Best Pool Shock Essentials Reviews – Top Ingredients and Chemicals (2020)

A swimming pool is a great way to have fun and exercise. Many people build a swimming pool and enjoy the initial weeks. However, with time, a swimming pool requires maintenance. It can be challenging to maintain the pool. Usually, bacteria and algae grow in a swimming pool. This can lead to skin irritation and other skin diseases. However, this can be solved by treating the water with chlorine. This method is also known as chlorination.

Though chlorination is an effective way to treat a pool, there are instances where it is not. It has been observed that chlorination is not always effective in pools which have been treated many times. It is because the bacteria and algae get used to the amount of chlorine. Hence, there is a need to surprise the bacteria and algae present. To do this, pool shocks were introduced. The basic principle of pool shocks is to suddenly increase the amount of chlorine by four to five times. This sudden increase leads to the neutralization of all harmful bacteria in the swimming pool.

Not every pool shock has the same effect. Some pool shocks outclass the others by a huge margin. However, without proper guidance and knowledge, you may not be able to find the best pool shock. Therefore, through our research, we made a list of the best pool shocks on the market at present.

Best Buying Guide for Pool Shock

How fast do the best pool shock ingredients dissolve?

The dissolving rate of pool shock is an essential factor. It is recommended to dissolve the pool shock in a bucket before pouring it into the pool. Hence, the faster the dissolving rate, the faster you can drain the shock into the pool. There are a few pool shock solutions that offer a quick-dissolving rate. Hence, you need to be careful while choosing.

What is the best PH level you should maintain after the pool shock?

There are two conditions you can face due to the change in the PH levels in the pool. Either it will become salty, which will lead to corrosion, or it will become highly acidic, which can lead to skin irritation. Hence, we recommend you select a pool shock that can maintain the PH between 7.2 to 7.6. If a pool shock is not offering PH balance, then it might not be the right choice for you.

Choose the best pool shock chemicals and ingredients

There are two categories of pool shock, granular and liquid. Though both shocks are valid, a granular shock is considered a little more practical than the liquid ones. It is also observed that the granular ones are easier to store. Go for the high-quality ones to make your purchase worthwhile.

Does the best pool shock need to be stabilized?

Many people are unaware of the fact that stabilized shock is far better than unstabilized ones. Hence, it is recommended to select the shocks that have stabilized chlorine levels.

Is the best pool shock affordable?

This is a misconception that the best pool shock costs more. Many companies in the market are offering high-quality shock at affordable prices. Hence, it is recommended to focus on the best pool shock that falls within your budget.

Frequently Asked Questions

Are chlorine and shock the same thing?

No, these two are not the same thing. They have a vast difference between them. Chlorine is generally used to treat water and clear impurities. Especially the pollutants like bacteria and algae that can cause skin irritation. Hence, chlorine is like a purifier for your pool.

On the other hand, when you shock your pool, you suddenly increase the content of chlorine in it. It also helps to maintain the PH balance and disinfect if it has calcium hypochlorite as an ingredient. There are shocks on the market that can even reduce the odor of chlorine in the pool. Hence, the shock has diverse effects and uses, while chlorine is explicitly used to treat impurities.

Is HTH pool shock pleasant?

The answer to this question depends on your requirements. Are you looking for a shock that needs to be added once a week? Then, yes, HTH pool shock is a great deal. They are the high-intensity versions of the regular shocks and super effective against algae and bacteria. However, you have to be extremely careful with this shock. If overused in the pool, it can lead to damage to the pool. Therefore, if you are planning to use it, follow the instructions exactly.

What is the difference between shock and super shock?

The primary difference between the two is concentration. Regular shocks contain 68% calcium hypochlorite, which makes them moderately effective against algae and bacteria. However, super shock contains more than 73% calcium hypochlorite. Hence, they are more efficient in killing bacteria and algae. Another difference is stability; shocks are unstable. Thus, they require more time to react in the pool. However, a super shock is stable, which leads to a faster reaction against algae and bacteria.

Despite these, a super shock can damage your pool, if not used with precautions.

What is the best shock to use in my pool?

There are three categories of shock. Cal-Hypo, Sodium-Di Chlor, and Pottasium Mono. Though each of these has its own merits and demerits. However, through our research and experience, we came to know that the Calcium-Hypo shocks are the most effective ones. They have the perfect chemical properties to eliminate impurities like bacteria and algae. Hence, Cal-Hypo is the best pool shock choice. They have the least side-effects when overused and the most benefits.
