What does an aerator in a pond do?

The main purpose of aeration is to increase and stabilize the amount of dissolved oxygen in the entire water column and this has a widespread effect on many different aspects of pond and lake health. Aeration can also reduce the amount of pond algae through a variety of processes.

Do you need an aerator in a pond?

You don’t “need” to aerate your pond. BUT, a properly designed and installed aeration system will greatly slow down the eutrophication process, help prevent summer and winter fish kills and prolong the life of your pond. There are basically two types of aeration: surface aeration and bottom diffusion aeration.

What size aerator do I need for my pond?

For normal water conditions use a minimum of 1-1/2 HP (one and one half HP) aerator per surface acre. For warmer climates or excessive algae growth use a minimum of one 2 hp aerator per surface acre. CALCULATE NUMBER OF AERATORS Number of aerators = Number of acres (rounded upward) Example: The lake is 220ft.

Does aeration heat up water of pond?

On hot days, with a bottom mounted aeration system operating, the cool waters are brought to the surface where heat transfer from the warm atmosphere increases water temperature . As the circulation continues warmer waters replace cooler waters at the bottom of the pond.

What does a pond aerator do?

A pond aerator is useful for many things. Perhaps the most important is that it allows for increasing the oxygen levels in the water. The aerator also helps to mix the oxygenated water from the top of the surface with the water at the bottom of the pond. This spreads oxygen but also keeps the water at the perfect hot/cold temperature for the fish.

What does an aeration of water produce?

Aeration, properly applied, will meet the BOD of the water body, and produce positive dissolved oxygen (DO) levels and homogenous temperature throughout the water column. Benefits of sub-surface aeration: Moving water from the lowest levels of the pond, lake, or wastewater lagoon, to the surface, is an important job of aeration.

How does pond aeration work?

Pond Aerator FAQ’s. How does a pond aerator work? The two most common types of pond aerators, surface and submerged, supply oxygen to the water in different ways. A surface aerator takes water from your pond and throws it in the air, where it picks up oxygen and falls back into the pond.
