Revealed: Why is My Pool Water Cloudy after Shocking?
For new pool owners who have just shocked their pool, they often ask that “why is my pool water cloudy after shocking?”. While time is also a priority, clearing a cloudy pool would require the expenditure of money.
Moreover, if you aren’t a fan of a clear pool, health reasons might also change your outlook. In addition to the usual ramifications, people have also reported eye discomfort, an eyesore and short filter cycles resulting from a cloudy pool.
Thus, if you’re going to a public pool, make sure that it is clean. Otherwise, if the pool is cloudy, don’t jump into it. This might cost you a bit of excitement, but your health will remain safe.
Why is My Pool Water Cloudy after Shocking?
There could be many reasons for a cloudy pool. However, when it comes to shocking, the main reasons are listed below. Moreover, in addition to giving you the reasons, we have also included remedies to solve your problem.
The first reason –the most common cause of a cloudy pool water, is the imbalanced concentration of pool chemicals. When added in an adequate amount, they will maintain the pH, alkalinity, and chlorine levels of the pool. However, if the concentration is imbalanced, they will give your pool a cloudy appearance.
Therefore, in order to prevent this from happening, properly maintain the chemistry of your swimming pool water.
Problems with the filter
Most people have a misconception that only shocking the pool would make it clear. While it is a step in clearing the water, pool shocking is not the whole process. In simple words, shocking the pool water won’t do the whole job for you.
You’ll have to filter the water as well. If the filter is not working properly, the pool water will turn cloudy. Hence, the proper functioning of the filter is crucial to maintaining a clean pool water.
For example, if you have a sand filter, the cloudy appearance won’t go away for a week. As a result, if you have a sand filter installed in your pool, all you can do is wait. Or, if you have the willpower, you could replace the sand in the filter as well. This should solve your problem.
In the case of a cartridge filter, pool water will turn cloudy if the cartridge is not in good working condition. In this case, you’ll have no choice but to replace the cartridge. However, the problem can also arise when you have just replaced the cartridge.
This usually happens when the filtering rate exceeds the upper limit of the filter. As you might guess, the cartridge filter has an upper working limit. Go above that limit and the filter will malfunction. Consequently, cloudy pool water will follow soon.
Lastly, for a DE filter, there could be a myriad of reasons for a cloudy pool water. The two most common ones are the absence of backwashing of the filter and the lack of washing of the DE.
However, if you think that your filter doesn’t have any of these two problems, you need to consult a specialist as it may be defective. In this case, your filter will need a repair to start working effectively once again.
High levels of Calcium
There was a time when chlorine was the universal leader in pool shocking chemicals. However, due to the dangers associated with its usage, that time is long gone now. Chlorine often decreases the pH level of the pool, thereby aggravating the formation of algae.
This algae, once fully formed, could turn your pool water green and/or cloudy. Hence, the use of chlorine as a shocking chemical was reduced.
Since most people use calcium hypochlorite now, the major reason for a cloudy pool water is high levels of calcium. With the high levels of calcium, your pool water will become hard.
This usually happens when the calcium levels of your pool exceed 220ppm. Thus, if you want to prevent this from happening, maintain the calcium levels in the optimum range of 180-220ppm.
High Level of Cyanuric Acid
Another reason for a cloudy pool after shocking is the high level of Cyanuric Acid. While it is added to water in dissolved form, the solubility of cyanuric acid in water isn’t very high. As a result, sometimes it can come out of solution. This usually happens when its levels go above 50ppm.
High alkalinity is yet another reason for a cloudy pool water. In case the chemicals have made water highly alkaline, it will start to throw off bicarbonates in powder form. These bicarbonates will then come on the surface of the water to make it cloudy.
In case you are searching for a remedy, I would recommend you to go for a pool clarifier. Most pools get cloudy due to the tiny particles of bicarbonates which appear on their surface. Since these particles have low density, they won’t easily settle down.
Consequently, it becomes nearly impossible for the filter to entrap these particles. A pool clarifier sorts out this problem by binding these particles. Once bonded, they will go down due to their own weight. As a result, the filter will entrap them easily.
It is not possible for anyone to assure that your pool water won’t turn cloudy. However, if you don’t live in an adverse weather area, make sure that your “efforts” don’t make the water cloudy. When mistakes happen, the above-mentioned tips should help you.
