Selecting the Best Pool Shocks

Some vital factors cannot be ruled out before you buy the right pool shock for your pool.

Let us run down those points quickly:

1. Pool Type

Even if your pool shock contains strong chemicals this won’t affect your pool much or cause any problems.

But if you do not want that the vinyl liners of your pool get faded then any pool shock treatment that contains chlorine should be avoided. The smartest choice here would be a non-chlorine pool shock.

But if it is a fiberglass pool then you need not worry as any pool shock will be suitable for such pool type due to the reason that these pools are extremely tough and won’t be affected by any tough product.

2. Pool Size

The quantity of shock you will need for your pool will be dictated by the size of your pool. For an estimate, for every 10,000 gallons you will generally require 1 lb of a shock every time you use.

In case of some stronger shock treatments you will be needing a small amount only of the shock you use without effecting the overall results.

3. Pool Shock Types

There are some small differences in the pool shock types, though basic work of all of these is to shock your pool.

Let us know about the three main types separately:

Calcium hypochlorite

This consists of 65 – 75% active chlorine, which works strong and is suitable for almost any pool type.

It is advised that you should shock your pool in the evening as it shows sensitivity to the sun. Using the pool for swimming the next day is the most appropriate thing.

Sodium di-chlor

For maintaining your pool regularly this stabilizer ingredient-Sodium di-chlor is certainly an ideal option.

This shock type dissolves a bit slower in comparison to the calcium hypochlorite, and can be poured directly into the pool without the need of mixing it with water.

You can feed it via skimmer too.

Potassium peroxymonosulpate

This pool shock comes in a non-chlorine category and a really fast-dissolving one, the best part is you can use this pool shock at any time of the day without worrying about the sunlight.

Quickly after pouring it your pool is ready for swim.

Conclusion:

We hope you are left convinced with our choice of the best pool shocks. Selecting one apt product for your pool is essential for all the necessary salinization, safety, and appearance reasons.

Though all are great in their own way but one pool shock is our favorite i.e. In The Swim – Chlorine Pool Shock. Even the users love to use this chlorine pool shock.

One more we appreciate is the Clorox Pool&Spa Shock- XtraBlue due to its open and pour bottles.

You can even go a non-chlorine choice for your hot tub, pool, or spa.

Just mix it, shake it, and feed it in your pool water!!

Frequently Asked Question's

Q1. What Time Should I Shock My Pool?

Ans1. The time of using pool shock depends on the type of pool shock. Evening time is best suited for using a chlorine-based pool shock. As day time the sunlight minimizes the chlorine level and this won’t prove good for pool water.

But for a non-chlorine shock, you can use it at any time of the day.

Q2. Is Chlorine And Shock Similar?

Ans2. For pool sanitization, shock and chlorine share similar active chemicals. However the stronger is the shock in comparison to chlorine. The shock helps in raising the chlorine levels in your pool faster and the chlorine in turn keeps the pool clean, clear, and healthy.

Q3. How Often Should I Shock My Pool?

Ans3. You can choose an ideal frequency of pool shocking and that’s once in a week. This could be twice a week also if the pool is put to use frequently.

But if there are many swimmers, lots of rain, or stubborn algae then go for it daily for health and hygiene reasons.

Q4. Can I Shock My Pool Directly?

Ans4. Different brands offer different pool shock types which need to be used differently. You can use a non-chlorine shock or a lithium-hypochlorite shock without using water and by adding directly in the pool.

But using a shock with water is a safe thing and should be practised for best outcomes. This way the shock will dissolve faster too.

Q5. How Long Should I Wait To Dip In The Pool After Shocking?

Ans5. You can swim in your pool after shocking it if the chlorine level is about 5ppm. If you have a sensitive skin and are extra cautious for your health and skin then waiting for 24 hours is recommended after shocking your pool.
