Green Pool Treatment & Algae Removal
Fast and effective algae removal that turns your swamp-green pool back into crystal clear water

A green pool is more than just an eyesore. It is a sign that algae has taken over your water, and it means your pool is not safe for swimming. Algae grows fast in warm weather, especially when your water chemistry is out of balance or your circulation system is not working properly. What starts as a few green spots on your walls can quickly turn your entire pool into a murky swamp.
The good news is that green pools are fixable. We specialize in algae removal and have restored hundreds of green pools in Montebello and surrounding areas. Our treatment process kills the algae, clears the water, and gets your pool back to normal in just a few days. You do not need to drain your pool or spend thousands of dollars on new equipment. You just need the right treatment and a team that knows what they are doing.
Why Pools Turn Green
Understanding why your pool turned green helps prevent it from happening again. Here are the most common causes:
- Low Chlorine Levels: Chlorine kills algae and bacteria. When your chlorine drops too low, algae starts growing. This often happens after heavy rain, hot weather, or if you forget to add chemicals for a few weeks.
- Poor Circulation: Algae loves still water. If your pump is not running enough hours per day or your filter is clogged, water sits stagnant in corners and shaded areas where algae thrives.
- High Phosphate Levels: Phosphates are algae food. They come from leaves, dirt, fertilizer, and even some pool chemicals. High phosphate levels make it nearly impossible to keep algae under control.
- Unbalanced pH and Alkalinity: When your pH is too high or too low, chlorine does not work effectively. Your pool may have plenty of chlorine in it but still turn green because the chemistry is wrong.
- Extended Neglect: Life gets busy and sometimes pool maintenance gets pushed aside. Missing a few weeks of care can lead to algae blooms that are difficult to reverse without professional help.
Our Green Pool Treatment Process
We use a proven multi-step process to kill algae and restore your pool to crystal clear condition. The exact treatment depends on how severe your algae problem is, but here is what you can expect:
Step 1: Assessment and Testing
We start by testing your water chemistry and inspecting your pool equipment. We need to know your current chlorine, pH, alkalinity, and other levels to create the right treatment plan. We also check your filter and pump to make sure they are working correctly.
Step 2: Shock Treatment
We add a heavy dose of shock to your pool to kill the algae. This raises your chlorine level much higher than normal for a short period. The shock oxidizes the algae and starts the process of turning your water from green to cloudy to clear. Visit our homepage to learn more about our treatment methods.
Step 3: Algaecide Application
Along with shock, we add professional-grade algaecide that targets the specific type of algae in your pool. Different algae strains require different treatments, and we have the experience to know which products work best.
Step 4: Brushing and Circulation
We thoroughly brush all pool surfaces to loosen algae from the walls and floor. Then we ensure your pump and filter run continuously for 24 to 48 hours to circulate the chemicals and filter out dead algae. Proper circulation is critical for effective treatment.
Step 5: Vacuuming and Filter Cleaning
Once the algae is dead, we vacuum all the debris from your pool floor. We also clean your filter multiple times during the treatment process because dead algae quickly clogs filters and reduces their effectiveness. If you need more extensive filter cleaning or replacement, we can handle that too.
Step 6: Final Balancing and Follow-Up
After your water clears, we retest everything and make final adjustments to bring your chemistry into perfect balance. We often schedule a follow-up visit a few days later to make sure the algae has not returned and your water stays clear.
How Long Does Treatment Take?
Most green pools clear up within 3 to 7 days depending on the severity of the algae bloom. Light green water with minimal algae growth might clear in 2 to 3 days. Dark green swamp-like pools with heavy algae can take a full week or more to completely clear.
During the treatment period, your pool will go through several stages. First, the water turns cloudy as the algae dies. Then it slowly becomes clearer as your filter removes the dead algae particles. Finally, it returns to sparkling clear once all the debris is removed and your chemistry is balanced.
We stay in close contact with you throughout the process and let you know what to expect at each stage. We also provide instructions on running your pump and backwashing your filter between our visits. The key is patience. Trying to rush the process or swim too soon can stir up settled algae and make the problem worse.
Preventing Future Algae Growth
Once we restore your pool to clear condition, you want to keep it that way. The best way to prevent algae from returning is consistent maintenance. That means regular chemical testing, proper circulation, and routine cleaning.
Many of our green pool treatment customers choose to continue with weekly pool cleaning service after seeing how much work is involved in treating a green pool. Regular professional care prevents algae problems before they start and saves you time, money, and frustration in the long run.
If you prefer to maintain your pool yourself, we can teach you what to test, when to add chemicals, and how to spot early signs of algae growth. Either way, we are here to help you enjoy a clean, safe pool without the stress of dealing with algae blooms.
