An important part of pool maintenance is checking and balancing the water chemistry. Proper levels of pH, alkalinity, chlorine, cyanauric acid, among others are critical elements of water chemistry. The water chemistry needs to be checked and balanced, as required, on a weekly basis. ASP technicians receive training specific to water chemistry balancing. Proper water chemistry balance improves the appearance of your pool and provides a pool that is safe to use.
Determining how acidic or how “basic” the water in your pool is is determined by measuring the water’s pH level. Even though the pH level of your swimming pool water may range between 6.6 and 8.4, a neutral balance between 7.4 and 7.6 is the desired target. The lower the pH level, the more acidic the water and the higher the pH level, the more “basic” the water.
Acidic swimming pool water or “hungry water” can be defined as water with a pH level lower than 7.4. Acidic water will attempt to raise its pH level to the neutral range by pulling elements from pool materials through corrosion.
“Basic swimming pool water or “over saturated” water can be defined as water with a pH level greater than 7.6. “Basic” water will attempt to attain a neutral pH level by depositing elements from the pool water causing an increase in the buildup of scale and other harmful minerals.
Total alkalinity is a measurement of the alkaline content of your swimming pool water and is affected by the pH level of the pool water. Low alkaline levels result in constant, rapid fluctuations in the pH level of the pool water. High alkaline levels result in cloudy water or undesirable water clarity.
Calcium hardness is a measurement of the quantity of calcium present in your swimming pool water. Pool water with low calcium hardness will seek to obtain calcium available from pool materials resulting in damage to pool tiles and plaster finish. Pool water with high calcium content is cloudy with undesirable water clarity. In order to improve water clarity and to avoid damage to pool tiles and the plaster finish, calcium hardness needs to be properly balanced.
Cleaning the Pool
Each week your pool will be cleaned by a certified ASP technician. Removal of unwanted debris and other materials that should not be present in your pool will be removed. Larger debris will be removed from your swimming pool using a Leaf-Master when required. Surface debris about the pool will be removed and the surface area will be swept. In order to prevent the build-up of algae and grime, the surface tiles will be scrubbed.
Proper Filtration and Water Flow
The flow of water throughout the pool has a major impact on the appearance as well as the “health” of the pool. The swimming pool pump filter is considered the “heart” of the swimming pool. All chemicals present in the pool water are pumped to all areas of the swimming pool, including through all the pool pipes, by the pool filtration system. In order to insure proper operation and function, the filtration system is completely checked by your ASP technician. Inadequate water flow by the pool filtration system can result in the presence of algae, calcium build-up and equipment and pool corrosion.
Consider a Salt Water System
A traditional swimming pool chlorination system requires the addition of chlorine, in some form, to the pool filtration system. The chlorine enters the pool water, is consumed, and additional chlorine is required to be added. Salt water chlorination systems involve a process where salt is converted to chlorine which is converted back to salt and the process begins again. Salt water chlorination systems require less maintenance since the chlorination process essentially takes care of itself. An additional benefit is that the chlorine level in the pool is more stable. Although salt water chlorination systems are not as common as the traditional chlorination methods, benefits include less time to balance the pool chemistry and less damage and irritation occur to skin, eyes, and hair.
