Three Essential Steps to Creating a Healthy Pool: Sanitation, Shocking, and Prevention

Table of Contents

During the summer, a swimming pool is an excellent place for entertainment, relaxation, and exercise. However, maintaining a pool is crucial to ensure it remains clean, safe, and aesthetically pleasing. Proper pool maintenance doesn’t have to be complicated. Besides regular water testing and balancing, pool cleaning, and ensuring adequate circulation and filtration, pool owners must understand the importance of keeping the water free of bacteria and algae through three simple steps: sanitation, shocking, and prevention. This article will detail these steps and provide additional tips for maintaining a healthy pool.

Three Essential Steps to Creating a Healthy Pool: Sanitation, Shocking, and Prevention
Maintaining a clean, safe, and aesthetically pleasing pool requires diligent regular maintenance, including daily sanitation, weekly shocking, and preventing algae growth by removing phosphates.

Step 1: Daily Sanitation to Ensure Healthy Pool Water

Importance of Sanitation

Sanitizing pool water is the primary task in maintaining water quality. Effective sanitation eliminates bacteria, viruses, and other harmful microorganisms that can cause illness and infection, ensuring the safety of swimmers. Pool chlorine tablets are one of the most common and effective methods for daily sanitation.

Using Pool Chlorine Tablets

Pool chlorine tablets are typically stabilized trichlor tablets that dissolve slowly in water, maintaining a consistent level of free available chlorine. This is crucial for controlling bacteria and algae in the pool. Trichlor tablets contain a stabilizer called cyanuric acid, which prevents chlorine from breaking down under strong sunlight.

Water Quality Testing and Chlorine Levels

Regularly test the water quality—at least once or twice a week. Maintain a free available chlorine level between 1-4 ppm to ensure water safety. If the chlorine level is consistently low, increase the daily sanitizer dosage. Low chlorine levels may also indicate a higher chlorine demand, necessitating further treatment.

Alternative Sanitization Methods

In addition to pool chlorine tablets, alternative methods such as mineral systems and saltwater chlorinators can help reduce the number of chlorine tablets needed and enhance sanitization effectiveness.

Step 2: Weekly Pool Shocking

Importance of Shocking

Despite maintaining proper chlorine levels, organic contaminants and chloramines can accumulate, causing cloudy water, skin and eye irritation, and a strong chlorine odor. Weekly pool shocking effectively removes these contaminants and harmful organisms, ensuring a healthy and sanitary pool.

Choosing the Right Shock Treatment

Select the appropriate shock treatment based on the pool’s condition. For severe contamination or low chlorine levels (below 2 ppm), chlorine shock is most effective. For routine maintenance with free chlorine levels of 2 ppm or higher, non-chlorine oxidizing shock can effectively break down non-living organic contaminants and prevent chloramine formation. Additionally, non-chlorine shock allows swimming within 15 minutes after use.

Optimal Time for Shocking

Shocking the pool at night is generally most effective, as it prevents chlorine from breaking down in sunlight and allows ample time for it to work. Nighttime shocking also ensures chlorine levels return to normal before swimmers use the pool again.

Step 3: Preventing Algae by Removing Phosphates

Algae Problems and Prevention

Algae growth is a common issue in pools. Green, algae-infested water is unsightly and indicates improper water balance, circulation, or sanitation. Algae thrive in warm, moist environments and can quickly grow in unbalanced or inadequately sanitized pool water, even in well-maintained pools.

Using Phosphate Removers

Phosphates are a primary food source for algae and can enter the pool from plant debris, soil, cosmetics, and more. Using phosphate removers eliminates phosphates from the water, preventing algae growth. Calcium hypochlorite and enzyme products also effectively reduce chlorine demand and maintain clear water.

Preventive Maintenance

Regular use of enzyme and phosphate remover products can prevent algae growth, reduce chlorine usage, save water, and maintain water clarity.

Additional Tips for Maintaining a Healthy Pool

Cleaning the Pool

Regularly remove debris from the water surface and pool bottom, brush all pool surfaces, and manually vacuum as needed. This helps maintain chlorine effectiveness and prevent organic stains and algae problems. Automatic pool cleaners can save time and effort.

Testing and Balancing Water Quality

Test the water quality at least once a week to ensure balanced chemical levels. Adjust any imbalances promptly using water balancers. Use home test kits for basic monitoring and take water samples to professional centers for detailed analysis and customized treatment plans.

Circulating and Filtering Water

Run the filtration pump daily for sufficient time, typically 8-10 hours, to filter all pool water. Increase filtration time during high usage or high temperatures. Regularly check the filter pressure gauge and clean the filter when the pressure rises 8-10 psi above the starting “clean” pressure.

Emptying Baskets

Regularly check and empty the pump and skimmer baskets to remove debris, ensure proper water flow, and prevent equipment blockages. Replace broken or damaged baskets as needed.


Following these steps and using the right products can ensure a fun, relaxing, and exercise-filled swimming season in a healthy, algae-free pool. If you have any questions or encounter any issues, consult professionals to ensure effective and safe pool maintenance.
