How to Install a Pond Aerator


A pond aerator increases the amount of oxygen to fish and plants in the underwater environment. The size of the aerator is dictated by the size of the pond and depth of the water. There are two distinct types of aerators: one that simply moves the water from a certain level to the surface, and one that actually pumps air into the lower areas of the pond. Consult your local agricultural extension service for their recommendations.

Step 1

Lay out the pond aerator system to ensure you have all the parts provided by the manufacturer, including the water or air pump, electrical connection hardware, hose connections, hoses and the discharge units that will be placed on the bottom of the pond.

Step 2

Install the hoses onto the pump mechanism. This may entail making mechanical connections of certain lengths for placement of the discharge units in the pond.

Step 3

Load the discharge units into a small boat then motor out into the pond. Drop or set the discharge units throughout the pond, allowing them to float to the bottom.

Step 4

Connect the pump to your electrical supply. Turn the pump on to test the location of the discharge units. Move the hoses or units as needed for the maximum effect to the pond.

Step 5

Place the pump unit inside the metal enclosure to protect the mechanism from animals and inclement weather.
