There are three different types of pool shock chemicals on the market – calcium hypochlorite, potassium mono persulfate, and sodium di-chlor. They are all available in granular form or liquid form.
1. Calcium Hypochlorite
This is the most reliable and popular shock. Its upsides are dissolving quickly, and burning off with the aid of the Sun’s UV rays without increasing your pool’s cyanuric acid level.
However, you have to ensure it’s properly dissolved to avoid pinholes in your vinyl liner or bleaching the surface of your pool. Also, it alters the pH level of your swimming pool and best tipped in the evening.
2. Sodium Di-Chlor
This type is granular chlorine and dissolves a bit slowly. Unlike Calcium Hypochlorite, this type of shock lasts longer and comes with a stabilizer that raises the cyanuric acid level of the swimming pool. Plus, it is effective as either maintenance chlorine or shock treatment. Also, it’s best used in the evening.
3. Potassium Mono Persulfate
Potassium Mono Persulfate is type of shock that does not include chlorine. It works by oxidizing the water in the pool to get rid of contaminants and boost the working process of chlorine.
Unlike the other two kinds discussed above, this type can tip into your pool anytime during the day and resume swimming after a couple of minutes.
No doubt, there are lots of options to choose from; however, knowing the right type of shock to go for will help narrow down your long list of options. Sadly, it may not be helpful in figuring out the nuances that break or makes a product.
Let’s take a look at some of the key factors to pay attention to when looking to purchase the best pool shock for your pool.
Before the pool shock can be applied to the pool, it must be dissolved. Usually, this is done by most swimming pool owners in a separate bucket before pouring the dissolved shock into the pool.
Having the shock properly dissolved is important if you don’t want your pool liner bleached by the powdered shock granules.
As you can see, the speed at which the shock dissolve plays an integral role here. Fast dissolving granules allow pool owners to quickly add the solution into the water for a better efficient process. Besides, it reduces your chances of adding the un-dissolved powder to the water.
Level of Chlorine
The purpose of a pool shock is to keep the chlorine levels of your pool at a high level for a while, at least, to ensure that the sanitary of your swimming pool. Therefore, before buying any product, ensure you check the percentage of chlorine. Also, look out for its stability.
Many pool shocks on the market are not stabilized, which means that you only use them when the sun is down. This treatment has to be done overnight without the UV rays that acts as a catalyst to speed up the breakdown process.
It’s important to note that, there are pool shocks that do not include chlorine but still offer the same results – oxidizing the water to leave you with chlorine-free swimming pool.
Your pool water should be kept at a stable pH level, and a slight change can result in significant differences.
Let’s talk about what significant effects of changes in the pH levels can have: a low pH level can make the pool water corrosive and will damage any metal components, all pipes, or anything left in the water for long.
On the other hand, if the pH levels are high, the water becomes acid that irritates, hurts the eyes, nose, mouth, and ears of anyone having fun or relaxing in your pool.
Thus, it’s imperative for you to find a pool shock that will not have an effect on the pH level of your water. However, if you find that hard to achieve, then constant check the pH level of your pool water and bring it back to neutral after applying the shock solution.
As said earlier, it’ essential to ensure that whatever product you are going for has little impact on your swimming pool as much as possible.
Here’s the trouble, lots of pool shocks come with additional chemicals and compounds for effectiveness. Shocking regularly will leave your swimming pool with a lot of additive adding up real fast.
In short, using di-chlor to shock your pool means more cyanuric acid and cal hyp pool to increase the level of calcium in your water. While it’s not possible to purchase an utterly additive-free pool shock, but it’s better to buy a product with simpler options to avoid filling your pool with lots of unnecessary chemicals.
Liquid Vs. Powdered
Most pool shocks are available in the powdered form, which means you have to pre-mix before applying it into your swimming pool.
A liquid pool shock are better option for those who do not have the time or effort to pre-mix a shock. These products offer convenience since it’s already totally dissolved and can be tip straight into your pool. Sadly, there’s a downside to the liquid option, as it’s more pricey than the powdered option.
