Dealing with pool algae can quickly turn your backyard oasis into a green, murky disappointment. At Next Level Pool Service, we understand the frustration that comes with algae problems and offer comprehensive solutions to restore your swimming pool to crystal clear perfection.
Understanding Pool Algae
Algae can be more than just an eyesore—it can damage pool surfaces, clog filters, and throw off your water chemistry.
Inadequate circulation or filtration
Imbalanced water chemistry
Insufficient sanitizer levels
Warm temperatures
Introduction of contaminants
Algae is a common pool problem, especially in warmer climates like San Diego. It can quickly take over your pool if not addressed early. Here are the key signs you may have algae:
Discolored water (green, yellow, or cloudy)
Slimy or slick pool surfaces
Visible patches or streaks on walls, steps, or floors
Rapid chlorine loss despite regular dosing
Poor water circulation or filtration performance
Algae are microscopic aquatic organisms that can rapidly multiply in your swimming pool when conditions are favorable. These unwelcome visitors typically appear as green, black, or yellow-mustard discoloration in your pool water or on surfaces. Several factors contribute to algae growth:
Green Algae
The most common type
Turns water green and can spread quickly
Usually floats in the water or clings to walls
Often a result of poor circulation or low sanitizer levels
Yellow (Mustard) Algae
Appears as yellow or brown dust-like patches
Typically clings to shady areas or pool walls
More resistant to chlorine and can return easily if not treated thoroughly
Black Algae
Dark spots or patches with a protective outer layer
Grows deep into porous surfaces like plaster or grout
Very tough to eliminate and often requires brushing and chemical treatment
Pink Algae (technically not algae, but bacteria)
Slimy pink or red streaks often found around plumbing or in corners
Less common, but can be persistent without proper sanitation
Preventing Future Algae Problems
The best algae treatment is prevention. Our maintenance programs help keep your pool algae-free through:
Regular professional cleaning and maintenance
Proper chemical balancing and monitoring
Adequate filtration and circulation
Preventative algaecide treatments
Prompt attention to early warning signs
Our Effective Algae Treatment Process
When tackling a green pool or any algae infestation, our professional team follows a systematic approach:
Thorough Assessment: We identify the type of algae and the extent of the infestation.
Water Testing: Comprehensive testing determines chemical imbalances contributing to algae growth.
Brushing & Vacuuming: Physical removal of algae from surfaces breaks down colonies.
Shock Treatment: Application of appropriate algaecides and chlorine shock treatments.
Filtration Enhancement: Ensuring your filtration system is working optimally to remove dead algae.
Water Balance Restoration: Adjusting pH, alkalinity, and sanitizer levels to prevent recurrence.

Contact us online today or give us a call at 760-315-4379.
After algae treatment, cloudy water is common due to dead algae and chemical residue. At Next Level Pool Services, we follow a proven process: we vacuum the pool thoroughly, clean or backwash the filter, and add a clarifier to bind tiny particles so they can be filtered out. We also retest and balance the water to restore clarity and ensure it’s safe to swim.
We don’t recommend swimming right after algae treatment. It’s best to wait until the algae is completely gone, the water is clear, and the chemical levels—especially chlorine—are back within the safe range. We’ll let you know when it’s good to go.
Yes—shocking the pool with a high dose of chlorine is one of the most effective ways to kill algae. But it works best when combined with brushing, filtration, and chemical balancing. At Next Level, we handle the full treatment so the algae doesn’t come back.
It depends on how bad the algae problem is. Light green algae can often be cleared in a day or two. Heavy or black algae can take several days and multiple treatments. Either way, we stay on it until your pool is clean and crystal clear.
After trying to DIY my pool following online forums and YouTube videos, I couldn’t for the love of god get rid of the stubborn algae out of my pool. James came in, did his magic, my pool is now sparkling clean. Knowledge and experience are a key. They don’t just come in and clean your pool, they explain everything along the way. Highly recommended.
