Why Aeration

Aeration is crucial for your water catchment to survive. Aeration is the process of the deep water mixing with the surface water through the interaction of temperatures. The surface water is well-oxygenated whilst the deep water is not, so circulating the two means that the deeper waters will increase in oxygen levels, lower nutrient levels and above all, continue to sustain life. For most bodies of water this happens naturally several times throughout the year.


For water bodies being used for more agricultural purposes, there is a much higher demand for oxygen and nutrients due to the higher density of aquatic life. The natural cycle is simply not enough to support life in the long run and eventually your fish will die and sludge and algae will build up leaving you with a pungent smell. However, there is a solution.


Utilising aerating equipment in your water catchment will not only mimic the natural cycle, but increase the number of cycles from a few a year to several a day! It works by simply supplying air pumped from above group to a diffuser settled at the bottom, which will break up the air into tiny bubbles that rise to the surface. This will push water upwards from below and create a circulation effect. The artificial circulation has numerous benefits, such as;

  • keeps dissolved oxygen levels nice and high,
  • stabilises temperatures,
  • prevents stratification,
  • manage nutrient levels
  • offsets BOD (Biochemical oxygen demand)
  • aerobic bacteria (digests sludge) replace anaerobic bacteria (produces harmful gases)


To continue to sustain healthy aquatic life and the water quality of your pond, dam or lake itself, there needs to be enough oxygen. With an aeration system, the catchment itself is working at maximum efficiency to supply your species with the best environment possible.
