What Is Pool Chemistry?

Pool owners often believe that if they brush their pools regularly and run the pump as directed by the manufacturer, their pool will stay sparkling clear and inviting.  Chemistry is boring! Soon, the pool water becomes cloudy and no one wants to swim or play in the pool.

The fact is, water chemistry is a crucial aspect of pool maintenance, and failing to keep it in balance can lead to various problems for the pool and swimmers. Here are some of the intricacies of water chemistry and the potential issues that can arise when it's not properly maintained:

pH Level‍

The pH level of pool water is a measure of its acidity or alkalinity. If the pH level is too low (acidic) or too high(alkaline), it can lead to several problems:

• ‍Low pH: Can cause corrosion of pool equipment, irritation to swimmers' skin and eyes, and can damage the pool's surface.‍
• High pH: Can result in cloudy water, reduced effectiveness of chlorine, and also lead to skin and eye irritation.

Chlorine Levels‍

Chlorine is used to disinfect pool water and kill harmful bacteria and algae. If the chlorine level is not properly maintained, it can lead to various issues:‍

• ‍Low Chlorine: Can result in poor water sanitation, allowing harmful microorganisms to thrive, leading to green or cloudy water, and potentially causing illnesses among swimmers.‍
• ‍High Chlorine: Can irritate swimmers' skin and eyes, damage pool surfaces, and create an unpleasant chemical odor.

Alkalinity‍

Alkalinity acts as a buffer to help stabilize the pH level. Improper alkalinity levels can make it difficult to maintain a consistent pH, leading to pH swings and associated problems.

Calcium Hardness‍

This measures the amount of calcium in the water. Low calcium hardness can lead to pool water becoming corrosive and can cause damage to pool surfaces and equipment. High calcium hardness can result in scaling and cloudy water.

Total Dissolved Solids (TDS)‍

TDS is a measure of the total amount of dissolved materials in the water, including minerals and impurities. High TDS levels can make it difficult to maintain water chemistry, leading to cloudy water and other issues.

Cyanuric Acid (CYA)‍

CYA is a stabilizer for chlorine, helping it remain effective in sunlight. However, excessive CYA levels can lead to chlorine becoming less effective, potentially resulting in poor water quality and algae growth.

Failure to keep these aspects of water chemistry in balance can result in a range of problems, including:

• ‍Algae growth
• Cloudy or discolored water
• Scale buildup on pool services
• Corrosion of pool equipment
• Skin and eye irritation for swimmers
• Increased risk of waterborne illnesses

To avoid these issues and ensure that the pool water is safe and enjoyable for swimmers, regular water testing and chemical adjustments are necessary. This is where the expertise of professional pool cleaners comes into play, as they can accurately assess and maintain water chemistry, keeping the pool in optimal condition.
