Applying Chlorine Tablets In Your Pool: A Short Guide

Chlorine is hugely important in the function of a pool.

It sanitizes and keeps your pool water clean, meaning you can swim in a germ free zone.

To add chlorine to a pool, you can do so in the form of granules, sticks, and tablets.

Out of these three, chlorine tablets are the most commonly used.

In fact, they are considered to be the most effective at cleaning a pool and their ease of use means they are the most efficient too.

These tablets simply dissolve slowly and allow chlorine to be released into the water. All you need to do is sit back and let it do the work.

Whilst using chlorine tablets is relatively simple, it can be confusing when knowing where to apply them in your pool.

It’s important to understand the correct ways of doing this, as you could cause damage to your pool if you add the tablets incorrectly.

Read on as we guide you through the process of adding chlorine tablets to your pool quickly and easily. 

How To Add Chlorine Tablets To Your Swimming Pool

You may think that you can simply throw a chlorine tablet into a pool and let it work its magic. But, the reality is, you should NOT do this.

If you just let a chlorine tablet loose in pool water, it will dissolve on the base of the pool.

This can lead to a bleached stain on the concrete or liner that can be permanent. 

Instead, you should apply your chlorine tablets to the pools’ skimmer (see also ‘What Is A Pool Skimmer Weir?’), automatic chlorinator, or a floating dispenser. 

Adding A Chlorine Tablet To A Skimmer

Putting chlorine tablets in your skimmer is one of the simplest and most effective ways to distribute chlorine.

By doing this, you will be free of any fuss, and, best of all, no additional equipment is required.

The skimmer provides a great area to disperse chlorine because it has a continual stream of water going through it for much of the day.

It will also equally distribute the chlorine over a gradual basis.

Adding A Chlorine Tablet To An Automatic Chlorinator (Chemical Feeder)

An automatic chlorinator (see also our article on automatic pool chlorinators) is one of the most efficient ways to chlorinate your pool.

All you need to do is  place your chlorine tablets in the chlorinator and adjust to the desired chlorine level.

This allows you to add the exact chloride concentration to your pool, eliminating any guesswork.

If your pool does not have an automatic chlorinator, you will need to purchase one.

But, think of it as a wise investment as it gives you complete control over the flow rate and eliminates any chlorine waste.

Chlorinators are separate from the pool, but typically work at the filter site.

As well as tablets, you can also use granular chlorine and liquid chlorine in these, but this depends on the equipment you’re using.

Using a chlorinator should prevent your chlorine levels and acidity from spiking.

This means that no bacteria or green algae should grow in the future.

Although you should still test your water on a daily basis to verify adequate levels, using a chlorinator will deliver better consistency and require less maintenance every day.

Adding A Chlorine Tablet To A Floating Dispenser

Here is another option when using chlorine tablets. Floating dispensers are wonderfully easy to operate and work well.

All you need to do is fill the dispenser with the appropriate number of tablets and allow it to simply float around the pool.

As the tablets break down, the chlorine will be released and begin to sanitize the water.

One difficulty, however, is that it may become trapped in an area of the pool.

If this happens, it could prevent the chlorine from being distributed uniformly.

Using these methods, you should be able to keep your pool’s chlorine levels at a consistent threshold.

Generally speaking, you should be looking at levels between 1 and 3 ppm (parts per million).

In Summary

We hope this article has helped you understand how and where to place chlorine tablets to keep your pool sanitized.
