Aeration FAQ's

The Importance of Aeration

Proper aeration is essential to maintaining the health of your pond or lake.

  • Aeration improves water chemistry and clarity
  • Aeration is a leading way to prevent fish kills
  • Aeration helps support fish and microphyle health
  • Aeration can be effective in controlling certain types of weed and algae
  • Fountains typically add 7% value to real estate with water features

Lake Fountain and Aeration Systems

Fountains can be an efficient form of aeration. Another option is the use of an air diffuser system. Although air diffuser systems have lower electrical costs than fountains, they offer little aesthetic value because most of the aeration process takes place under the water. 

Question: What is the difference between a display fountain and an aerating fountain?

Answer:  “Display fountains generally have one use, and that’s for looks. Generally, these patterns are multi-tiered or they have very tall or wide patterns. Aerating fountains have dual purpose: they want to aerate, but you also have a nice pattern for looks. These patterns are generally limited to cone shaped patterns.”

Question: How does clarity affect a pond or lake?

Answer: “Sometimes when clarity is the objective, we first identify the cause: algae, inert, organic material. Several techniques are used to remove these causes, thus creating clarity. The benefits are aesthetics. The cause could be the source of a bigger problem, or it could be from a discharge requirement. When the lack of clarity is the goal, it’s for weed control measurement or enhancement of the fish population. We can use pond dyes to artificially block sunlight, thus limiting weed growth; we can also use pond fertilizers to produce algae blooms that serve as food source for bream fry,  which improves recovery rate.”

The Trouble with Weeds

Excessive plant growth can result in cloudy water and even a foul odor. Reducing the amount of algae and, thus, the amount of excess plants can be achieved by introducing various fish, herbicides or even aeration solutions into the pond.

Natural Treatment Options

Certain types of fish, including some types of carp and Tilapia, can decrease the amount of algae in a pond or lake, as algae is a primary component of their diets. 

Stagnation can also result in algae-filled water. Providing aeration through a fountain or underwater diffuser system can disrupt the peaceful water in which algae thrives.

Question: What is an aerator?

Answer: "An aerator is generally a mechanical device used to move water that will improve dissolved oxygen levels. Common aerators or air diffuser systems, paddlewheel systems, or pump systems are running off of electricity, solar power or even wind-driven devices."
