What to Do Before Buying the Pool Shock?

Keep reading our article to discover how to take care of your swimming pool.

First of all, there are three types of pool shock.

Calcium Hypochlorite, the most popular and powerful kind of pool shock

You know what?

This product is easy to dissolve and getting burned by the sun’s rays does not alter cyanuric acid levels in your pool. Also, the pool pH will increase after you add it.

And remember: Apply it in the evening when no one uses the pool and re-use your pool only when the level of chlorine has normalized.

Sodium Di-Chlor, slow dissolve and in the form of chlorine powder

When comparing the solubility with calcium hypochlorite, this type retains in the pool longer.

Besides, its composition contains a stabilizer that increases the level of cyanuric acid in your pool. It can also raise the pool pH level.

When to use?

Use it in the evening, too. Everyone can jump into the pool after about 30 minutes when the chlorine level has decreased.

Potassium Mono Persulfate: Chlorine-free, oxygen-containing components

In fact, this product is different from the two first types when you can apply it anytime and use the pool immediately thanks to its oxygen composition.

Coming with that, the pool cyanuric acid doesn’t change when added this shock.

To oxidize the pool for pollutant elimination and to promote the chlorine effects, you can use this shock.

What’s the reason for choosing the right pool sock?

To not damage your pool or make the condition worse, you should use a right shock to match the water composition or chemistry, the pool type and the purpose of shocking.

Here are some notes for you:

  • Use one of three types when cleaning water weekly or for fiberglass and concrete pools.
  • Can use Calcium Hypochlorite if the water is green.
  • Use Potassium Mono Persulfate for vinyl pools and for sanitizing bromine, maintenance every week or before a heavy pool use.

Yearly Shock Amount for Your Pool

It’s time for you to get your money’s worth with the pool shock.

  • How often do you use the pool? The more you use, the larger amount you need.

Which One Is A Suitable, Powdered or Liquid Shock?

Between these two types, the liquid shock is better because it does not harm any pool you own.
