Maintaining the health and clarity of your swimming pool requires a solid understanding of its water chemistry. At Ningbo Inno Pharmchem Co., Ltd., we believe that informed pool owners are happy pool owners. This guide focuses on the crucial aspects of pH, total alkalinity, and calcium hardness – the key water balancers that ensure your pool is not only safe and inviting but also protected from damage.

The Significance of pH Balance

pH is a measure of how acidic or alkaline your pool water is, on a scale of 0 to 14. A perfectly balanced pH level for a swimming pool is between 7.4 and 7.6. Why is this range so important? When pH is too low (acidic), it can cause eye and skin irritation, damage metal pool components through corrosion, and degrade pool surfaces. Conversely, when pH is too high (alkaline), it can lead to cloudy water, scaling on pool surfaces and equipment, and reduced effectiveness of your sanitizer. You can adjust pH using 'pH Up' (like soda ash) to increase it, or 'pH Down' (like muriatic acid or sodium bisulfate) to lower it.

The Role of Total Alkalinity (TA)

Total Alkalinity is often referred to as the 'pH buffer.' It works to stabilize your pool's pH, preventing it from fluctuating wildly due to external factors like rain or chemical additions. Recommended TA levels typically fall between 80 to 120 parts per million (ppm). If your TA is too low, your pH will become unstable, making it difficult to maintain. If TA is too high, it can cause scaling and cloudy water. You can raise TA using an alkalinity increaser, such as sodium bicarbonate (baking soda).

Calcium Hardness: Protecting Your Pool's Integrity

Calcium Hardness (CH) measures the amount of dissolved calcium in your pool water. Maintaining the correct CH level, generally between 200 to 400 ppm, is vital for protecting your pool's surfaces and equipment. If the water is too 'soft' (low calcium hardness), it will aggressively try to absorb calcium from surrounding surfaces, leading to etching of plaster, grout deterioration, and damage to vinyl liners and equipment. If the water is too 'hard' (high calcium hardness), it can cause cloudy water and calcium scaling on surfaces and in pipes. Calcium chloride is typically used as a calcium hardness increaser.
