Robust-Air Diffuser

The Robust-Air is a low pressure diffuser. Ideal for ponds with one or two deep spots. Allows you to aerate a fairly circular area. It is most effective when covering a small area and becomes less effective as the area gets larger.

Here are the advantages seen when using bottom aeration:

• Circulation of the entire water column in relation to the depth of the diffuser and the volume of air injected;
• Elimination of thermal stratification (generally prohibited in the case of natural trout lakes);
• Increase in dissolved oxygen levels, which stimulates the natural aerobic digestion process, thus reducing the thickness of organic silt and the accumulation of sediment;
• Prevents fish kills during winter by increasing the oxygen available in their habitat;
• Reduces mosquito populations;
• Eliminates foul odors from unwanted gases;
• Reduces organic bottom sediments by avoiding sediment anoxia;
• Sequestration of phosphorus in sediments;
• Preservation of a healthy aquatic ecosystem.
