When it comes to pool maintenance, pH balance is can not be ignored. pH imbalance can cause turbidity in the pool water, decrease the effectiveness of disinfectants, corrode the pool and machinery and so on. Both too low and too high pH levels are the representation of water imbalance. In this article, we will mainly talk about low pH levels.
What is pool pH?
The first thing we need to know is, what is pH? pH is an index that measures the acidity and alkalinity of a solution, usually between 5 and 9 for water. A pH of 7 is neutral; A pH above 7 is alkaline and below 7 is acidic. In order to balance the pool water, pH levels should be maintained at 7.2-7.8, with the optimal range being 7.4-7.6, so that chlorine can effectively kill bacteria. When pH level of the pool water is less than 7.2, the water is considered to be corrosive acid water. Not only can acidic water irritate the eyes and skin, but it can also corrode pool walls, pumps, or other pool machinery.
What causes low pH levels?
The most common factor is rain. After a heavy rain, the rainwater will dilute the pool water, which will lower pH level. Then, holding a pool party can affect pH levels because people will carry sweat or other contaminants into the pool. Additionally, the pH level of a chlorine swimming pool exposed to sunlight will also decrease due to the influence of UV.
How to raise pH in your pool?
You may have heard of baking soda to raise your pH levels. Baking soda, also known as sodium bicarbonate, is actually a chemical used to improve the total alkalinity of the pool water, and has a small impact on pH levels. If there is not enough total alkalinity in your pool, you can use it to increase the total alkalinity.
In general, we often use sodium carbonate as a pH Plus. Sodium carbonate, also soda ash, when added to water, can improve the pH and the total alkalinity of the pool water. Before using it, test the current pH of the pool to determine the correct dosage. Then, after diluting the soda ash in a bucket, slowly pour it into the pool evenly so that it is evenly distributed throughout the pool.
Actually sodium hydroxide (NaOH) can also increase the pH level of the pool water, but does not increase the total alkalinity. It is important to note that NaOH is corrosive, and you must wear a mask, safety goggles and chemical-resistant gloves when handling it.
All in all, maintaining the reasonable pH level can provide a safe and healthy swimming environment for swimmers. If you need pH Regulator, please feel free to contact us.
