koi pond cleaning

Pond shape

The sides of the pond should be 90 degrees, going down, to reduce access by predators. The fund must be 4 '- 10 'depth and the recommended size is a minimum of 1000 gallons, bigger is better.

self-cleaning design allows water flow in one direction around the pond in the shape of the walls and the direction of the jet of water. Other designs require multiple jets.


Cost, maintenance, water quality and stability, and capacity are key factors to determine the type of filter to use. The two basic choices are between a pressure filter and a multi-chamber filter. A comparison head to head for a pond of 3,000 gallons revealed significant advantages for a multi-chamber filter.

Although the costs of equipment for multi-camera filters are a bit more ($ 2,475 vs. $ 2,425 for a pressure filter), maintenance, capacity and water quality and stability clearly give the advantage to multi-chamber filter. electrical costs for multi-camera filters are about half, regular maintenance is approximately one quarter, UV costs are about half, and annual maintenance is less. In addition, the pressure filter provides irregular water quality and stability to multi-chamber filter.

filter media can be used alone or combined with fine and finer filtration. In general, media media should be used to maintain friendly bacteria as bacteria act in concert with the filter media to maintain a healthy water environment.


To calculate the required pump size for your pond, you need to determine the gallons of water in the pond. You can calculate liters of water in the pond by multiplying the average width of the average length of the average depth to get cubic feet. Multiply by 7.481 cubic feet to get the number of gallons in the pond.

A minimum average pump capacity as compared with the size of the pond. For example, if the pond has 5,000 gallons, you need a pump and filter with a capacity of 2,500 gallons per hour to provide more than once every two hours. Turnover of 1 1 / 2 hour by hour is preferred.

Pond Aeration

Aeration means adding air to water to increase oxygen levels in water an air pump is the standard method of aerating the water. The beneficial bacteria that keep the water healthy need oxygen to thrive. In general, you need air 40lpm per 1000 gallons of water.

The primary aeration time is needed during the summer. The reason is that as the temperature rises, the water may contain less oxygen. In addition, respiration rates of plants and animals increase during the summer, also increases the need for aeration.

One caveat: The air pump should not be installed below water level unless there is a check valve on the line. Otherwise, you end up with serious maintenance problems.

UV Filters

UV filters are used to kill algae, and some disease-causing bacteria or viruses. algal cells usually can not be stopped by conventional filters physics, by going through the UV light, their internal structures interrupted. The cells can then be grouped and being caught and disaggregated by the filter. Usually 8 to 10 watts of UV per 1,000 gallons is recommended.

Number of fish

Koi Show the quality of fish need from 1000 to 2000 gallons per fish because "regular koi fish, 100 gallons per foot of fish should be adequate.

The installation of the pump and filtration system

The above components need to be balanced and coordinated with each other in a pond design good koi. A simple design would make the oval pond so that water flow is easy. Have at least two jets of water from the walls to move the water with a gentle, circular.

For an even simpler design, the water pump on the pond and have it fall back into the pond in a cascade. The bio-filter (s) and the pump would be placed in the top of the waterfall. The cascade act as an aerator for water. This design also facilitate access to the pump and filters for regular maintenance.
