The pump distributes the water to the filter and water sports (waterfalls, fountain, jet rain or bell). It brews the water and allows its oxygenation.

Determine the pump flow required

The water of 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 pump dedicated to fountains or to streams, the power is determined by the rise height of the water and the desired discharge rate (1.5 L of water / min per cm of waterfall).

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 basin in the raised to avoid rising mud.

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.
