3 Keys to Controlling Pond Algae

Homeowners add ponds to their homes for many reasons. Some build water gardens, many consider ponds interesting architectural elements and millions gain ponds when dirt is dug out to create home foundations. However, all kinds of ponds need help to remain free of algae. There are many options for controlling the unwelcome growths, but correct pond construction, balanced plant and animal life and aeration are keys.

Proper Construction Is Critical

The construction of a pond affects water quality, so careful attention to detail during the process is one of the most important pond algae solutions. Professionals who create ponds will ensure the best depth and add a minor slope to make debris removal easier. Ponds should be built so that rainwater cannot automatically flow across property and collect in them. Rain runoff tends to include organic matter that feeds algae. Yard chemicals and fertilizer can also run into ponds, creating imbalances.

The Right Mixture of Plants and Animals Is Essential

Adding a careful mix of plant life to a pond can help control algae. Many floating and underwater plants absorb the excess nutrients that promote algae growth. Plants use the nutrients for their own needs and starve algae. Floating plants like water lilies add shade, which cools the water and also starves algae of the light it needs. It is also critical not to overstock ponds with fish.

Pond Aerators Keep Water Healthy

One of the easiest and most effective ways to maintain good quality pond water is to use an aeration system. There are many models available, but they all work on the same principle. Aeration systems shoot water fountains or columns into the air, which increases dissolved oxygen and improves circulation. In the process many noxious gases are released. Algae is removed from the surface and driven into deeper areas, which deprives it of sunlight. As a bonus, aeration fountains can also create stunning effects, especially when combined with lighting systems.

Residential ponds can be elegant features or even recreational areas. However, homeowners need to control algae in order to maintain a pond’s water quality. There are many effective ways to do that, and 3 of the most important are to ensure correct pond construction, balance plant and animal life and use an aeration system.
