Why is My Pool Still Cloudy After Shocking?

pool still cloudy after shocking

Today, we’d look at a rather common question found around lots of pool owners and managers across the globe. Why does my pool still get cloudy after shocking it? A cloudy pool can only be managed appropriately when the direct causes of the cloudiness are treated. In most cases, this is caused by an imbalance in the various elements present in the pool. Even when we can agree that the majority of a pool’s composition is water, other chemicals are present also.

So for folks who are not familiar with the term “shocking,” it is simply a phenomenon that involves the addition of chemicals to decontaminate bacteria. These chemicals are often categorized in chlorine and non-chlorine chemicals. Because well, a large amount of chlorine is needed in your pool water anyway. So, the addition of chlorine and non-chlorine disinfectants is called Shocking. Meanwhile, the color sometimes doesn’t change after shocking; why?

Swimming in a cloudy pool could attract a few waterborne pathogens to one’s skin. It would be in everyone’s best interest to avoid such unfortunate instances of individuals having these skin irritation. Constant shocking and cleaning a cloudy pool goes beyond having a blue attractive swimming pool. It’s more healthy to shock and clean now and then. Stay with me as we begin to look into various causes behind pools getting cloudy and ways to clear them.

Inadequate Amount Of Free Chlorine

Low free Chlorine level, among other free chemicals, is one of the major reasons behind a cloudy pool. A reduction in the minimal quantity of free chlorine results in the increased formation of chloramine. This chemical is popularly known as “Combined Chlorine,” and it’s often single-handedly known to cause pool clouding. When you notice a cloudy pool, check for the free chlorine level, match it up with the chlorine level, and then check the presence of chloramine. So in your quest to ask why is my pool still cloudy after shocking it, check for the level of these chemicals.

Presence Of Ammonia

One other pointer to why your swimming pool could get cloudy is level irregularities in chemical readings. When taking your chemical readings, and you notice a sudden spike in the CC levels and an increased need always to add chlorine, something’s up. Or perhaps you also noticed a ridiculous drop in the Cyanuric level approaching zero, then you’ve got an issue. In most cases, these signals point towards the presence of ammonia in your pool. If this is confirmed, the best way to get rid of the chemical is by averaging it up with chlorine.

Faulty Filter

As we know, bad or faulty filtration in the pool system leads to a couple of things which pool cloudiness is a part of. It only makes sense that if the filtration basket is no cleaned out or emptied now and then would lead to a pile of dirt being stored. When this happens continuously, the basket loses the grip of filtering these particles from the pool. Always check if the filter cartridges are in good condition when your pool gets cloudy. Also, poor scaling on the filter would most likely lead to the inadequate circulation of water. This eventually leads to dust and tiny particles getting stuck on the pool, which could cause cloudiness in the long run.

Environmental Particles And Dust Accumulation

People get too anxious to make a big deal out of an issue while ignoring the potential cause around them. In the course of answering the question, why is my pool still cloudy after shocking it? We’ve gotten to realize that people ignore environmental particles and dust and look forward to other seemingly major causes.

However, if you speak to a man without prior knowledge of pool chemicals, he’d tell you to clear the dust and particles in the pool. Leaves, pollen, stones, and other things can be accumulated on the surface of the pool to affect the coloration of the water. Also, environmental factors like water from an unwanted source attract nitrates and various chemicals that could cause your pool to cloudy. So before being too quick to look so far, check out these things.

High Calcium In The Pool

Excess calcium in the pool water would react with the water molecules resulting in a reaction with a cloudy effect on your pool. Also, the scaling of calcium in the pool causes inactive filtration, which in recent times leads to pool cloudiness.

Before a few decades, pool managers and owners have struggled with the way to eliminate and reduce the level of calcium present in the pool. Mainly because of its hardness on the water and the cloudiness it attracts. But nowadays, the calcium hardness level can be reduced by draining and refilling the pool water.
