Things To Consider Before Buying Pool Chlorine Tablets

You have already known that chlorine used in swimming pools comes in either tablet, powder, or liquid form. There are some nuances you should be aware of before pulling the trigger on a purchase.

Each form has its benefits and downsides. Different price-points, applications, and overall effectiveness in specific situations draw a margin as well. There is no one-size-fits-all.

Here are a few pertinent factors to consider when purchasing a chlorinating product;

Nature of Chlorine Substance

Chlorine sanitizers are typically used with a dispenser that allows them to be released into your pool consistently over time. The easiest form of chlorine to use is in tablets. It is friendly to most domestic pool owners. It is eco-friendly as well for commercial pool owners. Tablets can also contain other helpful substances such as algicide and water clarifier, eliminating the need to purchase and add them independently.

Stabilized or Unstabilized Chlorine

  • Unstabilized chlorine has not been mixed with cyanuric acid (CYA). This chemical shields your chlorine from the sun’s ultra-violet (UV)-rays. (UV)-rays decreases the overall burn-rate of your dosage.
  • Is your swimming pool outdoor?

Not all swimming pools are outdoors, exposed to the sun. Unstabilized chlorine can be used to the same effect in the right circumstance.

Besides, you can add the CYA at will when needed. This type of chlorine has a shorter lifespan than stabilized chlorine. It can be used in large doses to shock your pool, or even as an emergency top-up. It quickly restores falling chlorine levels.


  • Fast burn-rate when exposed to the sun
  • Typically used with indoor or shaded pools
  • Used to shock pool or for top-ups
  • Stabilized Chlorine as you guessed it, is chlorine that has been mixed with cyanuric acid (CYA). It protects your chlorine from the sun’s ultra-violet (UV) rays. Again, the added acid is important for swimming pools that are frequently exposed to the sun. Having it mixed in with your chlorine just makes your life easier when it comes to dosages.

However, most tablets come with stabilized Chlorine. The essential chemicals have been added and balanced to working efficiency.


  • Slow burn-rate when exposed to the sun
  • Typically used with outdoor pools
  • Easier to manage

A common example of stabilized Chlorine Compounds is Lithium Trichlor. This type slightly reduces the pH and total alkalinity of your pool water.

Lithium Trichlor, simply called “Trichlor” comes in powder and sometimes tablet form, and it contains around 90% available chlorine. This is a strong, dry structure with the most elevated chlorine content.


Chlorination is the cheapest and generally most effective method of achieving sanitation of pool water. To inactivate the pathogenic microorganisms that remain after use, a sustained release effect from a chlorinating substance, a tablet, is ideal. All of the listed chlorine tablets are cost-effective and eco-friendly. There is a little margin in the price points. This is however due to the quantity of chlorine present in pounds of tablets. The active ingredients are most essentially the same. If you need the serving for a small size backyard pool, you may consider buying in low-pound quantities. A product like the 4Lbs quantity might serve you best for the sanitation period. A commercial pool may need a stock of large quantity, hence higher cost. The frequency and length of treatment have to be on the high side for effectiveness.


Does Chlorine Prevent All Water Infections?

Chlorine in swimming pools kills the germs that may easily be contracted as diseases. Although it takes time. Chlorine in properly disinfected pools kills most germs that cause water infections within minutes. However, it may take longer to kill certain germs owing to some factors. Anything that can reduce chlorine levels in pool water may be a cause. Examples are sunlight, dirt, debris, and material from swimmer’s bodies (organics). Chlorination and healthy swimming behaviors are needed to protect you and your family from germs getting in the pool.

How Long Do I Wait After Chlorination before I Use Pool?

It is sheltered to utilize your pool after synthetic compounds have scattered all through the pool. It usually takes 15 minutes to one hour. When shocking your pool, wait until the chlorine levels drop to recommended levels.

Do I have to Remove the Chlorine Tab Wrapper before Use?

Try not to put chlorine tablets straightforwardly into the pool. They will stain and etch the pool plaster esp vinyl liner. Simply remove the tab from the bucket and leave it in the wrapper and place it in your pool. You need to use dispensers although.

How can I reduce the Itchy Skin Effect from Chlorination?

Clear off all appearances of dirt and organic debris from your pool before Chlorination. Chloramines cause itching to the skin. Chloramine is formed when chlorine reacts with body contaminants. Keeping the level of contaminants low will reduce chloramine levels.


You can now make a smart choice of the best pool chlorine tablets having gone through the review. I recommend the products itemized in this best pool chlorine tablets review. They stand the test of time and have gained good reports from many pool owners. You have invested a lot in your pool, so the best cleaning chemical is not altogether overmuch.
