The growth of green algae in indoor swimming pools often poses challenges. Green algae not only impact water quality but also make the pool bottom slippery, increasing the risk of accidents. It is crucial to implement scientific and effective prevention and control measures against the occurrence of green algae in indoor swimming pools. This article aims to guide the management of green algae, ensuring swimmers can enjoy a safe and hygienic swimming environment.
Causes of algae growth in indoor swimming pools
There are many causes of algae growing in indoor swimming pools, especially private swimming pools. In private swimming pools, they are easier to clean because they are smaller, but the growth of algae is related to water quality management and disinfection systems.
First of all, the water volume of private swimming pools is not large, and it can usually be drained, cleaned, and refilled with water. However, if the water is not treated properly, it can easily lead to the growth of algae. One of the biggest problems is the lack of adequate disinfectants in water supplies. Due to the lack of efficient disinfectants, bacteria and algae will grow in the water, which will affect the quality of the water.
In addition, the imbalance of water pH is also an important factor causing the growth of algae in indoor swimming pools. When the pH value of the water body is too high or too low, it is conducive to the growth of algae. Therefore, regular monitoring and adjustment of water pH is an important measure to prevent algae growth.
In addition, whether the indoor swimming pool is equipped with an automatic disinfection system is also a key factor. Automatic disinfection systems release disinfectants steadily and evenly, helping to keep water clean. If there is no automatic disinfection system, sufficient residual chlorine should be added manually to avoid the reproduction of algae and other harmful organisms.
How to deal with green algae problems in swimming pools
1. Maintain sufficient residual chlorine: During the disinfection process, it is necessary to ensure that the residual chlorine in the swimming pool is maintained at the specified standard. Sufficient residual chlorine can effectively inhibit the growth of green algae.
2. Turn on circulation equipment regularly: Be sure to turn on the circulation device frequently to allow the water to flow evenly. This can effectively disperse the disinfectant and effectively prevent the residual chlorine content in some areas from being too low, thereby inhibiting the growth of green algae.
3. Automatic dosing device: If your swimming pool is equipped with an automatic dosing device, it can automatically detect residual chlorine levels and add disinfectant to the water if necessary. This helps avoid water quality problems caused by being away for extended periods of time.
4. Use the algaecide copper sulfate: When the problem of green algae in swimming pool water is serious, you can consider using copper sulfate algaecide.Pour copper sulfate into the water in an amount not exceeding one gram per cubic meter of water.
5. Circulation equipment mixing: Turn on the circulation device to fully stir the pool water, ensuring the even distribution of copper sulfate in the swimming pool and enhancing the killing effect on algae.
6. Add precipitant aluminum sulfate: After waiting for two hours, add the precipitant aluminum sulfate and add it evenly into the pool water at a dosage of no more than 10 grams per cubic meter of water. Turn the device on again and allow the aluminum sulfate to mix thoroughly with the water.
Detailed steps for dealing with algae problems in your swimming pool are as follows
1. Stop circulation equipment: Once green algae is found, the water circulation system in the swimming pool should be shut down immediately to keep the water in a calm state to facilitate the next step of settlement. It is recommended to pause for a minimum of 5 hours.
2. Observe algae precipitation: Monitor the pool water while the circulation equipment is stopped. Because the water flow is still, the dead algae settles on the bottom.
3. Clean up the sediment: After a certain period of time, use appropriate tools to clear the algae deposits from the bottom of the pool. This is a critical step in ensuring clear water.
4. Adjust water alkalinity: Note that during this time, the water is alkaline. In order to achieve the purpose of neutralization, a neutralizing agent can be added to the water. The most commonly used is the plant acid oxalic acid. The amount added is about 3 to 5 grams/cubic water to adjust the pH of the swimming pool.
5. Replenish water level: After adjusting the water quality, add water to the swimming pool to bring the water level back to its original position.
6. Detect residual chlorine and start automatic disinfection device: Finally, test the pool water for residual chlorine. If the remaining chlorine is not enough, add it in time. If the swimming pool has automatic disinfection equipment, it should be ensured that it can start automatically.
7. Keep the circulation equipment running normally: Make sure the swimming pool’s circulation equipment is running on time every day to ensure even circulation of the water. This helps disperse the disinfectant and prevent green algae from growing again.
Keeping the water quality of indoor swimming pools clean is the top priority to ensure the health and safety of swimmers. When affected by green algae, immediate implementation of scientific and effective removal and protection measures is crucial. This will not only preserve water quality but also enhance the overall swimming experience. Regular monitoring of water quality, adding suitable disinfectants, and ensuring proper water circulation are essential steps in preventing the growth of green algae.
