The Most Common Pool Problems and Solutions

1. Algae Growth: Causes, Prevention, and Treatment

Unchecked algae growth can quickly turn your pool into an unsightly, unhygienic environment. Algae thrive in warm, stagnant water, especially when proper maintenance is neglected. Different species—such as green, yellow (mustard), and black algae—each present unique challenges and require specific treatments. However, the good news is that algae problems can be avoided entirely with a proactive approach. This section dives into everything you need to know to keep your pool algae-free.

What Causes Algae Growth?

Algae spores are naturally present in the environment and can enter your pool through wind, rain, or even on swimsuits and pool equipment. When water chemistry is unbalanced—such as low chlorine levels, poor circulation, or pH outside the ideal range—algae can take hold and multiply rapidly. Warm temperatures and sunlight further encourage growth, making routine maintenance essential, especially during the summer months.

Steps to Prevent and Treat Algae:

• Maintain Proper Chlorine Levels. Consistently keep free chlorine between 2-4 ppm to prevent algae from settling. If algae appear, a shock treatment will help eradicate it. 
• Use HASA Sani-Clor® Sodium Hypochlorite. HASA’s liquid chlorine delivers proven, eco-friendly cleaning power to keep algae at bay. 
• Supplement with Algaecides. Persistent issues may require targeted solutions like copper-based or poly-quat algaecides. 
• Brush and Circulate. Regularly brush pool surfaces, including steps and corners, to disrupt algae. Keep water moving with a properly sized and maintained circulation system. 

Efficient algae prevention not only ensures a clean swimming environment but also reduces the chemical load, aligning with sustainable practices HASA supports.

2. Cloudy Water 

Cloudy pool water not only diminishes your pool’s visual appeal but also compromises disinfection and swimmer safety, making it critical to address the issue promptly. The root causes of cloudy water often include chemical imbalances, inadequate filtration, or the presence of fine particles and contaminants. It’s important to identify the source and take specific steps to restore crystal-clear water. 

Causes of Cloudy Water:

• Chemical Imbalances: When chlorine levels, pH, alkalinity, or calcium hardness are out of range, it can cause particles to remain suspended in the water instead of being filtered out. 
• Poor Filtration: A dirty pool filter, clogged filter media, or inadequate flow rate prevents your pool’s filtration system from effectively removing debris and fine particles that cause cloudiness. 
• Organic Contaminants: Environmental debris, sunscreen, body oils, and algae can all add to a cloudy appearance, especially if your pool’s sanitizer levels are too low to break them down completely. 
• High Bather Load: A crowded pool introduces higher amounts of dirt, sweat, and oils into the water, which can overwhelm the filtration and sanitation systems. 

Solutions for Clear Water:

• Inspect and Maintain Your Filtration System: 

Your pool filter is the backbone of water clarity. Check for issues such as a dirty filter cartridge, clogged sand, or insufficient pump flow. Regularly clean, backwash, or replace filter media as needed to keep the system functioning at peak efficiency. Consider upgrading to a high-capacity filter for better performance if you experience recurring cloudiness. 

• Test and Balance Your Pool Chemistry: 

Perform regular water tests to monitor key chemical levels. The ideal ranges are: 

• Chlorine: 1–3 ppm 
• pH: 7.4–7.6 
• Total Alkalinity: 80–120 ppm 
• Calcium Hardness: 200–400 ppm 

Imbalances in any of these parameters can lead to cloudy water. Use high-quality pool chemicals, like those from HASA, to correct these levels. For example, if your chlorine is low, consider using a liquid chlorine treatment for quick results without adding stabilizer where it’s not needed. 

• Use a Pool Clarifier for a Polished Finish: 

Clarifiers help bind fine particles and contaminants into larger clusters that your filter can trap more effectively. Look for natural, chitosan-based clarifiers, as they are safe for your pool and less likely to clog filters compared to synthetic products. Avoid overusing clarifiers, as excessive amounts may worsen the problem by creating residue in the water. 

• Shock Your Pool: 

If the cloudiness persists, it may be time for a shock treatment. Pool shock eliminates organic contaminants and restores sanitizer efficacy. Be sure to follow the manufacturer’s instructions to avoid over-chlorination, which can lead to other water quality issues. 

• Brush and Vacuum Regularly: 

Dead algae, fine sediment, or other debris can settle on pool surfaces, contributing to dull or cloudy water. Brushing the pool walls and vacuuming weekly ensures these particles are removed before they become a problem. 

Preventative Tips for Long-Term Clarity:

• Run your pool pump for at least 8–12 hours a day during pool season to ensure proper circulation and filtration. 
• Skim your pool daily to remove leaves and debris that could lead to algae growth if left unchecked. 
• Encourage swimmers to rinse off before entering the pool to reduce contaminants like oils and sunscreen. 
• Invest in a pool cover to keep debris out and maintain balanced water chemistry between uses. 

Maintaining water balance and achieving crystal-clear pool water doesn’t have to be complicated. Using liquid pool chemicals can simplify upkeep while reducing plastic waste through innovative recycling systems. With the right combination of regular maintenance, quality products, and proactive care, it’s easy to enjoy a pristine pool all season long..

3. Imbalanced Water Chemistry 

Water chemistry governs everything from swimmer comfort to equipment longevity. Corrosive or scaling water can harm pool finishes, pipes, and filters.

Balancing Tips:

• Regular Testing. Pay special attention to pH, total alkalinity, and calcium hardness. Utilize tools like the Langelier Saturation Index (LSI) to check for potential scaling or corrosion. HASA’s pool professionals recommend proactive testing, especially during seasonal changes. 
• Precise Calcium Management. Low calcium levels promote etching, while high levels encourage scale—both of which impact pool aesthetics and operations. Use calcium increasers or reducers to dial in a balanced level. 
  
  

4. Equipment Problems 

A poorly functioning pump or filter directly impacts water quality. Common issues include clogged filters, inadequate pump flow, or undersized systems.

Key Maintenance Practices:

• Clean Filters Regularly. Make sure to backwash sand filters or clean cartridge/DE filters when pressure rises by 8-10 psi. Replace filter media as per manufacturer guidelines. 
• Optimize Circulation. Ensure your pump size matches your pool’s requirements for turnover cycles. HASA recommends consulting a professional for proper pump and filter sizing. 
• Inspect Your Equipment. Regularly check for leaks, unusual vibrations, or malfunctioning components, repairing or replacing faulty parts quickly. 
  
  

5. Pool Stains 

Stains detract from your pool’s appearance and can have various causes, such as metals in source water, organic debris, or chemical imbalances.

Resolving Stains:

• Organic Stains. Remove tannin-based stains (caused by leaves or organic debris) using a targeted chlorine application or pool stain eraser tools. 
• Metal Stains. Prevent these stains by using a sequestering agent to keep metal ions in solution. HASA’s products reduce the risk of metals precipitating and staining surfaces. 
• Proactive Care. Consistently monitor pH and total alkalinity levels. Excessively high or low readings exacerbate metal staining.
