Pond Aeration Instructions

Pond aeration is the single most important factor in the success of your pond. One of the critical components in the pods ecology is dissolved oxygen and it is what makes the pond clean and the life living there healthy.


Consequence of Low Oxygen Levels

The single most critical problem that is associated with low oxygen levels is that any fish living within the pond will die. There is a minimum requirement of dissolved oxygen that is measured in Parts Per Million, or PPM that they need or there simply will be no way for the pond to sustain life. Add to that the undesirable odors that are emitted from the pond when there is not enough oxygen as waste is broken down.


How Did the Oxygen Levels Get So Low?

Reasons behind how oxygen levels came to be so low in your pond can be numerous. More often than not, it is because there are too many plants in the water, most particularly algae. These same plants that can be good when present in moderation because they aid in the release of oxygen to the water, can be very bad when they take over the habitat. The other side of the coin is that the same plants that are releasing the oxygen during the day are the same ones that are using it up at night making too much of a good thing bad for your pond.

Other factors that reduce the oxygen levels are waste. The organic waste in your pond comes from dead plants, overfeeding of the fish within it, and fish waste among other things. This waste requires oxygen to help it break down properly. In the case where the waste load is high additional oxygen is necessary to keep up with the process.


Pond Aeration Systems

 There are 2 basic types of pond aeration systems that you will consider. The one that you choose will depend on the depth of your pond. So if your pond is less than 6 feet deep, then a surface aeration system will work well for you, and if it’s deeper than that, then you will like require a bottom aeration system.

  1. A surface pond aeration system will float in the pond, pull in water and spray it into the air transferring oxygen as the water comes back down into the pond. This also assists in venting any gases that may be present. The system draws the water from perhaps the top 1 foot or so of the pond and that’s why this system is recommended only for the shallow ponds.
  2. The pond aeration systems that work on the bottom of your pond work much differently and more efficiently. These systems force air into the pond bottom. The bubbles that are created are what actually do most of the work. As these bubbles work their way to the surface of your pond they mix the water that lacks oxygen with that which is rich. The only movement noticed on top of the water when using such a system is perhaps a slow and gentle rolling action across the surface.

    Armed with the required information such as the depth of your pond, and its overall size, conduct your research to find which system will be the one that is more suited to meet your needs. In many cases, it is advisable to contact a professional who knows about pond aeration systems and ask for their recommendations based on the pond characteristics you have given them. Depending on the type of system you select, it may require professional installation.
