Degraded or Eutrophic ponds and lakes can be characterized by low levels of dissolved oxygen and highly stratified water; where warm, oxygen-rich water is suspended above cool, oxygen-depleted bottom water.
As anaerobic (devoid of oxygen) conditions begin to develop in the deeper water, naturally occurring aerobic microbes can no longer perform beneficial tasks, such as waste digestion or water purification. With time, water quality greatly decreases leading to unsightly blooms of algae, the accumulation of organic sludge and the buildup of gases such as hydrogen sulfide, well known for its offensive odor. Low oxygen levels can also lead to fish kills.
Luckily, degraded ponds and lakes can easily be enhanced with the addition of a Lake Bed Aeration System. Lake Bed Aeration acts to increase dissolved oxygen levels while eliminating water stratification. Aerobic microbes can then recolonize deeper water where they rapidly begin to digest accumulated organic sludge and improve water quality.
how aeration works…
Lake Bed Aeration can be defined as the introduction of compressed air into the bottom of a pond or lake using a self-cleaning, non-clogging Duraplate™ diffuser. When compressed air is released at the bottom it will naturally begin to migrate towards the surface of the water. As it travels up the water column the pressure surrounding the bubbles slowly decreases causing the bubbles to expand in size. Due to the fact that larger bubbles displace more water than smaller bubbles a slight current begins to develop. This current draws oxygen depleted water from the bottom, oxygenates it and transports it to the surface. This action mixes stratified water while increasing dissolved oxygen levels and protecting fish, aquatic organisms and beneficial microbes from suffocation.
