What is that bad smell? Could it be rotting vegetation from the bottom of your pond? If only you knew what pond aerators were used for before building the pond and stocking it. It is a matter of simple science, really. It is not effective enough to aerate water at the top; it needs to happen from the bottom up. And thats where pond aerators come in handy.
Aeration means adding air to the water. Air is made up of 22% oxygen so adding air, adds oxygen, and we all know that oxygen is vital for all life forms. It is no different at the bottom of your pond. Whatever aquatic life is lurking there, plants or fish, there needs to be a regular, fresh intake of air to breathe oxygen back into the system. Pond aerators do that job for you and do it very well.
Splashers vs. Aerators
In days gone by, pond aeration has been done in a variety of ways. Most of these methods have been by surface splashers; electric pumps, propellers or fountains. All of these have had their disadvantages, particularly that they mostly work with efficiency in shallow water environments. Pond aerators work way below the surface, whereas surface splashers only expose to the atmosphere, the water on the surface.
The lovely thing about the job that pond aerators do, is that snails and insect larvae can make their homes at the bottom of the pond because they will obtain the oxygen they need to survive. This, in turn, provides food for the fish swimming around and looking for sustenance.
Pond Circulation Needs
Furthermore, if there is any pollution in the pond from whatever source, good bacteria are required to process it and get rid of it. Aeration expedites the process of oxidization, which is necessary to render the pollutants harmless. Decaying vegetation has no place to go, nothing to manufacture it into non-toxic matter, unless a pond aerator is put to work.
The total capacity of your pond needs to be circulated roughly every two hours for optimal circulation. Simply calculate the number of gallons of water your pond contains, and divide this number by two. This will give you the size of pump you require for adequate circulation and aeration.
You need to position the pump opposite to the filter or waterfall. Pond aerators for home use are reasonably priced for the job that they do, and it is not just recommended that you install one, but essential.
