No doubt we?EUR??,,????'???ve all had our bouts with algae. Although it?EUR??,,????'???s an important part of the food chain for aquatic life, too much is unsightly, will cause foul odors and discolor the water. When algae gets to be excessive, chances are the source of the problem is high nutrient run-off.
Unfortunately, one of the biggest contributors to run-off is something needed to keep turf lush and abundant. That?EUR??,,????'???s right, fertilizer.
Put more scientifically, ponds have their own bacteria that decompose nutrients and act as clean-up devices. Two types of bacteria are present in all lakes and ponds: aerobic and anaerobic. In a healthy pond, there are more aerobic bacteria, which break down the nutrient load by feeding on the organic nutrients and then converting them into non-organic compounds that algae cannot readily use for food. Like almost all living organisms, these bacteria require oxygen to complete the process.
In the common instance that too much fertilizer is being induced into a watershed, the aerobic bacteria cannot consume the nutrients fast enough and the pond enters a eutrophic stage. In this state, aerobic bacteria are unable to operate efficiently, and anaerobic bacteria take over. Anaerobic bacteria (which can live and grow without the presence of oxygen) decompose nutrients too?EUR??,,????'??+but at a much slower rate. When the anaerobic process occurs noxious by-products, such as methane, ammonia and hydrogen sulfide, are emitted.
What?EUR??,,????'???s worse? Well, if your pond has a high nutrient load from fertilizer and it is used it as an irrigation source, the turf can become seriously damaged. At this point, additional nutrients are being added on top of what has already been applied. These nutrients in excess are harmful. Too much phosphorus may limit the ability of turf to consume other needed nutrients. Too much nitrogen is equally as damaging as it can restrict root systems, reduce the turf?EUR??,,????'???s tolerance to normal wear, and make the turf vulnerable to disease and pest attacks. In other words, it all adds up to more maintenance and money on your part!
The solution is oxygen. Aerators encourage the longevity of aerobic bacteria by constantly inducing oxygen into the water. Since aerobic bacteria need an abundance of oxygen to consume excess nutrients in the water, aerators help by constantly replenishing their O2 supply. This in turn keeps your water clear, odor-free and pure enough to use for irrigating.
During the warm months, nothing can be worse than having to swat away insects while trying to enjoy the beauty of the outdoors. While insects alone are irritating enough, now with the threat of West Nile Virus from mosquitoes, these little pests are not just bothersome, but dangerous.
Water is a great attraction to most insects, mosquitoes in particular need water to thrive as they breed in stagnant water where there are aquatic weeds and scum to which they attach their eggs. Chances are one does not want to get rid of a water feature in order to get rid of the bugs though. So, what to do?
While one may turn to insecticides to solve the problem, they are costly, can be harmful to the environment and contribute to polluted run-off. Instead, installing an aerating fountain is a better solution.
?EUR??,,????'??Stagnant water is the primary breeding ground for mosquitoes and various types of insects. Aerating fountains break up stagnant water conditions by pumping and circulating water in areas that would normally be still, thus inhibiting the insects?EUR??,,????'??? ability to properly nest and lay eggs or reproduce,?EUR??,,????'?? explained Charlie Barebo of fountain manufacturer Otterbine Barebo, Inc.
In the chance that any eggs were already laid, by breaking up the surface water and constantly causing surface movement, aerators prevent any eggs or larvae from completing their life cycle.
Someone clever person once remarked that ?EUR??,,????'??every problem has a solution.?EUR??,,????'?? You may have always been under the impression that the only solution to your biggest pest peeves, algae, geese and insects, were harmful pesticides, insecticides, and costly alternatives such as dredging your pond.
