A Must Read: What Is The Best Pool Brand?

In this short read, you will understand the difference between liquid chlorine and a powder one. It will give you enough information to decide which one to choose.

The Basics Of Chlorine

Chlorine is the most known chemical when it comes to pool systems and maintenance. It is used to sanitize your swimming pool and widely used by pool owners to kill all bacteria and algae. It is essential, so your pool is clean and safe to use.

You need to be aware that chlorine is an unstable chemical. It will degrade and breakdown as time passed by, especially if it is directly under the sun’s UV rays. It is why it is recommended to test your water and administer the chlorine level regularly.

Liquid Chlorine

Liquid chlorine is made up of bubbling gas through caustic soda. It has a pH level of 13 and can be administered to a pool directly into the water. Liquid chlorines are mostly used in commercial environments such as public pool and leisure centers ad it can be monitored in bulk from different large drums.

When it comes to the smaller and domestic pool, you will find out that the cost outweighs the performance. Due to a high pH level, you need to balance the pH back to 7.2 to 7.4. As most of us know, liquid chlorine is highly corrosive and can lead to damage if the administration is improper.

Powder Chlorine

Powdered Chlorine is one of the most common forms of chlorine used in your regular in-house pool. One big difference with liquid chlorine is that powdered chlorine is more expensive. But the great news is that it can be easier to use and contains a lower pH level.

That means it will give you less impact on your pool’s overall performance. There are three types of powdered chlorine to choose from. For instance, there is lithium hypochlorite, Di-Chlor, and calcium hypochlorite.


Overall, it will depend on your competency, budget, and the equipment you have in your pool. If you are looking for a budget-friendly approach, gram for gram liquid chlorine is the cheapest option.

But, always remember that there is an associated cost of balancing and the potential cost for mistakes. If you only have a domestic environment, choose a powder one. Otherwise, you are most likely to get the liquid version.
