Pool water can undergo color changes for various reasons, some harmless, while others can become troublesome if left unattended. Closely tied to the pool water’s health is its pH level, a critical aspect of water quality for pool owners to monitor consistently.
Pool owners must understand how pH levels affect water appearance and why it’s vital for pool health. If the pH level strays too high, you may need to lower it to the ideal range of 7.2 to 7.8 for optimal pool water health. This proactive approach empowers you to detect and address potential issues in their early stages, preventing them from developing into more significant concerns.
If you’re curious about the reasons behind your pool water’s appearance, this article will provide you with the answers you’re looking for.
Common Pool Water Colors
- Light Blue
A light or medium blue pool water color is typically nothing to worry about. A white pool finish creates a serene light blue shade providing a calming and reflective outdoor ambiance. Traditional blue tones result from a blend of white cement, aggregates, and blue pigments or from azure glass tiling, ensuring a vibrant and uniform blue tint.
Green pool water signals the presence of copper, a result of copper oxidation in chlorinated water. While minor copper levels are normal, elevated concentrations can pose risks. When you observe a green hue, arrange for a thorough cleaning and investigate the source of copper.
Another reason could be the high pH levels that make chlorine less effective at sanitizing the water. This can lead to inadequate disinfection, allowing algae and bacteria to flourish. Algae growth, in particular, can cause the water to turn green or cloudy. When this happens, immediately call professional help to lower the pH level in your pool.
- Brown Water
Brown pool water signifies the presence of iron, which rusts and imparts that orangish-brown hue. Extremely high or low pH levels can also influence the solubility of minerals and metals in the water.
For example, when pH is too low (acidic), it can lead to the corrosion of pool equipment and leach metals like copper or iron into the water. Iron can stain pool surfaces, and equipment, and even affect swimmers’ nails and hair.
- Black Water
If your pool water darkens, it likely contains silver. Like silver tarnishes, chlorinated water oxidizes silver, turning the water black. Black water poses health risks and structural damage to the pool.
- Purple Water
The introduction of chlorine to pool water containing magnesium or manganese can result in a purple hue. Manganese may lead to staining in and around the pool, often remaining hidden until chlorine is added.
