Why Should You Aerate Your Pond?

The ideal pond supports a healthy assortment of aquatic animal life, has clear water and is spotted with beautiful plants. However, there are a lot of natural environmental factors working against ponds. Erosion and weather can quickly turn a beautiful pond into an algae-filled swamp. Chemical treatments are available to restore a pond to its natural beauty, but these can be expensive and sometimes detrimental to the environment. Proper pond management, including installing an aeration system, is a natural way to restore balance.

Some aeration systems also include a fountain, which adds a nice focal point to the area. However, be careful with fountains. The main goal of aerating a pond is to mix the lower and upper levels of water. Some fountains sit on top of the water and do not pull from lower levels. They do little to improve the health of a pond. 

Promotes Healthy Wildlife

Every living creature needs oxygen, even aquatic animals. Ponds naturally receive oxygen at the surface of the water, where air diffuses into the water. However, sometimes this is not enough. Oxygen also needs to get to the bottom of the pond. If stratification develops, then oxygen never makes it past the top layer. Wildlife living at the bottom of the pond will not get the oxygen it needs. Stratification occurs when the top layer of the water gets warmed by the sun and the bottom layers remain cold. The different layers of water don’t mix, and oxygen from the surface of the water doesn’t circulate to the bottom. By aerating the water, oxygen is spread to all areas of the pond where wildlife may live. 

Reduces Pond Algae

Algae grow in hot, stagnant water. By aerating pond water, warm top levels of water mix with cooler lower levels. This deprives the algae of sunlight by pushing it down into cooler levels. Aeration also helps reduce phosphorus, which algae need to grow. Oxidation causes phosphorus to bind with iron molecules. The iron molecules sink, dragging the phosphorus molecules to the bottom of the pond where it is not used by plants and algae. 

Improves Water Quality

Sediment on the bottom of a pond releases harmful gasses and metals. Aeration pushes them up and out into the air, instead of allowing them to collect at the bottom. This helps to stabilize the pH levels of the water. It also helps remove carbon dioxide from the water. These elements, left unchecked, can cost lots of money to remove through water treatment options.

By keeping the water in a pond moving and circulating, it will stay clear, clean and healthy.
