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

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

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:

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

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.
