The pump and filter are essential for the maintenance of a garden pond. They oxygenate the water, remove impurities and parasitic algae. Our zoom to choose the pump and the filter of a garden pond ...
Our advice to choose, install a pump and a garden pond filter to ensure that it has water with perfect balance.
1.The garden pond pump
The pump distributes water to the filter and water games ( waterfalls, fountain, rain shower or bell). It brews the water and allows its oxygenation.
Determine the pump flow required
The water in a garden pond is renewed every two hours. The flow rate of the pump in liters/hour must be equal to half the volume. For a solar pond pump dedicated to fountains or streams, the power is determined by the height of upwelling and the desired discharge rate (1.5 L of water/min per cm of the cascade).
Installation of the pump in the garden pond
Install the pump in a basket with pierced edges. Garnish with volcanic rocks or pozzolana for pre-filtering. Connect the pump through the ducts to the filter and the water features. Place the basket at the bottom of the pool in the raised to avoid rising mud.
2. The garden pond filter
The filter cleans the water of suspended waste and algae. This filtration is essential for any pool exposed to the sun, falling leaves or an area greater than 20m2.
The different types of filter
The underpressure filter is suitable for small and medium volume garden ponds. It connects to a pump. It is placed inside or on the edge of the garden pond.
The gravity filter is placed at the highest point of the water circuit, next to a stream feed for example. Water flows through the filter by gravity flowing to the pond. This type of filter is suitable for large pools.
Mechanical filtration
Mechanical filtration traps impurities in grids, foams, Japanese carpet ... It is effective for solid waste.
Biological filtration
Perfect for eliminating microscopic parasites, the biological filter houses purifying bacteria in nesting mosses. The biological filter must operate continuously to ensure the survival of the bacteria.
Filter maintenance
Preferably place the filter out of the garden pond for easy maintenance. Do not clean it with tap water at the risk of killing the purifying bacteria. Some are also developing on the foams of mechanical filters. Inspect the filters regularly and change them at least once a year.
The manufacturers offer complete kits including the pump, the filter and the materials necessary for their installation and maintenance.
