What Causes the Growth of Algae in a Pond?
The growth of algae on a pond is evidence that the pond’s ecology is unbalanced. There are many causes of such a disturbance, which can include an excess of nutrients or low oxygen levels. The sources of these can be due to dead plant matter and other organic waste from plants or animals. As these materials build up, they create the perfect breeding ground for algae growth. In a healthy pond environment with correct oxygen levels, excess plant and animal matter are broken down before algae are able to grow. In ponds where this is not occurring, the oxygen level is unable to keep up with the growing amount of decomposing matter, thus causing algae growth. As the algae grow and take over the pond, it will use the oxygen in the pond, taking it away from pond fish and decorative plants. If algae growth is allowed to continue, it will eventually kill the fish and other plants as it consume all of the ponds oxygen and other nutrients. Algae in ponds are usually due to stagnant pond water thi
