A Swimming pool requires a lot of chemicals to keep it clean and functioning. One of the chemicals is chlorine. Chlorine needs to be added into the pool frequently because it has low variability and it weakens with time. There are two types of chlorine- Liquid Chlorine and Chlorine Granules. Swimming pool owners often get confused about which one to use in their pool.
Liquid chlorine and Chlorine Granules are used for the same reason in swimming pools. Both are made for keeping your swimming pool clean. They work as pool sanitizers. They both have advantages and disadvantages, but it is very hard to tell which one is better as both of their functions are the same. You have to decide according to your need which one to use to sanitize your pool water.
What is Liquid Chlorine?
Sodium Hypochlorite is another name of Liquid chlorine. This chlorine is found in liquid form and can be added directly to swimming pool water without the hassle of making a mixture. It has a pH level of 13, which is quite high for personal pools. This will need further chemicals to keep the chlorine in balance. That is why liquid chlorine is mostly used in commercial pools like- swim academies, park pools or big pools in hotels, etc.
Also, the liquid chlorine can not be stored for a long time. People usually buy pool equipment in advance for personal uses. On the contrary, big hotels or swim academies need to use chlorine in their pools regularly, so liquid chlorine can be a good option for them.
What are Chlorine Granules?
Chlorine Granules are the powder form of chlorine. It can not be poured directly into pool water before mixing with water. It costs a bit more than liquid chlorine but saves from the extra chemical costs as the pH level is well-balanced in powder. So, no extra chemicals are required to keep the pool water safe and balanced.
That is why it can be a good choice for the pool owners who own a personal pool for their own use rather than for commercial use.
Difference between Liquid Chlorine and Chlorine Granules
In spite of having the capability to conduct the same functions of keeping your swimming pool clean and sanitized, Liquid Chlorine and Chlorine Granules have a few differences in their- condition, usage, ph level, storage ways, etc. between them. But that does not make any of the chlorine better or worse than the other. It just helps you to understand which is more suitable for your better chlorine use. The differences are described below-
Liquid chlorine or Sodium Hypochlorite is stored and used in liquid conditions. And Chlorine granules are stored as a powder, but it is liquified before use.
You’ll find Liquid chlorine as the easiest form to use because it can be poured directly into the water. There is no requirement for premixing. In contrast, chlorine granular needs to be melted or mixed in the right amount before using in the pool as it is kept in a powdered condition.
Liquid chlorine has a higher pH level than Chlorine granules, but still, granules work just fine as liquid as it has 35% calcium. But it has a higher chance to increase the hardness level of your pool.
Liquid chlorine or Sodium Hypochlorite has a limited lifespan. It expires very soon. So, it’s better if you do not purchase it in advance to keep it stored.
Chlorine granular costs more than liquid chlorine at the same time. It saves more for the long term as it does not require balancing pH levels separately.
Which type of chlorine is better for the pool?
Liquid chlorine is better for commercial swimming pools, and Chlorine Granules or chlorine powder is best for personal pools.
Which chlorine costs less?
Liquid chlorine costs less, but it increases the final costs if used for personal pools as there will be more chemicals needed to keep the pool pH level in balance.
Which chlorine form has more chlorine quantity?
Both have the same chlorine quantity but have different pH levels.
As mentioned before, no type of chlorine can not be declared as better than one another but can be better suitable for different types of pools. You just need to choose according to your pool type and your financial ability.
