Most people know that swimming pools are great for relaxing, cooling off, and spending time with family and friends. However, did you know that pools play an important role in the food chain? You might be surprised to learn what aquatic creatures live in and around swimming pools, and how they depend on these water bodies for survival.

The role that pools play in the food chain starts with the tiny algae that live in the pool water. These tiny algae eaters are primarily responsible for maintaining the healthy balance of nature in the water, consuming excess nitrogen and phosphorous which would otherwise contribute to algae growth and subsequently damage the ecosystem.

Birds and fish are also creatures that live mainly in water, and they love diving into crystal clear pools for a drink. Unfortunately, fish are also very sensitive to pollution, and much of what they consume is carried via the food that we eat. That is why it is extremely important that we limit the amount of toxins and chemicals that we discharge into the water bodies that we regularly use.

Pools can also become home to parasites and diseases, some of which can be transferred to humans via the water that we consume. Some diseases that are prevalent in pools are Giardia, Cryptosporidium, and Amoebaes. Keeping your pool clean by regularly treating it with a water purifier is the best way to prevent these and other diseases that live in or around fresh water. In addition, regular cleaning ensures that the bathers will experience a safe and enjoyable swimming experience. If you are interested in keeping your pool clean, consider getting a pool filter.


Did you know that algae is responsible for most of the color variation in fresh water? Depending on the source and amount of light, the color of the water can change from transparent to a dark, tinted green. While some algae is actually beneficial and can assist in the production of oxygen, others cause damage as they feed on submerged plants and animals. One of the more common types of algae is green algae, which is responsible for the tinted color of your pool water.

Algae is probably the most important aquatic organism. It is responsible for consuming excess nutrients which would otherwise contribute to blooms of other, possibly harmful, organisms. Did you know that algae blooms are usually triggered by heavy rain and rising temperatures? Rising temperatures cause the liquid contents of your pool to change, making it more suitable for algae growth. Rain helps to flush nutrients from the soil that become available for algae to utilize. As a result, algae blooms can be extremely harmful to the ecosystem. If you would like to keep your pool clean, it would be wise to keep an eye on the water for signs of algae growth, and take measures to prevent it.


Amoebaes are a type of single-cell organism that lives in the waters of lakes, ponds, and the ocean. Amoebaes are known to feast on bacteria and other smaller organisms, using the process of phagocytosis to ingest and digest its prey. They can also reproduce rapidly, creating a thick layer of slime which may damage the ecosystem if not removed regularly. Although they are smaller than many large fish, amoebaes are capable of causing major hurt if they feel threatened or cornered.


While we are talking about food, it is important to acknowledge that the birds are also very sensitive to the balance of nature in the water. Did you know that the number of birds that flock to your pool area may be a sign of how healthy it is? More specifically, the bird droppings that they leave behind can indicate how well the ecosystem is functioning. When birds find food in abundance, the ecosystem is considered to be in good health.

Did you know that many bird species require a regular food supply to prevent them from going hungry? The more food in abundance, the more likely they are to make their presence known by visiting your pool area. However, too many nutrients can cause algae blooms which will in turn damage the food supply for the birds. Keep an eye on the quantity and type of food that is provided for the birds near your area, and consider ways to improve the ecosystem for everyone’s benefit.


Fish are actually one of the main groups of creatures that depend on healthy, clear water for survival. Did you know that without fish, the food chain would be significantly damaged? Did you know that certain species of fish are known to play an important role in the protection of waterways and are regularly used to combat water pollution?

It is estimated that there are over 150 different types of fish that reside in the oceans, and due to climate change, some fish species are beginning to be affected and are looking for new places to live. When this happens, the need for clean water increases, as these fish are usually looking for somewhere more tranquil and unpolluted to make their home. Unfortunately, pollutants such as heavy metals, oil, and fertilizers can cause these fish to become ill, and if they are not removed, these pollutants will eventually cause the fish to starve.

Clean water is essential for the survival of all aquatic creatures, including humans. Therefore, it is important to maintain the health of our natural resources by keeping our pools clean. Using a water purification system is the simplest and most efficient way to ensure that the pool is always clean, and this in turn will contribute to the health of the ecosystem.
