The use of an aeration system in a pond or lake will increase the oxygen concentration, create water movement, increase both fish productivity and pond health, as well as deter unwanted vegetation growth. There are many types of aerators on the market, with these being broken into two categories: surface aerators/fountains and bottom-based diffused aeration systems. Bottom-based diffused aerators, such as our CPA-I,II,III, and IV systems, do not give the impressive display that a fountain will, but will destratify the water, providing more uniform oxygen levels throughout the entire pond. This low profile aerator prevents summer turnovers and winter kills, and increases the usable area in the pond. A bottom-based diffused aeration system works by pushing air down to the bottom of your pond. The air is then diffused into tiny bubbles that float to the surface, breaking the thermocline. This process destratifies your water, dispersing life-giving oxygen throughout. Due to the lack of oxygen in the summer months, fish generally cannot survive in the lower half of your pond for long periods of time. Adding oxygen will allow your fish to make use of both the upper and lower lake strata. In addition to providing life-giving oxygen, this system helps reduce organic material on the pond bottom. Additionally, a diffused aeration system vents toxic gases such as ammonia, carbon dioxide, and hydrogen sulfide from the pond into the atmosphere. Algae and weeds thrive in a carbon dioxide rich environment. By reducing gasses, such as carbon dioxide, you will reduce or eliminate your nuisance algae and weed problems. The situations and considerations are virtually endless, so take some time when researching the best method of aeration for your particular application. Depth, pond size, and shape are important parameters when choosing the proper type of aeration system.
