made during installation to fit your garden layout, but significant alterations may compromise the pond's stability and structural integrity. Consult with a professional if you require extensive modifications.
