Keeping Residential Pond Ecology Healthier With Water Aeration
Pond ecology is essentially the combination of a small body of water along with the surrounding environment. These two aspects determine what types of fish, birds, and animals thrive in and around the pond, as well as what plant life can be expected. Water quality is inherently important for all these features. Property owners who have a pond on their land and want to maintain its water quality will probably need equipment for pond aeration.
Types of Aeration Devices
Two general types of aeration devices are available from suppliers like Living Water Aeration. One type generates oxygen on top of the water, and the other functions at the bottom of the pond. Fountains keep the water surface moving, while electric and wind-powered devices circulate water from underneath. Larger residential ponds can include the construction of a stream and waterfall, but this tends to be difficult for a smaller pond area since so much extra square footage is needed.
Large vs. Small Bodies of Water
Larger bodies of water in open areas use breezy and windy conditions, as well as rainfall, to keep the surface from stagnating. Even boats moving along the surface, people swimming, beavers traveling, and fish splashing help with this. These activities are not as prevalent with small residential ponds, which usually need some additional help to prevent algae blooms and mosquito infestations.
Negative Effects of Algae and Mosquitoes
Algae create green scum on top of the water. This mat of plant material can grow to be more than two inches thick, making the pond unsightly and unattractive for swimming. The dense plant growth blocks sunlight from reaching far into the water, which also has negative effects on fish, snails, and other aquatic creatures. Algae can even produce toxins that affect the water. In regard to mosquitoes breeding in stagnant water, these insects not only are annoying, they spread serious diseases.
Helping Beneficial Bacteria
Extra oxygen also is conducive to the growth of beneficial bacteria that eat growth that is detrimental to the pond. These may include excessive amounts of nutrients, such as phosphorous. The excess nutrients boost plant growth in the water, which leads to problematic weeds along the bottom and algae scum on top.
