Best Chlorine Tablets – Buyer’s Guide

Now that you have gone through the 7 top chlorine tablets, you know why it is essential. Also, you know how it works, but do you know what qualities make for the best chlorine tablets? Here are the things to consider while buying chlorinating tabs.

Things to Consider while Buying Chlorine Tabs

Size of Your Pool

What size chlorine tablets are the best for you? The size of your swimming pool will determine the quantity and size of the chlorine tablets you need. If you have a regular-sized or large pool, buying a pack of 3-inch chlorinating tablets is the wisest option.

Your pool requires a regular supply of chlorine to prevent bacteria, algae-formation, and other germs. If you use a lesser quantity of chlorine, you may need to scrub and clean the walls of your pool more frequently.

On average, a 1-inch tablet will work fine for 5,000 gallons of water. On the other hand, you would require a 3-inch tab for 10,000 gallons.

Type of Chlorine Tablet

There are two types of chlorine tabs—stabilized and un-stabilized. So, which kind of chlorine tablet does your pool need? It depends on the location of your pool. Stabilized chlorine tablets contain Cyanuric Acid, which helps to protect your pool from UV rays.

That is not all. These tablets work better when they are exposed to sunlight. Quite the opposite of this, un-stabilized habits are not that effective under the sun. Therefore, while you can use the former for indoor and outdoor pools, the latter is only useful for indoors.


You may be wondering why is the packaging of the chlorine tablets a significant factor? These tabs are highly concentrated, containing large amounts of chlorine. If you are exposed to the chemical or are in direct contact, it may lead to irritation in the eyes, skin, and nose.

Another significant factor to consider is that if the chlorine tabs are not wrapped well, they may turn into powder. It happens during the delivery process and is inevitable until you choose to purchase them from your local store.

You must know that while powdered chlorine will still be as effective, it will dissolve in a jiffy. Therefore, though you will get extra-clean water, it will only last for a short while. Consequently, it would be best if you preferred chlorine tabs that are individually wrapped.

Chlorine Concentration

You are buying these tablets to maintain the chlorine content in your pool water. So, high chlorine concentration is an absolute requirement. When you check the pack label, you will see an ingredient named Trichlor. It is an active ingredient that reflects almost 90% of chlorine content.

Now you know what ingredient should you look for on your chlorine tab pack.

Ingredients and Functionality

You may find several options that contain a plethora of other useful chemicals packed in one single tablet. These work as an all-rounder in protecting pool water from bacteria and algae along with equipment corrosion and stain.

Therefore, you can choose one that works well for multiple problems. These are also helpful as you will not need other products and chemicals.

Final Words

Having read the product review of the 7 best chlorine tablets and a helpful buyer’s guide, have you made your decision? Chlorine tabs are quintessential for the health and condition of your pool water. However, choosing the wrong product or dosage may not prove to be satisfactory.

Make sure you compare all your options and choose the one that is suitable for your specific pool type. What’s ahead? You can maintain a germ-free pool and enjoy long hours of swimming without the hassle of cleaning!
