Relax and reflect with a soothing and stylish statement water feature that’s good for the local ecology too
Having a fishpond may not be everyone’s idea of fun, but those who love them know that this humble water feature has the power to create tranquillity in the most urban of locations. From the soothing sounds of rippling water to the calming nature of fish swimming in and out of reeds, a fishpond could bring the quiet moment of contemplation your garden is missing.
1. Installation
You can buy pre-made pond kits from hardware stores and landscaping retailers, however these are usually best suited to small projects. If you plan to install a large pond, you’ll need to consult a professional to ensure the landscaping and lining are done correctly.
Concrete is robust; rubber and plastic can also be used, though require careful installation to ensure the pond is water-tight. “If you’re doing a natural-style pond, a durable, UV-stable PVC pond liner is best,” says garden designer James Headland. “Just make sure it’s also fish- and marine-safe.”
2. Fish
Not all fish species will thrive in a pond, so be sure to consult an aquatic expert before purchasing. “Goldfish are the most popular fish kept in ponds,” says James. “There are heaps of different species, colours and fin shapes to choose from.”
Remember, fish require food and oxygenated water to survive, so choose pond-happy plants that will supply food for the fish, and a water pump that properly oxygenates
the water.
3. Plants
When it comes to landscaping your water feature, rocks, pebbles and pavers are excellent for framing, but you’ll need a specific selection of plants to ensure a successful ecosystem within: oxygenators, floaters, submersibles and marginal plants. Some pond-loving species include water lilies (Nymphaea spp), cardinal flowers (Lobelia cardinalis) and blue flag iris (Iris versicolor). Ask a specialist at your local plant store for recommendations that suit your climate.
4. Location & depth
When choosing a location for your fishpond, be sure to avoid areas that are vulnerable to gusty winds and lots of falling leaves, or where water pools after heavy rain. A sunny location that’s protected from some of the harsher elements and is partially shaded is perfect for both fish and pond plants.
“Somewhere with a little cover from foliage around the pond, and planting within the pond to protect fish from predators is best,” says James.
Before constructing any pond, big or small, it pays to check with your local council. Of course, shallow ponds are good for growing lily pads and, if less than 400mm deep, do not require fencing. They also take up less space and are cheaper to install, but are only suitable for small fish.
5. Water pumps & filters
To maintain effective filtration and, therefore, water quality and clarity, you will need to install a pond pump. “Low voltage is best, and try to match the size of the pond with the size of your pump so it works effectively to move water around,” says James.
Look for a pump that can process your pond’s entire water volume within two hours, or faster if the pond also has fish. A submersible pump is the easiest to install as it’s simply placed in the pond, while external pumps require plumbing through the wall of the pond, which requires extra water sealing.
Solar-powered pumps are best, but if you require an electric connection, ensure it’s installed by a professional – never use extension cables. Consult an aquatic gardening expert if you have any more questions about filtration.
One fish, two fish, which fish?
As mentioned goldfish are best suited to ponds. There are many types you can consider from the standard, common-or-garden comet goldfish and shubunkins through to the more exotic fantail, lionhead and red cap oranda goldfish.
It’s best to keep the more common types with the more common types as they’re generally the most boisterous, and keep only the fancier, more gentle ones together to avoid conflict. Remember koi carp, while very pretty and a popular choice for ponds in Asia, are classified as a noxious fish in New Zealand, growing up to 75cm and weighing up to a 10kg. It’s illegal to have them in your pond.
