Why is important pond and lake earation?

Aeration is the transfer of oxygen from air into water. All healthy bodies of water need oxygen for the normal biological cycle. In large bodies of water, this occurs naturally as a result of wave action. In smaller lakes and ponds, it is easy for biological factors to become unbalanced, causing the oxygen levels to drop, making it necessary for mechanical aeration. Insufficient aeration and low oxygen levels can cause fish kills, unpleasant smells and unsightly water.

Without sufficient circulation, a pond becomes stratified with warmer water on the surface and colder, oxygen-depleted water on the bottom. Lack of oxygen increases the anaerobic (without oxygen) decomposition of the sludge at the bottom. That increases nutrients in the pond, which, in turn, increases algae blooms. An uncirculated or non aerated pond or lake develops a thermocline. This is a stratification of the water by temperature.Read more

The warmer water is at the surface in contact with the air and the cooler water drops to the bottom where it becomes oxygen starved. Proper circulation and aeration will increase the amount of oxygen at all depths, and break down the thermocline. Aerating a pond provides a healthier habitat for fish, reduces algae blooms, improves water clarity and rids the pond of bad smells. Aeration also improves the effectiveness of bacterial products that reduce nutrients and improve water clarity. ACI offers three types of mechanical means to add oxygen to a lake or pond: Surface Aerators, Lake Bed Aerators. and Pond Bottom Circulators.

Definition of a Floating Display Aerator

There has been much confusion in the industry regarding the definition of an aerator. The Aqua Control definition is very specific: only high pumping rate, axial (propeller) pumps are called Aerators because good aeration can only be achieved by high pumping rates. Our Display Aerators pump high flow rates relative to the horsepower while creating very attractive patterns that have a high aeration efficiency.
Fountains, on the other hand, are created with centrifugal pumps which produce higher patterns, but with much lower flow rates. ACI feels that these pumps should not be called Aerators or even Aerating Fountains even though their splash does create some aeration.

Titan Fountains

Titan Fountains have the motor and pump mounted horizontally. Advantages include a simple installation that requires little or no adjustment. The water fountain can be operated in as little as 37 inches (1,3 meters) of water and can be lit with up to 20 submersible lights and a choice of up to six colors. The suction screen is cleaned from a boat and is easily removed without tools for complete cleaning.
