Diffused fishery aeration systems—also known as air diffuser aeration systems—delivers fine bubbles from the pond or lake bed to circulate water, raise dissolved oxygen (DO), and stabilise water quality across the whole fishery. It’s quiet, energy-efficient, and ideal for maintaining fish welfare year-round without visual surface disturbance.
A shore-mounted compressor sends air through weighted hose to bottom-placed membrane diffusers. Thousands of micro-bubbles rise, dragging low-oxygen bottom water to the surface where it re-oxygenates, while mixing the entire water column. The result is even DO levels, reduced thermal stratification, and a more resilient aquatic environment—day and night, in all seasons.
Thermal stratification occurs during the summer, this is when layering within the water occurs. The surface layer will contain warmer, oxygen-rich water, whilst the bottom layer contains cooler oxygen-depleted water. The Thermocline separates these two layers. It is the difference in water density that stops the top and bottom layers from mixing.
By aerating and circulating water from the fishery bed, any toxic gases that had been previously trapped under the thermocline layer are released providing a balanced habitat. This creates aerobic conditions near the fishery bed, where microbial processes can naturally break down nutrients that would otherwise be used in the production of noxious aquatic weeds and algae.
Q: Will diffusers bother anglers or fish?
A: No surface clutter, and operation is very quiet. Fish generally benefit from the stable oxygen profile and use more of the lake.
Q: Can I run them on a timer?
A: Yes, but we recommend continuous operation in warm months to maintain stable DO and mixing. Timers are useful shoulder-season.
Q: Do diffusers work in shallow ponds?
A: Yes—coverage per head is smaller, but strategic placement still delivers excellent results. For very shallow areas, we may combine with a surface aerator.
Q: What about power at remote sites?
A: Solar or hybrid systems are available, sized to your runtime and seasonal demand.
