What is the difference between an aerator and fountain?

An aerator adds oxygen and induces circulation into the pond or lake for water quality management purposes; while a fountain is designed to throw water into the air to create an attractive pattern. In other words, aerators pump high volumes of water at low pressure, while fountains pump low volumes of water at low pressure. (Imagine a garden hose with the water on and nothing attached to the end (high volume, low pressure), now place your thumb over the end, (low volume, high pressure.)

Want the look of a fountain, but the benefits of an aerator? Look at our Aerating Fountain line for your options. 

What is pond aeration?

Pond aeration is the introduction, circulation and mixing of oxygen into the water column. Pond aerators are able to de-stratify the pond layers and increase oxygen levels in the water column. Oxygen promotes aerobic (active) consumption of excess nutrients that can cause excessive algae, odors, and potentially lead to fish kills.

Otterbine systems are proven to offer the highest oxygen transfer and pumping rates in the industry, want to see the science? Check our our Performance Results!

How often do I need to run my aerator?

It is recommended that the aerator is run 24/7 for optimal aeration benefits. If you need to restrict running time, be to run the aerator run at night during the dark phase of photosynthesis, this is when aquatic vegetation reproduces the most.

Recommended Hours of Operation

  • Aesthetic Purposes: Customer Preference
  • Average Lake Management: 12-16hrs/day
  • Severe Lake Management: 24hrs/day

What size aerator/fountain system do I need?

If you are looking for aeration or water quality management benefits, Otterbine recommends 1.5HP to 2HP per surface acre. For severe aquatic management needs consider sizing up to 2HP-3HP per surface acre.
