How to Lower Ph in Pool With the Help of Adjustable Filters
Pool owners know how to lower PH levels in pool water as part of maintaining its safekeeping. However, the PH level is only one aspect of water quality and a lot depends on factors such as the quality of the soil where the pool is located and the weather. Any chemical addition to the pool, be it sunscreen, bug repellent or leaves from the surrounding trees will greatly alter the pH level. When the water becomes too acidic (towards 7.4) it may cause cloudy water or it may lead to scaling of the pool equipment or the pool itself; something which can be extremely expensive to remedy. On the opposite end of the spectrum, if the pH level in the pool water is too alkaline, it can produce an extremely pleasant environment for swimming.
The first thing you need to do when learning how to lower PH levels in pool water is to check your local water standards. Depending on where you live, you may have specific guidelines or restrictions regarding the PH level of your local water. In any case, check the guidelines with a reputable pool supply company and make sure that your filter or system will meet the guidelines. Failure to comply with these standards can result in fines.
There are many types of filters used to keep water pH levels in check. A popular option is the use of an ion exchange system. This type of filter replaces the use of chlorine by exchanging sulfuric acid with sodium ions in the pool water. A downside of this type of filter is that it requires regular replacement of the sodium beads. Another type of filter, the muriatic system, uses salt instead of chlorine to maintain the pH level in the pool. While this method does not eliminate the threat posed by bacteria, it does reduce the amount of sodium bisulfate that is being used.
The use of an algaecide is another way of managing pH levels in the pool. Commonly used for lawn irrigation, algaecide helps to lower the acidity of pool water. This is accomplished by reducing the amounts of hydrogen sulfide, a chemical substance produced by bacteria, in the pool. Algaecide is best used with the use of an ion exchange system, or when the alkalinity is already stable in the pool.
Adding baking soda to pool water is also a great way of lowering the pH level in your pool. It works by reducing the effectiveness of an unfavorable natural biological compound called aralase. This compound accumulates in the lining of swimming pools, eventually causing the pool to become dirty and cloudy. When adding baking soda to the pool water, you can further reduce the aralase build-up by adding a little bit of chlorine through a floating tablet dispenser. This will kill any leftover bacteria and reduce the amount of dissolved oxygen in the pool water.
If you have problems with too much alkalinity in your pool, or if your pH levels are getting too high, it might be time for a chlorine burnout. A chlorine burnout is when the system in your pool is “surged.” The term “cheap” is used to describe this method, as compared to traditional chlorine purifiers that use more than 2 million pounds of chlorine each year. An automatic system that delivers hot water on demand can provide the same service for less than half the amount of chlorine. With cheap chlorine burnouts, alkalinity can quickly drop below safe levels and your swimming pool may no longer be safe for swimming.
As stated earlier, most experts agree that the best way of dealing with high pH levels in a swimming pool is to first stabilize the alkalinity. Once stabilized, you can then add a source of low pH chemicals. These can come in the form of a simple anti-chlorine bleach product, granular or activated carbon, or a salt solution. While these products do work, keep in mind that there are still other factors to consider before adding them to your pool. It is best to consult an expert or a pool maintenance company before deciding which product or combination of products to use.
While the use of sodium bicarbonate is not specifically recommended, it does work in stabilizing alkalinity and has been found to reduce the surface tension of pool water. However, sodium bicarbonate also tends to produce strong evaporation reactions that cause water evaporation, which in turn lowers the PH level even further. In pool water that experiences high pH levels, you typically see fewer but larger blackflies. And, if you have children in the area who swim often, having a PH reading that is lower than desired can help them enjoy the swimming pool more.
