Gallon Per Hour

Pond Shape

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

Self-cleaning design allows water to 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.

Filters

Cost, maintenance, water quality and stability, and capacity are key factors in determining the type of filter to use. The two basic choices are between a pressure filter and a multi-chamber filter. A comparison of head to head for a pond of 3000 gallons reveals significant benefits for multiple camera filter.

Although the equipment costs for multiple chamber filter are a little more ($ 2475 vs $ 2425 for a pressure filter), maintenance, capacity and quality water and stability clearly give the advantage to the multiple camera filter. The electricity costs for multiple chamber filter are about half the maintenance regular or about one quarter, UV costs are about half, and annual maintenance is less. In addition, the filter provides pressurized water quality irregular and stability against multiple filter chamber.

Filter media can be used alone or combined with fine filtration Fine. In general, the media should be used that will maintain the friendly bacteria as bacteria Act in concert with the filter media to maintain a healthy water environment.

Pumps

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

You need a minimum of half the pump capacity in comparison 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 gph to provide more than once every 2 hours. A turnover of 1 1 / 2 hour per hour is preferred.

Pond Aeration

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

The main time is needed ventilation during the summer. The reason is that as temperature increases, water can hold 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 never 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 generally can not be stopped by conventional physical filters, passing through UV light, their internal structures are interrupted. The cells clump together and can be trapped and broken down by the filter. In general, we recommend UV filter 8.10 watts per 1,000 gallons.

Number of fish

Show quality koi need 1,000 to 2,000 gallons per fish; to "regulate fish" koi, 100 gallons per foot of the fish should be adequate.

Installation of pump and filter system

The above components must be balanced and coordinated each other in a well-designed koi ponds. A simple design would make the oval of the pond so that water circulation is easy. Have at least two jets of water from the walls to move water in a gentle circular motion.

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

Barry Graham writes on a variety of topics for the pond industry including koi pond filters and pond maintenance.
