Pond aerators are essential for fish and aquatic plants to thrive. A quality aeration system keeps decayed matter and mosquito infestation in your pond. Water in the pond requires appropriate oxygen introduced by water circulation or the introduction of new water. The content of oxygen in the pond water should be between 7 to 14 mg/liter of water. Excess oxygen returns to the atmosphere since it can’t be used in the pond.

Promoting appropriate oxygen in pond water involve circulating water with a higher temperature to areas with lower temperature. This continuous circulation is essential to enhance oxygen concentration through the pond. The recommended oxygen concentration when water is at 15 degrees Celsius is 17 milligrams per liter.

Stagnant water usually has a dust or pollen film that inhibits direct entry of oxygen into the water. However, this film is denser than carbon dioxide coming from the water bottom from decaying plants and rotting aquatic animals. Accumulation of this gas limits direct entry of oxygen into the pond water. Encouraging water circulation by an aerating system encourages passage of oxygen into the lower layers of the pond

Obtaining high pond aeration coefficient

Promoting good air transfer in the pond water requires investing in the best pond fountain aerator. This encourages air bubbles in the water to spread throughout in the best way possible. Continuous circulation of water by an aerator encourages the dissolution of oxygen. It ensures that the air bubbles become smaller in the best way possible to ensure it’s accessed by fish and aquatic life.

Types of pond aeration systems

Mechanical aerators

These promote water oxygenation by use of a motor to make turning paddles. The water surface moves to produce splashes to meet the atmosphere covered by a fine layer of air. Afterward, the splashes fall into the pond introducing oxygenated air into the pond. Mechanical aeration systems are used in water purification plants for water recycling for aerating superficial layers.

Floating fountains

Apart from promoting a pleasing aesthetic effect, floating fountains encourage aeration in a pond. Jets are produced that break up into tiny water spheres. These make contact with the atmosphere and return with a film of air. Afterward, the jets fall back into the pond transferring oxygen throughout the pond. As the splashes fall back into the water, wave motion is created on the surface breaking the superficial film formed by pollen and dust.

Submerged aerators

These introduce more oxygen into the water for each kilowatt to promote optimized aeration. A submerged aeration system works according to the Venturi effect. It creates a depression to suck air into the Venturi chamber through a tube connecting to the atmosphere. After mixing, air and go to the pond surface to encourage aeration.

Bottom line

Aeration is essential for pond health and survival of fish or aquatic life. An appropriate aeration system is required to encourage oxygen flow throughout the pond. This enables aquatic life and koi fish to thrive. It also limits the presence of decayed matter that might encourage noxious odors in your pond. With the range of aerators available, purchasing the right aeration system will ensure that your pond is healthy always.
