What is Algae
Algae are simple, photosynthetic organisms found in aquatic environments. While they play a crucial role in ecosystems by producing oxygen and serving as food for aquatic life, certain types of algae can become problematic in confined spaces like swimming pools. There are several types of algae commonly found in natural bodies of water, including:
-Green Algae
-Brown Algae
-Black Algae
-Mustard Algae
The most common algaes that we see are green and mustard-yellow algae. Black algae is less common but more difficult to remove. It is rare that we see brown algae here in North Georgia.
How Algae from Lakes Enter Swimming Pools
The transfer of algae from lakes to swimming pools can occur through several pathways, including:
Swimmers
When people swim in lakes and then enter a swimming pool, they can unknowingly carry algae spores or fragments on their bodies, swimsuits, or towels.
Wind and Water Flow
Algae from nearby lakes or ponds can be blown into the pool area by the wind. Additionally, if a swimming pool is located near a lake, rainwater or runoff can carry algae spores into the pool.
Contaminated Equipment
Pool maintenance equipment such as skimmers, brushes, and hoses that have been used in lake water can also be a source of algae transfer.
Surrounding Environment
If a pool is located near a body of water, such as a lake or river, algae can easily be transferred through water movement, especially during stormy weather or periods of high winds. The type of algae that is transferred from a lake into a swimming pool is generally going to be a black algae. This is not an algae that grows in your pool when there isn’t sufficient chlorine in the pool.
Risks of Algae in Swimming Pools
Health Hazards
Certain types of algae, especially blue-green algae, can produce toxins that may pose serious health risks to swimmers, including skin irritation, respiratory issues, and gastrointestinal illnesses. Cyanobacteria (blue-green algae) is of particular concern because it can produce harmful microcystins, which are potent liver toxins.
Aesthetic Problems
Algae growth in a pool can turn the water cloudy or green, which not only ruins the swimming experience but also makes the pool look unkempt. Algae buildup on pool walls, floors, and tiles can be difficult to remove and may require extensive cleaning. Also, to properly remove algae
Slippery Surfaces
Algae on pool surfaces can make them dangerously slippery. Algae increases the risk of slips and falls, particularly around the pool’s edge or in shallow areas where algae may grow undetected.
Clogged Filtration System
Algae, if left unchecked, can clog the pool’s filtration system. Over time, this reduces the pool’s ability to circulate water effectively, leading to poor water quality and increased maintenance costs. When algae is not controlled, it can easily cost several hundred dollars to remove and have the pool returned to crystal clear.
Preventing the Transfer of Algae from Lakes to Pools
Prevention is key when it comes to managing algae growth in swimming pools. Here are some practical steps to reduce the likelihood of algae transfer:
Limit Exposure
If you live near a lake, it’s essential to minimize direct contact between your pool and the surrounding environment. Consider installing physical barriers, such as fences or vegetation, to prevent algae from blowing into your pool. Properly covering your pool when it’s not in use can also help prevent algae from being transferred by wind or rain.
Keep Equipment Clean
Regularly clean any equipment used in both the lake and the pool. This includes pool skimmers, brushes, and hoses. It is our recommendation as pool professionals that pool toys, swimming suits should be only used in the pool and not in any other body of water.
Professional Tip: When we are treating a pool that has green algae, we will remove any pool robots from the pool before treating the pool. We won’t put the equipment back into the pool until the pool is clear. Once the pool is clear, we will put the robot back in the pool, but not before checking it to make sure there isn’t any algae on the equipment.
Shower Before Swimming
Encourage swimmers to shower before using the pool. This helps remove any algae spores or debris that might have been carried from the lake on their body or swimsuit. Even if you shower before swimming the risk is still there.
Maintain Proper Pool Chemistry
Regular testing and balancing of the pool’s pH, chlorine levels, and alkalinity can discourage algae growth. Keeping the water properly sanitized and balanced with a continuous chlorine output is one of the most effective methods to prevent algae.
Use Algaecides
Regular use of algaecides can be helpful in controlling the growth of algae in pools. These chemicals prevent algae spores from taking root and multiplying in the water. We only recommend using algaecides unless it is absolutely necessary. Overuse of algaecides can cause your pool to have an issue with metals.
Optimize Pool Circulation
Ensure that your pool’s filtration system is working correctly and that the water is being adequately circulated. Algae thrive in stagnant, still water, so keeping the water moving is a simple but effective preventative measure.
Routine Maintenance
Regular pool maintenance, including vacuuming the pool, scrubbing the pool walls, and removing debris, is essential for preventing algae buildup. Don’t forget to clean your pool filter regularly to maintain water flow.
