Green Pool Treatment & Algae Removal
Turn your swampy green pool back to crystal clear blue with fast, effective algae treatment from Duncanville's pool restoration experts.
Why Your Pool Turned Green
Green pool water is caused by algae growth. Algae are microscopic plants that thrive in warm, sunny conditions with improper chemical balance. Here in Texas, algae can take over a pool in just a few days when chlorine levels drop too low or pH gets out of range.
Common causes include equipment failure like a broken pump or clogged filter, missed chemical treatments during vacation or busy periods, heavy rain that dilutes chemicals and brings in contaminants, debris accumulation that feeds algae growth, or simply not maintaining regular pool service. Whatever the reason, algae spread quickly once they get established.
Many homeowners try DIY solutions they find online or at pool stores. They shock the pool once, brush a little, and hope for the best. Unfortunately, stubborn algae require more aggressive treatment with professional knowledge and equipment. That's where our expert pool treatment services make the difference between wasting money on ineffective chemicals and actually fixing the problem.
Our Green Pool Treatment Process
We follow a proven process that kills algae, removes dead plant matter, and restores your pool to safe swimming condition. This isn't guesswork. It's a systematic approach based on years of experience treating green pools throughout Duncanville.
Step-by-Step Algae Elimination
- Initial assessment: We identify the type of algae in your pool (green, mustard, or black) and determine the severity of the infestation. This tells us which chemicals and techniques will work best.
- Remove large debris: We clear out leaves, branches, and visible matter that can interfere with chemical treatment and provide food for algae.
- Brush all surfaces: We thoroughly brush walls, floors, steps, and corners to break up algae colonies and expose them to chemicals. This is crucial for treatment success.
- Balance pH levels: We test and adjust pH to the ideal range for chlorine effectiveness. Shock treatment doesn't work properly if pH is too high or low.
- Shock treatment: We add large amounts of concentrated chlorine or non-chlorine shock to kill algae and oxidize organic matter. The pool may turn cloudy or milky at this stage, which is normal.
- Add algaecide: We apply professional-grade algaecide that prevents regrowth while shock treatment works. This is insurance against algae coming back during recovery.
- Run filtration continuously: We ensure your pump and filter run 24 hours a day during treatment to remove dead algae and circulate chemicals throughout the water.
- Clean filter regularly: We backwash or clean your filter multiple times as it captures dead algae. A clogged filter can't do its job, so this step is essential.
- Vacuum dead algae: Once algae are dead and settled, we vacuum waste to remove it from your pool instead of sending it back through the filter.
- Rebalance chemistry: We test and adjust all chemical levels to normal ranges for safe, comfortable swimming water.
Depending on how green your pool is, this process takes 3 to 7 days. Light algae might clear in 3 days. Heavy infestation can take a full week. We'll visit multiple times during treatment to monitor progress, add chemicals, and clean your filter. If your filter needs deep cleaning or replacement, we can handle that too with our filter service.
Types of Pool Algae We Treat
Not all algae are the same. Different types require different treatment approaches. We've dealt with every variety in Duncanville pools and know exactly how to eliminate each one.
Green algae (most common): This is the typical algae that makes your water look like a swamp. It floats freely in the water and clings to walls. Green algae respond well to standard shock treatment and usually clear within a few days with proper care.
Mustard algae (yellow/brown): This algae looks like dirt or sand on your pool floor and walls. It's more resistant to chlorine than green algae and requires stronger treatment plus aggressive brushing. Mustard algae can survive in shady areas of your pool even when chlorine levels seem fine.
Black algae (most stubborn): These are actually blue-green bacteria with protective layers that make them extremely difficult to kill. They appear as dark spots on pool surfaces, especially plaster. Black algae have roots that penetrate surfaces and require intensive scrubbing plus concentrated chemical treatment. Some cases need repeated treatments over weeks to fully eradicate.
We identify which type you have and use the appropriate chemicals, tools, and techniques to eliminate it completely. We also explain how to prevent that specific type from returning so you don't face the same problem again.
Preventing Future Algae Growth
Once your pool is clear again, you want it to stay that way. Algae prevention is much easier and cheaper than treatment. Here's what actually works to keep algae from coming back.
Maintain proper chlorine levels: Consistent sanitizer levels are your best defense against algae. Test your water at least twice a week and adjust as needed. Free chlorine should stay between 1 and 3 ppm for routine maintenance.
Keep pH balanced: When pH climbs above 7.8, chlorine becomes less effective at killing algae. Test pH regularly and use pH reducer when needed to keep levels between 7.2 and 7.6.
Run your pump daily: Stagnant water promotes algae growth. Your pump should run at least 8 to 12 hours per day during warm weather to circulate water and chemicals throughout the pool.
Brush and vacuum weekly: Regular physical cleaning removes algae spores before they can multiply and prevents debris buildup that feeds algae growth.
Clean your filter regularly: A dirty filter can't remove algae spores and contaminants effectively. Backwash or clean your filter according to manufacturer recommendations.
The easiest prevention method is simply signing up for our weekly pool cleaning service. We handle all the testing, chemical balancing, and cleaning that prevents algae from ever getting started.
