As a pool owner, there’s nothing more inviting than a sparkling blue pool on a hot day. But sometimes, things don’t go as planned, and your pool water might turn green. A green pool isn’t just an eyesore – it’s also a sign of trouble that can make swimming unsafe. The good news is that with proper care and quick action, you can prevent and manage green pools effectively.

At Infinity Pool Solutions, we’ve helped many pool owners reclaim their pools from a green invasion. Let’s dive into why pools turn green, why it’s important to address it, and how you can keep your water clean and clear all season long.
Why Do Pools Turn Green?
The main culprit behind green pool water is algae. Algae are tiny plant-like organisms that love warm, still water. While small amounts of algae are natural, they can quickly multiply and take over your pool if the conditions are right. Here’s what can cause algae to bloom in your pool:
Imbalanced Chemicals: Your pool’s water needs the right balance of chlorine, pH, and other chemicals to stay clean. If the chlorine level drops too low or the pH goes out of balance, algae can thrive.
Poor Circulation: Your pool pump and filter help move water and filter out contaminants. If the system isn’t working properly, areas of still water become the perfect breeding ground for algae.
Debris in the Pool: Leaves, dirt, and other debris can introduce algae spores into your pool, giving them a head start.
Hot Weather: Algae grow faster in warm water, which is why green pools are more common in the summer.
Why is a Green Pool a Problem?
It might be tempting to ignore a green pool, especially if you’re not swimming in it right now. But letting the problem go can create bigger issues:
Health Risks: Green pools can harbor harmful bacteria alongside algae. Swimming in contaminated water can lead to skin irritations, ear infections, and stomach problems.
Damaged Pool Equipment: Algae and debris can clog your filter, pump, and other equipment, making them less efficient and shortening their lifespan.
Higher Cleanup Costs: The longer algae sit in your pool, the harder (and more expensive) it becomes to clean.
How to Prevent a Green Pool
The best way to deal with a green pool is to stop it from happening in the first place. Here are some tips to keep algae at bay:
1. Maintain Proper Chemical Levels
Regularly test your pool water to ensure the chlorine, pH, and alkalinity levels are balanced. Chlorine is your first line of defense against algae, so don’t let its levels dip too low.
2. Run Your Pool Pump
Keep your pump running for at least 8-12 hours a day to ensure proper water circulation. This helps distribute chemicals evenly and prevents still water where algae can grow.
3. Clean Your Pool Regularly
Skim leaves and debris from the surface, vacuum the bottom of the pool, and scrub the walls to remove algae spores before they take hold.
4. Shock Your Pool Weekly
“Shocking” your pool means adding a higher dose of chlorine to kill bacteria and algae. This is especially important after heavy use or storms.
5. Invest in Algaecide
Algaecide is a chemical designed to prevent algae growth. Use it as a preventative measure, especially during warm weather or if your pool has had algae problems before.
How to Fix a Green Pool
If your pool has already turned green, don’t worry! Here’s how we can help to bring it back to its sparkling blue glory:
Step 1: Test and Balance the Water
Use a pool testing kit to check the chlorine, pH, and alkalinity levels. Adjust them as needed to create the right environment for cleaning up the algae.
Step 2: Brush and Vacuum the Pool
Scrub the walls, steps, and floor of your pool to break up algae. Vacuum up debris to prevent it from spreading.
Step 3: Shock the Pool
Add a large dose of chlorine (or a pool shock product) to kill the algae. Follow the manufacturer’s instructions and don’t swim until the chlorine levels return to normal.
Step 4: Run the Pump and Filter
Keep your pump and filter running continuously until the water clears. Clean the filter frequently to remove trapped algae.
Step 5: Add Algaecide (Optional)
For stubborn algae, use a specialized algaecide to give your pool an extra boost.
The Cost of Not Taking Action
If a green pool isn’t addressed quickly, it can lead to more expensive repairs and maintenance down the line. A neglected pool may require professional draining and acid washing, costing hundreds or even thousands of dollars. Staying on top of pool care not only saves money but also protects your investment in the long run.
