What Should You Look for When Buying Pool Shock?

Knowing the type of swimming pool shock to buy can narrow your search query options and get the best shock treatment for your pool. 

Look for the following when buying the best pool shock:

1. Dissolving Speed in Pool Water 

Like Pool Essentials Shock Treatment, a fast-dissolving product minimizes the risk of pool damage from the harsh ingredients. 

You should consider getting a model that does not require pre-mixing to dissolve fast.

2. Chlorine Level in the Shock 

The right pool shock should increase the chlorine level to sanitize your swimming pool and remove algae and bacteria.

It is advisable to check whether the product is stabilized or non-stabilized. 

You will find that we have reviewed a non-chlorine shock in the products above. It has the same end effect as the chlorine shock.

3. Neutral pH Level 

Small changes in the pool water pH can make a difference and cause eye irritation. 

Ensure you get a swimming pool shock that does not interfere with the water pH, like Aqua Chem Shock Xtra Blue. 

4. Free of Additives 

Some pool shock products come with additional chemicals to better remove algae, contaminants, and other matters. 

Avoid such models because they might add calcium, cyanuric acid, and other chemicals in the facility. 

5. Liquid Vs. Powdered

You can buy a liquid or powdered pool shock, with most shock treatment products coming in powder form.

How to Choose the Right Shock for Your Pool?

You can choose the right pool shock for your swimming facility as follows:

1. Vinyl Pools 

Use a non-chlorine shock made of potassium peroxymonosulfate or an instant liquid made of calcium hypochlorite.

2. Fiberglass Pools

Use the above shocks for treating the vinyl pools or use Di-Zap dichlor based products like Pool Essentials Shock Treatment.

3. Concrete Pools

You can use the above shocks and others like Cal-Chlor sanitizers.

Note: Use Non-Chlor or Di-Chlor if your pool has a high level of calcium. Avoid Di-Chlor if the pool has high cyanuric acid levels; instead, go for non-Chlor and Cal Hypo shocks. 

What Is The Best Shock to Use in My Pool?

Swimming pool shock treatments come in different forms, with each type offering unique features and solving various water problems. 

However, their goal is to remove all contaminants from the pool, like pool algae and bacteria. 

The section looks at the different types of pool shocks on Amazon today:

1. Calcium Hypochlorite Pool Shock – Cal Hypo

Calcium hypochlorite or Cal Hypo pool shock is an economical pool shock you can buy from the market. 

It is available in 73% and 655 strengths and is not stabilized, meaning it can be affected by the UV rays – use it during the evening or night. 

Calcium Hypochlorite pool shock is also one of the most potent chemicals you can buy to kills bacteria, pool algae, and other matters.  

The product can quickly destroy the pool liner and most pool owners pre-dissolve the Cal Hypo in a bucket of water. 

One downside of Calcium Hypochlorite is the adverse effect of raising the pool pH and increasing the calcium levels. 

It can take up to 8-hours for the pool’s chemicals to balance.

2. Sodium Di-Chlor Pool Shock 

Sodium Dichlor pool shock or Sodium Dichloro-S-Triazinetrione is a stabilized pool treatment you can add during the day. 

It is available in 56% strength and does not agent calcium to the pool water. However, it can increase cyanuric acid levels. 

Sodium Di-Chlor is useful when you want to maintain a high chlorine level for an extended period, like Clorox Pool Spa Shock Plus. 

You can do that to disinfect your pool against bacteria, parasites, and other contaminants. 

Sodium Dichlor is more expensive than Calcium Hypochlorite and provides almost a neutral pH level.

You can swim in your pool after 15-30 minutes of adding Sodium Di-Chlor products like Aqua Chem Shock Xtra Blue.

3. Potassium Monopersulfate Pool Shock 

Potassium monopersulfate is a non-chlorine shock, making it different from Calcium Hypochlorite and Sodium Di-Chlor. 

It does not contain chlorine and is perfect for use in swimming pools that use bromine. 

The product is not affected by UV rays and helps to boost the free-chlorine levels in the water. 

Potassium Monopersulfate is the most expensive of the three types of pool shock, meaning that it is not the best for regular maintenance. 

Which is the Best Shock?

Calcium Hypochlorite is ideal for fitting pool algae and bacteria. 

Potassium Monopersulfate is recommending for sanitizing a bromine pool due to its non-chlorine shock qualities. 

Sodium Dichlor products, like Clorox Pool Spa Shock Plus and Aqua-Chem Shock Xtra Blue, are perfect for routine pool disinfection against bacteria and parasites.
