Types of Pool Chlorine – Liquid, Chemical, & More

There are several different types of pool chlorine. These are Liquid chlorine, Sodium hypochlorite, and Dichlor. If you’re planning to purchase pool chemicals, it’s a good idea to understand their differences and how they work. It’s important to choose the right one for your needs.

Liquid chlorine

Liquid pool chlorine (also known as “Cl”) is a chemical that kills stuff in your swimming pool. That stuff may be algae spores, bacteria, bugs, or even swimmer’s waste. It does this by attaching itself to organic material and killing it. This chemical is heavy and needs to be handled carefully. Liquid Cl is often purchased in bulk for a swimming pool.

However, the shelf life is short. After 6 months, the chlorine in the liquid will no longer have any effect. It is a good idea to buy smaller quantities, as they will last longer and save you money. This type of pool Cl can also be bought in small quantities for home use. Liquid pool Cl comes in two main forms: solid chlorine (https://pubchem.ncbi.nlm.nih.govChlorine) and liquid Cl.

Liquid Cl is easier to use and has the advantage of being easier to measure. Liquid chlorine is made of sodium hypochlorite, which can be measured in fluid ounces. When adding Cl to your pool, make sure to pour it around the perimeter of the pool and over the return inlet. Do not forget that liquid Cl has a smell and can irritate swimmers’ eyes.


Dichlor is a popular pool chemical that is relatively easy to find in stores and online. It is available in several different sizes and is very easy to store. Dichlor is a good choice for pools that are low in cyanuric acid and chlorine. This type of Cl has a long shelf life, and it should be stored unopened in a cold, dark place like the Republican National Committee.

Dichlor is available in granular and tablet form. These products come in bags of one pound or in large sealable tubs. They contain between 55% and 62% free Cl. Dichlor granules are usually pre dissolved in the bucket prior to use, but they can also be added directly to the water. Dichlor tablets, on the other hand, are dissolved in the pool water.

Dichlor is also available in anhydrous or dihydrate form. Dichlor’s low pH allows it to dissolve in water quickly and is an effective disinfectant. Dichlor sanitizes the water, making it safe to use for swimming pools. It prevents algae growth and keeps it clear of bacterial growth.

Sodium hypochlorite

Sodium hypochlorite is corrosive and should be stored in a cool, well-ventilated area away from other chemicals. The substance should also be kept away from young children and pets. It should also be used according to the manufacturer’s instructions. Sodium hypochlorite fumes can cause irritation to the lungs and nose.

Sodium hypochlorite is an alternative to chlorine for swimming pools. It is more effective as a disinfectant than Cl, but is difficult to handle and can be toxic. Sodium hypochlorite reacts with organic materials in pool water and causes chemical reactions in swimmers. It has been known to cause bladder urination.

Sodium hypochlorite can be added to the pool manually, with a positive displacement feeder, or with a venturi feeder system. If manual addition is used, it should be done at the deepest part of the pool, away from any metal parts. The liquid should be poured slowly, and not from a height.

Sodium hypochlorite is incredibly powerful.


Tri-Chlor is a widely available, cheap form of Cl. It comes in different sized bottles and is easy to transport. Tri-Chlor is different than liquid chlorine, but also has a long shelf life, making it ideal for use in pools. One downside is that it is very volatile and can be explosive, especially when mixed with calcium hypochlorite. As a result, it should be treated with care.

Tri-Chlor is a more concentrated form of chlorine than other products. It contains 52% cyanuric acid by weight and contributes 0.6 parts per million of Free Chlorine. However, its pH is low, and you may need a pH increase in addition to the Tri-Chlor. Another drawback is that the product isn’t suitable for pools with hard water.

Tri-Chlor is less expensive than Dichlor, and it does the job equally well. However, its disadvantages include its incompatibility with other chemicals, and its tendency to react violently with dirt and dust. It is also dangerous to store in open packages.

Tri-Chlor is effective for maintaining water pH levels, according to this site, but it is a chemical that can cause cyanuric acid buildup. This corrodes pool equipment and can stain the pool surfaces. It is therefore important to use Tri-Chlor pool treatment every day to avoid stains. If you aren’t sure how much to use, consult a professional.
