This will also help you determine which type to use based on your pool, financial ability, and even the availability in the area where your pool is located. Let us see the different types of pool shock, and how these types differ.

1. Lithium Hypochlorite Shock

The first one on our list is the lithium hypochlorite which is best for pool water that has high calcium content. It is faster to dissolve compared to calcium hypochlorite, another type of pool shock. Since it is quick to dissolve, you can directly apply it to your pool even without dissolving it first. This type of shock can be hard to find since some pool chemicals manufacturers have stopped producing it because of the high cost of lithium. The commercial versions of this type of pool shock have 35% chlorine, and it is said that it must be used after dusk. If you used it for your pool shocking session, it would take at least 8 hours of waiting before anyone could swim again. This one can also act as one of the best algaecides since it is harmful to aquatic life. It is also a must to take precautions when disposing of this type of pool shock.

2. Calcium Hypochlorite Shock

The next one we have is the calcium hypochlorite shock. This is also known as cal hypo and has been used in the market for so many years to disinfect swimming pools and even public water sources. This is one of the most commonly used ones since it is cheap and convenient to use in the pool. If you are going to evaluate the content of commercial versions, they have at least 65 to 75% chlorine. Before you add this type of pool shock into your pool, you have to make sure that it is well dissolved, and like the lithium hypochlorite shock, this must also be used after dusk. You also have to wait for a minimum of eight hours before dipping into the pool again. When using this type of pool shock, always take caution on the level of calcium.

3. Dichlor Shock

This shock is also known as sodium dichloro-s-triazinetrione or dichloroisocyanuric acid. There are brands of this pool shock that can be directly added to your pool, so you have to always check the packaging. This pool shock is also applicable to saltwater pools. You can find almost 50 to 60 percent of chlorine content in this type of pool shock, you can also use this if you are just going to apply regular chlorine treatments in your pool. You also have to wait for roughly eight hours before taking a dip in your pool

4. Non-chlorine Shock

We also have a non-chlorine shock or use an inexpensive and fast pool shock alternative. This type of pool shock is recommended for saltwater pools. You do not have to dissolve this pool shock before applying to your pool, you can directly add it, and in just 15 minutes after application, you can return to swimming again! However, you also have to know that this type of pool shock will not kill algae since there is no chlorine involved.

When using any type of pool shock, you have to always check the container of the shock to see the specifications and doses based on the size and type of the pool you have. Some precautions must be taken and remembered before executing pool shock.
