A koi pond is a type of ornamental pond typically used to house koi, which are a type of domesticated carp. Koi ponds usually have a layer of gravel at the bottom, which serves a few purposes.
The gravel provides a place for the koi to dig and forage, it helps to anchor plants, and it also provides a surface for beneficial bacteria to grow.
What should I put in the bottom of my koi pond?
The bottom of a koi pond should be filled with a layer of gravel and then covered with a layer of plastic to keep the pond clean. The koi will eat the algae and bacteria that grow on the gravel and plastic, and the pond will be healthier as a result.
Should you put anything in the bottom of a pond?
It depends on the specific pond and its specific needs. In general, however, many pond owners choose to add artificial or natural debris to the bottom of their ponds to help with stability and to provide nutrients and minerals that can be beneficial to fish and other aquatic creatures.
Do you put stones on the bottom of the pond?
There is some debate over whether or not stones should be put on the bottom of a pond to help with the circulation of the water. Some believe that the stones can help to keep the water cleaner and move more quickly through the pond, while others believe that the stones can cause damage to the pond’s ecosystem.
Ultimately, it is up to the pond owner to decide whether or not to add stones to the bottom of their pond.
Do you need gravel in a koi pond?
Gravel is commonly used in koi ponds as a substrate for hiding plants or to provide a location for spawning. Gravel is also beneficial to the koi as a food source.
Koi will eat the gravel and use it as a source of calcium and other minerals.
How do you keep the bottom of a koi pond clean?
Koi ponds can become clogged with leaves, twigs, and other debris that can easily get sucked in by the fish. To keep the bottom of the pond clean, you can use a rake to remove the debris, or you can use a water jet to blast it away.

Can you put sand in the bottom of a koi pond?
There are a few things to consider before filling a koi pond with sand. The pond should have a diameter of at least 12 inches and the sand should be of the same size as the koi.
The sand should also be free of pollutants and have a pH level of 6.5 to 7.5. Finally, the sand should be screened so that small rocks and debris are removed.
Should koi ponds have rocks?
The decision of whether or not to add rocks to a koi pond will vary depending on the specific circumstances and preferences of the owner. However, some factors to consider when making this decision include the size and shape of the rocks, their effect on the water quality, and the available space in the koi pond.
Adding rocks to a koi pond can have a number of benefits, including improving the aesthetics of the pond, increasing the fish population, and improving the circulation of the water. When selecting rocks, it is important to consider their size and shape, as well as their effect on the water quality.
Generally, small, round rocks are less likely to cause problems with the water quality, while larger, more angular rocks can cause damage to the pond’s sedimentation and filtration systems.
Another factor to consider when adding rocks to a koi pond is the available space. If the rocks are too large or there isn’t enough room to fit them in the pond, they may need to be removed or relocated.
Does a koi pond need a bottom drain?
Yes, a bottom drain is necessary for koi ponds. The reason is that when koi ponds are full of water, the water will flow out the bottom of the pond and away from the fish.
A bottom drain will help to keep the water in the pond and keep the fish safe.
Does a koi pond need a liner?
A koi pond does not need a liner, but koi do require a good biological filter to keep them healthy. A liner would only add to the cost of maintaining a koi pond and may not be necessary if the pond is well-maintained.
Can I put pea gravel in my pond?
Most likely not. The potential for harm from adding gravel to a pond is significant.
Gravel can create serious blockages in the pond’s filter system, which can lead to fish deaths and serious water quality problems. Additionally, gravel can accumulate over time, creating a potential hazard for children and pets who might play in the pond.
Do Koi like rocks?
It depends on the individual koi’s personality and preferences. Some koi may love rocks, whereas others may shy away from them.
Some koi may even become aggressive when approached by rocks, so it is important to test out different rocks to see what ones your koi prefers.
Summary
A koi pond typically has a layer of gravel on the bottom, which can be anywhere from 1-2 feet deep. The gravel provides a place for the koi to dig and helps to keep the water clean.
