Buying Guide for Pool Shocks

Swimming pool shock is among the most often used chemicals when it comes to pool maintenance. You will use it when the pool is first opened, throughout the swimming season, and when you close it in the fall. Be careful when using it because it may raise the pool’s chlorine level quickly. It is a good idea to test your pool water with test strips or test kits to check the chlorine level before using shock.

Types of Pool Shock

Pool shock comes in two forms. You can purchase it in a granular form or in a liquid. You might hear granular shock being called powdered shock. It is available in one pound or larger packages. You may also see it being sold in buckets weighing between 10 and 25 pounds as well as in cases containing several one pound packages.

Buying shock in bulk can save you money, but you don’t want to have any left over at the end of the season. It only has a shelf life of one year. If you use it after the expiration date, it won’t be as strong. This could result in chlorine levels that are too low. You should be purchasing new pool shock each year.
How Much Do You Need?

How much pool shock you need for each swimming season will depend on several factors. The first factor will be the actual size of your pool. Once this is established, you will need to take a closer look at the pool’s water. If the water appears green after the winter season or becomes green often, you need to use more shock. Those with mesh pool covers also find they need to use more shock than those with solid covers.

Consider how often your pool is used when you purchase shock. The more often that you and your family and friends are using the pool, the more often it will need shocked. People will naturally leave bacteria behind when they swim. This uses more of the chlorine. If your chlorine level drops frequently, you will need more shock each season.

Liquid or Powdered

When deciding between granular or liquid shock you need to make sure the pool shock won’t harm your pool’s vinyl liner. There is very little risk of hurting the liner when you use a liquid shock. Granular shock needs to be added carefully to avoid causing damage. If you do have a vinyl lined pool, read the packaging carefully to make sure the granular shock is safe.

You don’t have this worry with a cement swimming pool. Adding either type of shock directly into the pool will not harm it. The only concern would be with using granular shock which can accumulate in piles that will need to be dispersed with the use of a pool brush. When you add shock to any type of pool it is advisable to pre-mix the shock or else use your pool’s recirculate option to avoid deposits of shock on the pool floor.

Ingredients to Look For

Before you purchase pool shock you will want to check the label to find out what it is created from. This holds true for both liquid and granular shock. You are looking for two things. This would be the active and inert ingredients.

You want a pool shock that includes plenty of active chlorine. Don’t let the brightly colored labels and packaging fool you. You want to always make sure you know exactly what the shock is made from before buying it. If you are searching for it online and cannot read the label, look the specification page over closely.


If you are looking for a complete pool shock system to get your pool ready for the summer swimming season, the In the Swim Super Pool Opening Chemical Start Up Kit is ideal. Each pre-measured kit is formulated with all the start-up chemicals you’ll need. It eradicates bacteria with the chemical shock, and it removes and prevents rust, stains, and scales as well. This shock treatment uses a non-metallic algaecide to get rid of any algae while the clarifier enhances the performance of the pool’s filter. It even comes with test strips so you can measure the pH, chlorine, cyanuric acid, and alkalinity of the water.

On the other hand, if you simply need a reliable pool shock that won’t blow your budget, try the Clorox Pool & Spa Shock Xtra Blue. It comes in a variety of sizes so that you can select which one will best suit your needs. It is reasonably priced, and it comes from a brand name you already know and trust. The blue algae killing crystals can be seen as you pour it from the easy to open bottles. It kills as well as prevents black, green, and mustard algae from forming.

Those looking for a fast acting product can invest in the 50 pound bucket of Zappit 73% Cal Hypo Pool Shock. It only takes one pound to provide 2 ppm of chlorine in 40,000 gallons of water. The formula comes in the form of fast dissolving granules that provide quick action against algae. This large quantity will last through several treatments while giving you pool water free of bacteria.
