Koi Pond

Adequate oxygen is essential for health and survival of your koi and other pond creatures. As pond life using the oxygen content of water, that needs to be replaced. Oxygen enters the water on the surface of these two contact each other – especially in the koi pond. Therefore, a cascade is a vital complement to their water source.

As water passes over and splashing against the rocks, which contains large amounts of oxygen, water aeration. Aeration way similar can be accomplished with a fountain or a water pump. These methods increase the area of water in contact with air and also prevents the resulting movement koi pond stagnation.

Some symptoms of oxygen:

or Koi fish gasping at the surface for long periods of time.

overnight or death of fish, especially larger and more sensitive.

or turbid water appears black and emits an unpleasant odor.

koi fish or are trying to do or actually jump out of the koi pond.


or oxygen is consumed by large amounts of decomposing waste in
koi pond bottom.

or excessive amounts of algae use oxygen at night
hours with the shortest daylight hours.

or too many fish for the size of the koi pond.

or surface covered with water lilies.


Remove remains or

or slow the growth of algae

decreased number or koi

decreased number or lilies.


Oxygen is also produced by submerged "fuel" aquatic plants and algae. The plants not only help to regulate the levels of oxygen in the koi pond, cooled around too. Plants that normally would not survive in direct sunlight or flourish in desert climate near a waterfall, due to high evaporation rate. Splashes of water and thins as it rolls on the rock, increasing the exposure of the surface. The resulting water evaporation becomes a heat exchanger, cooling the surrounding air by as much as 15 to 20 degrees. Evaporation increases protection moisture for plants from the harsh rays of the sun.

When adding plants to a waterfall, there are many places that can provide plants, such as tears the baby and the different types of moss. Places would not be favorable areas for real water plants may be flat or steep receiving splash, providing moisture to the moss, baby tears (Soleirolia soleirolii) or Isotoma fluviatilis. Other water plants that do not require a specific root base can placed almost anywhere in a cascade of water, such as peas, parrot feathers and watercress.

An attribute of moss or baby tears that do not require extensive amount initially to look great. If you receive the proper amount of moisture, it will spread and grow quickly, even climbing up the rocks and other areas of the lagoon koi.

It is important that the right kind of plant vegetation to avoid overcrowding when ripe. A good example is two common plants in the pond, papyrus and horse tail (Equisetum fluviatale). Both of these plants need to be contained either in a container separate container or bag integrated into the koi pond or waterfall.

Consider creating a bog or marsh pond pot on the perimeter of your koi pond. A swamp is a large pond, shallow (6 to 8 inches deep) pond full of marsh plants. Here is one of the best lists I've encountered to date with more information on the topic: ( rel = "nofollow" href = "http://www.plantideas.com/bog/index.html"> http://www.plantideas.com/bog/index.html) Flood the area with a portion of the water return unfiltered cascade and allow way back in the koi pond. You have now created a very effective natural biological filter. Fish wastes, as it is absorbed by the swamp soil, it decomposes into ammonia by bacteria in aerobic (with oxygen). These aerobic bacteria reproduce at higher rates than do the beneficial bacteria Nitrosomonas, which actually break the ammonia. So aerobic bacteria compete for oxygen with the Nitrosomonas and the use of both the area they inhabit becomes anaerobic or deficient in oxygen.

The ammonia resulting from fish waste is broken down by aerobic bacteria is now "under attack" by Nitrosomonas. This also divides it into toxic nitrites. Then the nitrite is broken down by other aerobic bacteria called Nitrobacters that convert nitrites to nitrates beneficial in the form of food for plants.

Smaller growers can create marsh on the edge of the koi pond in the same way that large marsh pond. When water passes through of these swamps planters and passes through the cleaning process, it picks up oxygen before returning to the lagoon.
