Green Pool Treatment & Algae Removal

Why Pools Turn Green and What It Means

A green pool is one of the most common and frustrating problems pool owners face. That green color comes from algae, tiny plants that thrive in water when conditions are right. Algae grows fast in warm weather, which is why pools in Cypress, CA can turn green seemingly overnight, especially during summer months.

Several things cause algae to take over your pool. Low chlorine levels are the most common culprit. When your sanitizer drops too low, algae spores that are always present in the air find a perfect home in your pool water. Poor circulation, clogged filters, and unbalanced pH levels also create ideal conditions for algae growth.

Many people panic when they see their pool turn green, but the good news is that we can fix it. With the right treatment process and professional equipment, we restore your pool to crystal clear water in just a few days. The key is acting quickly before the algae problem gets worse.

How We Eliminate Algae and Restore Your Pool

Our green pool treatment process is systematic and proven effective. We do not just dump chemicals in and hope for the best. We follow a specific sequence that kills algae, removes dead organic matter, and prevents it from coming back. Here is what we do:

• Initial Assessment: We test your water chemistry and inspect your pool to determine the severity of the algae bloom and identify the specific type
• Debris Removal: We remove all visible debris, leaves, and floating material from the surface and bottom
• Chemical Shock Treatment: We add a powerful dose of shock treatment to kill the algae and oxidize organic matter in the water
• Algaecide Application: We apply professional-grade algaecide to target stubborn algae and prevent regrowth
• Intensive Brushing: We thoroughly brush all pool surfaces to break up algae colonies and help chemicals reach every area
• Filter Cleaning: We clean or backwash your filter to remove dead algae and restore proper filtration
• Continuous Circulation: We ensure your pump runs continuously to circulate chemicals throughout the pool
• Vacuuming and Final Balancing: Once the algae is dead, we vacuum up all debris and balance your water chemistry perfectly

The entire process typically takes 3 to 5 days from start to finish, depending on how severe the algae problem is. We check on your pool multiple times during treatment to monitor progress and make adjustments as needed.

Different Types of Algae and How We Handle Each One

Not all algae is the same. The treatment approach varies depending on which type has invaded your pool. Green algae is the most common type and usually the easiest to treat. It floats freely in the water and gives your pool that characteristic green color. With proper shocking and filtration, green algae clears up relatively quickly.

Yellow or mustard algae looks like sand or pollen on your pool floor and walls. It resists normal chlorine levels and often returns even after treatment if not handled correctly. We use specialized chemicals and more aggressive brushing to eliminate yellow algae completely.

Black algae is the most stubborn and difficult to remove. It forms dark spots that root deep into your pool plaster or grout lines. The outer layer protects the organism underneath, making it resistant to normal treatments. We use aggressive scrubbing with wire brushes and concentrated chemicals to penetrate and kill black algae at the roots.

Our technicians can identify which type of algae you have and apply the right treatment method. We have dealt with every algae situation imaginable in Cypress pools. After treatment, we can set you up with regular maintenance service to prevent algae from ever coming back.

Preventing Future Algae Problems

Once we clear up your green pool, you want to make sure it stays that way. Prevention is much easier and cheaper than treatment. The most important factor is maintaining proper chlorine levels at all times. Your chlorine should stay between 1 and 3 parts per million consistently.

Regular brushing and circulation prevent algae from getting established. Algae needs still water and surfaces to cling to. When you run your pump daily and brush your walls weekly, you disrupt these conditions. Clean filters are also essential because clogged filters reduce circulation and allow algae to thrive.

Keep your water balanced with proper pH levels between 7.2 and 7.6. When pH gets too high, chlorine becomes less effective at killing algae. Regular water testing catches these imbalances before they become problems. If your pool has had algae issues, consider using a maintenance dose of algaecide as an extra layer of protection.

Many of our customers find that professional weekly service is the easiest way to prevent algae. We test and balance your water, maintain proper chemical levels, and catch potential problems early. This costs far less than repeatedly treating algae blooms. If you notice your pool turning cloudy or getting a greenish tint, call us immediately. Early intervention prevents full algae blooms. We also offer filter cleaning services to keep your circulation system working effectively.
