Fine Bubble Aeration

Fine bubble aeration (commonly referred to as diffused aeration) is the process of introducing oxygen to a body of water through the application of tiny bubbles at the base of a pond or lake.

Recommended for lakes and ponds over two metres deep (otherwise, we suggest a Surface Aerator), diffused aeration uses a submerged system that promotes the vertical movement of ultrafine bubbles as a means of combating lake stratification through ‘air-lift’.

What is Stratification?

Stagnant lakes or ponds that rely only on surface wind aeration commonly suffer from a scenario called 'Stratification'. Stratification is the formation of distinct thermal layers produced when the sun can only penetrate to a certain depth. This causes colder layers of water to develop beyond what's called the 'Epilimnion' (the upper-most layer of a stratified lake).

Stratification is a problem because ultimately it depletes the water of oxygen, promotes anaerobic activity, stimulates algal growth and causes an ecosystem imbalance. For water managed as an amenity, such as a fishery or boating lake, the implications can not just render the water inaccessible but the resulting algal blooms and released gases can be harmful to people and animals.
