A green swimming pool is a common frustration for pool owners in Hampshire, especially when the weather gets warmer. Algae can quickly take over your pool, turning the water cloudy and unpleasant. Fortunately, by following a few key maintenance steps, you can ensure your pool stays clean, clear, and inviting all year long.
A green pool is usually caused by algae, which thrive in poorly maintained pools, especially when water chemistry is off balance or the filtration system isn’t working effectively. Algae can develop quickly, particularly after heavy rain or when pool maintenance is neglected for a while. The best way to prevent algae growth is by maintaining the right chemical balance, keeping the pool clean, and ensuring proper filtration. With regular care, your pool can stay crystal clear and algae-free. For professional pool services in Hampshire, check out our Swimming Pool Services.
Chlorine is your first line of defence against algae. When your pool’s chlorine levels drop below the recommended range, algae can quickly start to grow. To prevent green water, aim to maintain chlorine levels between 1-3 ppm (parts per million). Test your pool water regularly, especially in the warmer months, as higher temperatures and increased pool use can cause chlorine to dissipate faster. Proper chlorine levels not only kill bacteria and viruses but also keep algae in check. For more information on keeping your pool safe and healthy, visit our Swimming Pool Maintenance page.
Water chemistry is a critical factor in keeping your pool free from algae. In addition to chlorine, other factors like pH, alkalinity, and calcium hardness play a role in preventing algae growth. A pH level between 7.2 and 7.6 is ideal for effective chlorine use, while alkalinity should be maintained between 80-120 ppm.
Calcium hardness levels should fall between 200-400 ppm to prevent scaling and help keep your pool equipment in good condition. By testing and adjusting the water chemistry regularly, you can prevent algae from thriving and ensure your pool remains healthy. If you’re unsure about your pool’s chemistry, Total Pool Care offers expert water balancing services to keep your pool in top condition. Learn more on our Swimming Pool Services page.
Even with regular chlorine maintenance, your pool will benefit from occasional shocking—especially after heavy use, rainfall, or when the water looks cloudy. Pool shock involves adding a high dose of chlorine to kill algae spores and other organic contaminants. Shocking the pool once a week, or after a big pool party, ensures that chlorine can handle any contaminants that may have escaped regular treatment. It’s best to shock the pool in the evening when the sun is lower, allowing the shock to work effectively without being quickly dissipated by the heat. If you’re unsure about how to shock your pool properly, our team can assist you with professional pool care services. Visit our Swimming Pool Maintenance page for expert guidance.
Your pool’s filter is essential for removing dirt, debris, and algae spores from the water. To ensure your filter works effectively, it needs to run for 8-12 hours a day during the warmer months. Make sure to clean or backwash your filter regularly—clogged filters can’t properly remove contaminants, which can lead to cloudy or green water. If you have an older or inefficient filter, it might be worth having it inspected or replaced to ensure your pool’s water stays clear. If you need help with filter maintenance or advice on upgrading your system, our team at Total Pool Care can help. Check out our Swimming Pool Services for more information.
Algae can cling to pool walls, ladders, and steps, especially in shaded areas. To prevent algae from taking hold, it’s essential to brush your pool walls at least once a week. Brushing removes algae spores before they can grow and spread. Vacuuming the pool regularly is also crucial to remove debris and organic matter that algae feed on. By keeping your pool clean, you’ll reduce the chances of algae blooming and keep your pool looking pristine.

To fix a green pool quickly, shock the pool with chlorine, brush the pool’s walls and floor to remove algae, and run the filter continuously until the water clears up.
To prevent green pool water, maintain proper water chemistry, especially chlorine levels, and ensure the filtration system is working correctly. Regularly clean your pool and remove debris to keep algae at bay.
To prevent a green pool, use an algaecide regularly, keep chlorine levels within the ideal range, and clean your pool’s filter to ensure proper circulation and sanitation.
Chlorine can take anywhere from a few hours to a couple of days to eliminate algae and turn your pool water clear again, depending on the severity of the problem.
