Alkalinity<\/strong><\/h2>\n

Alkalinity refers to the pool water's ability to resist pH changes. The main purpose of alkalinity is to help control the pH in the pool. This is because it acts as a regulator so that when elements are added to the pool that would cause a change in pH, this does not happen and thus the pool water is kept in balance.<\/p>\n

When a substance is added to the pool water that can affect the pH, the alkalinity neutralizes it and thus helps maintain the pH within the desired range. Alkalinity is not responsible for what the pH value will be but functions as a buffer helping to keep it at the levels we have chosen.<\/p>\n

One way to check the alkalinity is to use the corresponding test kit. Alkalinity is good to keep within 80-120 ppm. When the alkalinity drops below the lower limit then the water can become very aggressive and the pH can go up and down repeatedly. If the value is higher than 120 ppm the water may become cloudy, salts may form and the pH may deviate upwards.<\/p>\n

To limit alkalinity it is best to add small amounts of acid, either in liquid or dry form, over several days rather than adding large amounts in a short period of time. By adding too much acid, it lowers the pH enough to cause corrosion of pool surfaces and equipment. To increase the alkalinity we can add the appropriate amount of the corresponding chemical in doses that are placed in the water circulation system every few hours. In this case, the water may become a little cloudy.<\/p>\n

Sometimes especially in freshly filled pools it is possible that both alkalinity and pH need adjustment. Theoretically, if one indicator is high or low, the same will happen correspondingly with the other. However, it is not unusual for the reverse to happen. In this case the wrong setting can cause significant problems such as equipment corrosion or calcium precipitation. If this happens it may be worth waiting 24 hours before adding a new chemical. This waiting will result in the natural equilibration of the water without the addition of chemicals, as it allows the water to naturally come into balance. However, if after the end of the twenty-four hours the pool water needs additional care, less time and fewer chemicals will certainly be required.<\/p>\n

If the pH happens to be low and the alkalinity high, first raise the pH to normal and then lower the alkalinity value. When alkalinity is low and pH fine, raise alkalinity first and then lower pH.<\/p>\n

In any case never add acid to the pool water if the pH is lower than 7.2 even if the alkalinity is high. Instead expect it to increase when adding chemical. If the pH does not rise on its own after a day or two you will need to add some pH Up.<\/p>","protected":false},"excerpt":{"rendered":"
