Best Chlorine Tablets Reviews

Gardens are wonderful places to relax in.

If you are lucky enough to have a swimming pool in your garden, even better!

More and more people these days are choosing to install pools at home for that perfect combination of relaxation and exercise.

What’s not quite so perfect is the maintenance required.

Think about even a small garden pond. You’ll need a pond filter, pump and vacuum so that things run smoothly. It’s essential to need to keep on top of your swimming pool or hot tub as well.

Today, we’ll present 5 chlorine tablets reviews so that you can keep things as they should be.

We’ll also look first at the most effective way to add the best chlorine tablets to your pride and joy.

What Is Chlorine?

Chlorine was discovered in 1774 and falsely believed to contain oxygen. It was named in 1810. Humphry Davy who named it thought it was an element. This was again incorrect.

Chlorine is a diatomic gas which is green in color. It’s more than twice as heavy as air, has a powerful odor and is extremely poisonous.

In solid and liquid form, chlorine acts as a very powerful bleaching, disinfecting and oxidizing agent.

As well as bleach and the horrifying mustard gas, one of the principal uses for chlorine is as a crucial chemical for water purification.

Why Use Chlorine?

In a nutshell, you need chlorine to purify the water just as much as you’ll rely on a pool heater.

All pathogens and viruses will be removed from the water along with any organic matter or contaminants.

If you want clean and safe water for you and your family, getting a good chlorine tablets is a must.

How To Add Chlorine To Your Pool

You’ve got 4 main options at your disposal:

  • A chemical floater
  • A skimmer
  • Sprinkle granules directly into water
  • An automated chlorinator

Why Chemical Floaters Are Not So Good

The first option can be set aside. If you have a liner made from vinyl, the floater can get trapped on the wall and spill out chlorine in just one area. This can bleach the liner. Also, floaters are not very efficient. Water does not pass through properly and the chlorine will not be distributed evenly.


Be aware of the downsides if you opt for a chemical floater. We mention them because they often crop up on lists of delivery systems but you should take note of the drawbacks.

To Skim or Not To Skim?

A skimmer basket is the smart choice if you can only choose between a floater and a skimmer.

When your pool filter is chugging away, water travels rapidly across the tablets. This dissolves them properly. The return jets will pump the chlorine and spread it nicely throughout your pool.

Be careful when you turn off the pool pump, though. It’s best to remove the chlorine tablets if you’re using a skimmer. When the filter is not running, the tablets will dissolve and this concentrated solution can corrode your equipment. Another alternative is to invest in a variable speed pump.


Although they are a possibility, using granules is really not recommended.

Not only does this method eat up too much time, you’ll also run the risk of bleaching the pool liner.

Automatic Chlorinators: The Smart Choice

When it comes to dispensing chlorine accurately and steadily, you can’t beat an automatic chlorinator.

With one of these nifty tools you can add a large dose of chlorine in one hit. Simply sit back and regulate the output. No more endless applications of tablets.

Chlorinators will also guarantee that your pool liner is safe from bleaching.

For ease and pure convenience, it’s well worth spending out on a chlorinator. The price is negligible compared to the pool itself. Without proper chlorination procedure, your pool is at risk. Why take the chance?

Stabilized or Unstabilized?

Stabilized chlorine is generally added to outdoor pools. Cyanuric acid (CYA) is added to this type of chlorine to add a layer of protection against the sun. The most common unstabilized chlorine comes in liquid form.

The most regular format for stabilized chlorine is either the tablets we will look at today or sticks.

Tablets come in 1-inch or 3-inch form.

How Much Chlorine To Add To Your Pool

As a general benchmark for adding chlorine manually…

One 3-inch chlorine tablet covers 5000 gallons of water.

The math is nice and simple so for a 20,000-gallon swimming pool, throw in 4 of the best chlorine tablets.

Always round up. A 17,000-gallon pool? 4 tablets again.

If you are using an automatic chlorinator, just fill it up and then it’s down to tweaking the controls and delivery rate. Start slowly and build your way up. You’re not going to cause any damage with too little chlorine but you must avoid overkill.


Now you have an overview on the benefits of adding chlorine to the water in your swimming pool, it’s time to check out top 5 chlorine tablets.

All of these products deliver fully so it’s a question of finding the best solution for your pool maintenance needs.
