Why Does My Pond Water Turn Green? Why Does My Pond Water Turn Green? 

Joanne – Evans City, PA

Green water is a form of algae called planktonic algae and there are quite a few factors causing your water to be clear during the winter and green as the weather warms up. The main reason is the interruption of the nitrogen cycle.

In order for algae to grow, it needs a food source (nutrients) and sunlight. During the colder winter months of the year, nutrients within the water are less likely to increase due to the fact that the digestive systems of fish have slowed to a point where little, if any, nutrients (fish waste) are being added. Also, during the colder months, algae and aquatic plants are not as active at consuming nutrients.

As the weather warms up, fish become active, digestive systems kick back in and nutrients begin pouring in and if not held in check using aquatic plants, natural bacteria and filtration, green water will develop.

If you have chronic green water and still can’t keep it in check, consider a UV or Ion clarifier.

  1. Please use UV as a last resort. It kills all bacteria, including those you need to eat waste, which produces nitrogen, which supports algae… etc, etc. Plants and animals (bacteria and fish) are the way to fight algae.
