Your Pool's Water Chemistry
Pattaya Pool Water Chemistry: Your Guide to a Healthy, Balanced Pool
The importance of Water Chemistry balance when maintaining a swimming pool in warm, humid climates like Pattaya & Jomtien region is greatly accentuated...
Understanding Key Pool Water Parameters (pH, Chlorine, Alkalinity)
In tropical regions like Chonburi, Pattaya, and Jomtien, Thailand where warm temperatures and high humidity persist year-round, swimming pools provide a much-needed respite from the heat. However, maintaining a pool in these climates requires more vigilance and expertise compared to cooler regions and climates. The high consumption rates of chlorine and much stronger UV from the sun in such warm conditions demand a careful balance of water chemistry. Mismanagement of these factors, especially through over-chlorination, can lead to serious health risks and damage to the pool, its equipment, surroundings and its infrastructure.
Why Balancing Pool Water Chemistry Is Crucial
In warmer, humid climates, the rate of chlorine consumption is significantly higher. This is due to factors such as increased pool usage, higher temperatures that accelerate the disintegration of the HOCL and evaporation of the chlorine ions, along with much faster organic contamination from the local environment.
The instinct to "solve" this by overdosing chlorine often backfires, creating higher levels of the hazardous by-products like chloramines and trihalomethanes (THMs). Chloramines form when chlorine binds with ammonia from organic matter like sweat urine and cosmetic skin and hair products people use.
These compounds not only give off a strong "chlorine" odor but also cause eye irritation and respiratory problems, and sustained contact can lead to considerable health risks.
Trihalomethanes (THMs), are a category of disinfection by-products (DBPs) and are linked to more severe health risks, including cancer, liver damage, and kidney issues. Excessive chlorine dosing disrupts the delicate balance required to keep pools safe and clean, emphasizing the need for precise water chemistry management, particularly in hotter, more tropical climates [6].

Key Aspects of Pool Water Chemistry
To maintain a pool in regions like Chonburi and Pattaya, frequent monitoring of three key aspects is critical: pH levels, chlorine levels, and total alkalinity. In the tropical heat, pool water pH tends to rise rapidly, making it essential to keep the pH within the ideal range of 7.2-7.8.
This ensures that the chlorine can effectively disinfect the water while avoiding skin irritation and equipment damage [4].
Total alkalinity acts as a buffer for pH, stabilizing the water's overall balance. Maintaining alkalinity between 80-120 ppm helps prevent rapid fluctuations in pH, which can lead to inefficient chlorine usage and corrosion of pool surfaces.

Saltwater Pools and the Challenge of Over-Chlorination
Many people in Thailand opt for saltwater chlorinated pools due to their ease of use and other perceived benefits such as lower chlorine levels. While saltwater systems reduce the need for adding chlorine manually, they still rely on generating chlorine through a salt-chlorine generator, which ionizes the Sodium and Chloride in salt into Chlorine Gas, which is fed into the water system in the pump room.
In tropical climates, much higher consumption rates tend apply to saltwater systems because of the harsher UV from the sun and obviously much higher year round water temperatures, which often sees pool owners 'topping up' their automated salt water pools with old fashioned granular or powdered TCCA chlorine.
Misunderstanding here can still result in the same dangerous by-products such as chloramines and THMs [3] however in much higher more dangerous levels than even the old manual methods. This is primarily because of 2 factors:
1. The salt systems were actually originally (1960s-70s) designed for cooler western climates and certainly NOT designed for ad-hock bombing of the system periodically with shock doses of TCCA chlorine.
2. In such cases, the Total Alkalinity (TA) drops rapidly like an avalanche and often takes the pH and all water chemistry with it, causing a very negative acidicly & an imbalanced mess. Oh the water might look clear... but its actually a set of bigger problems compounding upon each other. [9].

Introducing BioPools: A Safer, Sustainable Alternative to Chlorine
A novel technology known as Biopools has been developed to address the challenges associated with traditional chlorine and saltwater chlorination in swimming pools in hot climates. Biopools employs an innovative combination of hydrogen peroxide (H₂O₂) and a biopolymer stabilizer to maintain water sanitation and cleanliness, eliminating the need for harsh toxic chemicals such as chlorine. This approach prevents the formation of hazardous by-products, including trihalomethanes (THMs) and chloramines, which are common carcinogens and irritants produced in conventional chlorine based systems.
Biopools offer significant advantages over the older systems that do not rely on poisons like chlorine at all and maintain stable water chemistry even under high-stress conditions, such as increased bather loads or heavy rainfall—situations typical of tropical climates like those here in Thailand.
Conclusions
In the warm, humid climate of Thailand's coastal regions, pool maintenance requires precise attention to water chemistry. Mismanagement, particularly through over-chlorination, can lead to health hazards due to the formation of chloramines and trihalomethanes. It can also lead to much higher rates of corrosion on pool surfaces equipment and surroundings, due to the very highly corrosive nature of chlorine and its associated elements and chemicals.
Regular testing and balancing of pH, chlorine, and total alkalinity are essential to avoid these risks. The introduction of Biopools offers a promising, safer, and more sustainable solution, providing clean and balanced water without the drawbacks of traditional chlorine-based systems and without adding damage to our planet’s struggling atmosphere.
