Proper pool water chemistry creates a safe, enjoyable swimming environment and protects the longevity of your pool. Pool water chemistry involves balancing physical, chemical and biological factors to achieve clean, clear water while protecting your pool’s surfaces and equipment. Whether you’re a seasoned pool owner or new to the pool maintenance process, understanding the principles of pool water chemistry can help you avoid common mistakes and maximize your pool’s performance.
Let’s look at the key components of pool water chemistry, its benefits, and tips for maintaining the perfect balance.
Key Components of Pool Water Chemistry
Understanding the core elements of pool water chemistry helps you maintain a safe and efficient pool environment.
pH Levels
You’ve probably heard of this one — pH measures the acidity or alkalinity of your pool water. A balanced pH (7.4–7.6) protects swimmers’ skin and eyes while preventing damage to pool equipment and surfaces.
2. Chlorine and Sanitizers
Chlorine is a vital sanitizer that eliminates harmful microorganisms. Maintaining chlorine levels between 1 and 3 ppm ensures water safety without overexposure to chemicals.
3. Alkalinity
Total alkalinity buffers pH levels, preventing fluctuations that can lead to corrosion or scaling. The ideal range is 80–120 ppm.
4. Calcium Hardness
Calcium levels (200–400 ppm) are crucial for preventing scaling and etching, which can harm pool surfaces and equipment.
5. Cyanuric Acid (CYA)
This stabilizer helps chlorine last longer by shielding it from sunlight. However, excess levels can reduce chlorine’s effectiveness. Aim for 30–50 ppm.
6. Other Components
Additional factors such as phosphates, metals and total dissolved solids (TDS) should also be monitored to maintain ideal water quality.
At Watermark Pools & Outdoor Living, we use the advanced Orenda LSI Calculator to ensure water balance based on the Langelier Saturation Index (LSI). This modern approach to pool maintenance avoids outdated industry standards, preventing issues like scaling, staining and corrosion while maintaining long-term water quality.

Benefits of Proper Pool Water Chemistry
Maintaining balanced pool water chemistry offers numerous advantages.
Health and Safety
Balanced water reduces the risk of skin irritation, respiratory issues and illnesses caused by harmful bacteria and algae. Proper sanitization creates a safe swimming experience for everyone.
Pool Longevity
Proper water chemistry protects your pool’s surfaces, plumbing and equipment from damage caused by scaling, corrosion or staining. This extends the lifespan of your pool and reduces costly repairs.
Aesthetic Appeal
Well-maintained water is clear and free of algae blooms, foul odors and discoloration, creating a more inviting environment for swimmers.
Cost Savings
Balanced water reduces the need for frequent chemical adjustments, prevents expensive damage and improves the efficiency of your filtration and heating systems, saving money over time.
Tips for Maintaining Pool Water Chemistry
Keeping your pool water balanced requires consistent pool monitoring and proactive care.
1. Regular Testing and Monitoring
For heated pools, use reliable water testing kits to test the water at least once or twice weekly. Also, check the pH, chlorine, alkalinity, calcium hardness, and CYA levels regularly.
2. Accurate Chemical Dosing
Use the LSI Calculator to determine precise chemical dosages. Avoid guesswork and always wear protective gear when handling pool chemicals.
Additionally, enzymes are key in breaking down oils, lotions and other non-living organic materials. Enzymes are not one-size-fits-all solutions, so it’s important to use them tailored to your pool’s specific needs.
3. Professional Pool Maintenance
Scheduling regular inspections with Watermark ensures issues are detected early, preventing more significant problems down the line.
4. Minimize Swimmers’ Impacts
People introduce new chemicals into the pool ecosystem, too. Disinfection chemicals are necessary for killing pathogens, but at the same time, they can create other issues. Many of them react with organic material in the water like dirt, sweat, urine, and even skin moisturizers—to form disinfection by-products (DBPs). That’s why it’s important to be aware of healthy pool hygiene and encourage swimmers to rinse off before they get in the pool. While sunscreen is usually a must-have, ideally, swimmers will rinse off before entering the pool and before applying sunscreen.
To minimize the impact on pool chemicals, look for sunscreens labeled "pool friendly" or "reef safe." These typically contain zinc oxide and titanium dioxide as active ingredients, meaning they are mineral-based rather than chemical-based. Avoid sunscreens containing ingredients like octocrylene or phenoxyethanol.
