Koi Pond – 5 Things You Need to Know Before Building your Backyard Water Garden Pond


Koi Pond Location:

When building a Koi Pond from scratch, look at the area that will surround the Koi or Gold Fish Pond. Torrential rains may cause the Koi Pond to overflow. Be cognizant of drainage and the fact that surrounding areas that may become saturated; affecting the integrity of the water garden pond structure, particularly if pond walls are over 4’ high and the water flows backwards. Plan ahead by overfilling the pond and see where the water flows. Add drainage pipes as necessary in the neighboring ground to divert overflow water away from the base of the pond. Build up the ground and add plantings at the base to improve stability.

Pay attention to what is above the Koi Pond as well. Spring blossoms and leaves falling in the autumn may create extra requirements for pond maintenance if the pond filter becomes cluttered with natural debris and backs up. Without maintenance, the pump will seize, so eliminate unnecessary debris from entering your ponds surface by positioning the Koi Pond or Water Garden Sanctuary in an area that gets sunlight and is not directly beneath trees shedding leaves and needles.

Water Garden Plants in your Koi Pond:

Including plant life adds value, health and natural visual appeal to any Water Garden Sanctuary. There are many different varieties of Koi pond plants; and they thrive at different depths so be sure to add different levels of height to the base of your water pond. In addition to the Water Garden plants giving Koi fish protection from predators, they also provide shade and keep bacteria growth at bay.

Many pond plants can be removed at the end of the season, and stored much like root vegetables are stored, in a cool dry place for the winter. In Spring, induct them back into the Koi pond. They will bring delight season after season.

Filters for a Koi or Goldfish Pond:

Koi ponds do require aeration which typically means buying a submersible pump but it doesn’t necessarily mean you need to have a filter. If there are few fish, the pond is small, there is a waterfall, a bog area, and healthy plants, the natural state of the pond will balance itself out and you won’t need a filter.

Filters can be obtained to protect not only the mechanical workings of the pump, but they can also protect the biologic makeup of your pond, removing harmful bacteria that can affect the health of the fish.

Consult manufacturer’s instructions on the filter to ensure that is the appropriate size for the Koi Pond. Ideally, find the volume of the pond before leaving the house to buy a filter by roughly measuring the pond’s surface diameter and multiply it by its depth. This will give you about an 80% accuracy which should be sufficient in selecting a filter. Look for a filter that will push the water through the filter system between once and twice an hour. Any more will be wasting electricity, and any less can potentially harm the health of the Gold fish or Koi.

Cleaning your Koi pond:

Don’t do it. It takes a while for the pond to naturally build up a balance. Most algae at the bottom of the pool-liner and on the rocks are a good thing. Harmful bacteria cannot be seen. Waterfalls, bog areas, and plants will help regulate bacteria, and as long as the filter is maintained, taking care to clean it in pond water periodically when the flow becomes blocked, the pond should take care of itself.

Koi Pond Predators:

Along with other of nature’s creatures that may enjoy the backyard water garden sanctuary such as frogs, birds, and snakes, the Koi Pond may attract raccoons or flying birds such as the Blue Heron. Fastening chicken wire over the pond temporarily during the birds’ migration season can prevent attacks. Other options are sensor driven water sprinklers or noisemakers. Alternatively, letting mother nature take its course, and instead concentrating on building a Koi pond that spawns new fish year after year, provides a birds’- eye-view of nature at its finest.
