A dirty pool that is not well taken care of is the most eyesore to anyone and you got to do your part to ensure it is in a good state off-season and in-season. Chlorine is best known for having your pool clean in the shortest time possible.  The floating dispenser and the automatic chlorinator are both known to do a good job when it comes to chlorinating your pool at the end of the day.

A Floating Dispenser or an Automatic Chlorinator

The floating dispenser and the automatic chlorinator assist you with the dispensing of chlorine into the pool, giving you an easy time on the whole clean-up issue. The chlorine comes in pukes which are fed into the floating dispenser and the automatic chlorinator and they proceed to release it into the pool in small amounts. This article will give highlight the two mechanisms and highlight their shortcomings and the advantages of each. I will give a final verdict at the end of the article to let you know what is working for my pool.

Automatic Chlorinator

Inline vs Floater Chlorinator

The first thing that comes to your head with the term automatic is the fact you do not have to do much apart from setting the whole system up and deciding on when the chlorine will be released into your swimming pool. The automatic chlorinator is also referred to as the chlorine feeder as it feeds the swimming pool with the chlorine pukes in small amounts at a stipulated time.

How does the automatic chlorinator work?

The pool has other machines that work in hand with the automatic chlorinator to ensure the pool is in great condition. The automatic chlorinator, the filters, and the pool pump all work in sync at all times to ensure the pool is maintained in good condition.

The great thing about the automatic chlorinator is that you are in control of the amount of chlorine that will be released into the pool and the rate. With the help of a valve on the automatic chlorinator, you could switch it off once its job is done.

Types of automatic chlorinator

Something to note about the automatic chlorinator is the fact that there are two kinds of automatic chlorinator; one being the off-line chlorinator and the other being the in-line chlorinator the difference between the two is how they are conjoined into the pool to release chlorine.

The off-line automatic chlorinator is drained into the pool from a different source, this gives you the power to have it uninstalled when not in use or install it when there is a need. On the other hand, the in-line automatic chlorinators are found in the water return pipe of the pool and they are installed permanently, they cannot be uninstalled.

The automatic chlorinators will not have you breaking your back to have it working in good condition. There is one thing you should do to have it in great condition; have the O-rings lubricated using the silicone lubricant and be sure to have the cap replaced from time.

Sure this is a little task compared to what other pool chlorinators will have you go through. You need to inspect the pipes to be sure there are no leaks of any kind as it could be dangerous to have chlorine spilling.

How to refill your automatic chlorinator

Be sure to have all the precautions taken as stated by the manufacturer first before proceeding to have the chlorine pukes into the feeder pipes. Once everything is set, proceed to have the cap on the automatic dispenser turn, when open give the fumes time to escape from the pipe then proceed to have the chlorine pucks into the feeder.

Kindly take the needed precautions to avoid any kind of accidents. Have the pipes checked for any wear and fix it up in case of any damages. The inspections of the pool will have your pool in great condition all year round.

Best Chlorinator for In-ground Pools

Pros of the Automatic Chlorinator

Some of the things that made using automatic chlorinator ideal for anyone with a backyard pool include the following;

The low maintenance

The maintenance that you will need for your automatic chlorinator is close to nil. You will only need to have the O-rings lubricated after feeding the chlorine pucks and replacing the cap which is way easy for maintenance.

The automatic chlorinator is easy to maintain as it is built in the swimming pool and water goes through it before the pump and the filter system. The automatic chlorinator build-up structure will have the filter system serve you longer and better; this is attributed to the fact that the parts will avoid damage brought about by chlorine.

Worries aside with the automatic chlorinator as your pool will continuously enjoy chlorine clean-up even when you are far away; so goodbye to any of the green algae family in your pool.

Safety measures

Inline vs Floater Chlorinator

The automatic chlorinator being in-built makes it safe for everyone using the pool. The fixtures are done outside the swimming pool making it safe for children to play in the pool. This is unlike the floating chlorinators which pose a challenge when having toddlers in the pool.


The fact that you will not have pipes all over your pool with the automatic chlorinator is pleasing to the eyes. You will enjoy a clean pool without having the obstruction of pipes in your pool. With the installation of the automatic chlorinator, you will not see any pipes crossing your pool letting you enjoy an algae-free pool with no obstruction.

Your pool will not suffer from any kind of staining that is brought about by the use of chlorine at any point. It will remain clear at all times as the chlorine is not released into the pool but the pool water goes through it.

Ease of use

With the automatic chlorinator in place, all you have to do is sit back and enjoy your clean pool. You will have to set the timer which will dictate and control the amount of chorine that is released into the pool. All you will have to worry about is the chlorine pucks as you have to refill from time to time to ensure your pool is well chlorinated at all times.


The automatic chlorinator allows you to pick between having it in-line or off-line. Each of these options has its advantages as they all same the role in ensuring your pool is well disinfected at all times. You could opt for the off-line whereby you could decide to have it plucked out when not in use, unlike the inline automatic chlorinator.

Cons of the Automatic Chlorinator

Below are some of the things that were not favorable for me;

The installation

The inline automatic chlorinator could pose a challenge in the installation in an already existing pool. It would not be easy having it in place when the pool pump and filter are already in place. You will need to go for the offline automatic chlorinator which will give the same service as the inline chlorinator.


The automatic chlorinator is pricey and it will have you think of adding the chlorine to your pool water by yourself. The installation and the purchase take much of the expenses, aside from that you will need to have an engineer check on the job that was done to ensure there are no kinds of mishaps on the job done. Failing to have the inspection done may cost you more in the long run, so that is not a cost you can avoid.

Repairs and maintenance

The two are things you cannot avoid to have done. You need to have the pipes leading to the pool inspected from time to time. In the case of a leakage, you have to hire a professional to take care of the damages and have it fixed in record time to avoid further damage.

Awful experience

The pile-up of pressure and gas found in the pipes offers an unpleasant experience. The sad part is you cannot avoid refilling your chlorine pucks despite the fact the buildup gas will bust open once you remove the cap from the pipe. Be sure to have your face away from the gas.

Buildup in the pipes

There are times buildup in pipes may be experienced brought about by gas blockage in the pipe. The blockage in the pipe will affect the amount of chlorine released into the water and you will not get value for your automatic chlorinator. Insufficient chlorine release to your water will have your pool filled with algae without you realizing the problem.

Floating Chlorinator

The term floating is what this cup looking like does in your pool with pucks of chlorine in it. It does its job while it stays afloat in your pool. The water in the pool simply goes through it and it is chlorinated keeping your pool safe all through.

The chlorine pucks in your floating chlorinator get dissolved into the water creating an acidic environment for your pool killing the germs leaving your pool safe and clean. They do a great job in having your pool sanitized at all times. The kind of lifestyle you would wish to achieve for your pool will guide you on whether to go for the floating chlorinator or not.

Pros of the Floating Chlorinator

The floating chlorinator is straightforward in the usage and the pros of using it are quite in front of your eyes. I am going to expound on the advantages of using the floating chlorinator.

Not pricey at all

You could purchase a floating chlorinator for as little as $20 which is very cheap making it affordable for everyone with a pool.  The price of the floating chlorinator beats the automatic chlorinator as much is not needed for the installation.

You will only need the chlorine tablets in your floating chlorinator then have your floating chlorinator afloat in the pool. The structure of the floating chlorinator will have come up with ideas and you could even have one made at home. A small bottle with holes on it, have your chlorine tablets in it then place the bottle in the pool. The bottle will float around the pool as it sanitizes it.

Easy to use

Once you have purchased your chlorinator and you are at home, you will simply have the chlorine tablets in your floating cup-like structure. Have the floating chlorinator in your pool, it will float around the pool and water will go through the cup. The floating chlorinator has vents that are adjustable allowing the pool owner to decide on the amount of chlorine dispensed into the pool. You have an easy time using the cup off-season and when opening the pool again during summer.


The floating chlorinator comes in different designs for you to choose from. When deciding on the perfect chlorinator for your pool, you have a variety to choose from despite the material of the floating chlorinator being plastic.

You can choose different colors that will give your pool a theme to look forward to. The presence of the vents on the floating chlorinator will have you deciding on the amount of chlorine to be released into the pool.  The design of the vents gives the chlorine dispenser a completely different look. Pick a dispensing cup that will be of service to you for your pool.

Cons of Floating Chlorinator

Using the floating chlorinator, I experienced a couple of hitches with it and they are as follows

Amount of chlorine

I noticed that I needed to have chlorine in storage at all times. The dispensing cup will not hold large amounts of chlorine tablets and will need you to refill it now and then. Aside from the amount of chlorine in question, filling up the cup will have you handling chlorine with your bare hands which is not a great job. Be sure to thoroughly clean up after that to avoid damage by chlorine on your skin.

Safety precautions

The floating cup in your pool does not provide a safe environment for toddlers to swim in. Children being curious will have them touching the cup from time to time which is not advisable. The design of the floating cup will have them thinking of it as a toy and they will focus on it. This poses a danger in the pool and the floating cup will cause more havoc to kids who will hold it from time to time. If you have toddlers in the pool, this will not be a great idea for you to clean your pool with.

Manual checkup

For you to be sure you are getting enough chlorine dispensed into the pool, you will need to check with your floating cup now and then to make sure there are enough chlorine tablets to go about cleaning the pool.

If the chlorine tablets are dissolved, you will need to replenish the supply by adding more tablets to your cup. The task is not a pleasant one and you have to face away when doing it to avoid exposing your face to the fumes that have build up in the cup over the period. Take the necessary precaution when refilling your cup.


Your floating chlorinator is made of plastic to enable the nature of its job, which is to float in the pool releasing the chlorine. The cup will be exposed to sunlight all through, with the constant heat from the sun, the cup will tend to fade in color even though you go for UV-resistant plastic material. In cases where the plastic material is not tough, it tends to crack after a couple of months. You may need to replace it or repaint it. Repainting it will have you regret since the chlorine will have the paint chipping from the cup.


The presence of a pool in your backyard is a great idea for the summer season as you will need to cool off the heat.  Maintaining the pool whether an above-the-ground pool or underground pool requires consistent clean-up of your pool and sanitization with the use of chemicals. Chlorine tablets are known to do a great job in killing all germs in your pool and will face out any algae in the pool. The release of chlorine in the pool will have you deciding on whether to have the automatic chlorinator or the floating chlorinator in place. Depending on how much you are willing to spend on ensuring your pool remains clean off-season and in-season the two have a very different price range. The floating chlorinator is easily available and you could create one for yourself while on the other hand, the automatic chlorinator is pricey. The decision you make when purchasing between the two will entirely be based on the convenience you get from each of the chlorinators.


What is the best way to chlorinate a pool?

Having a pool is of great convenience to you. Deciding on whether it is above the ground or underground you still have to think of a reliable way to sanitize your pool off-season and in-season. The option available is of dispensing chlorine tablets into your pool from time to time. You will require a reliable way to have the chlorine tablets into the pool to clean the water. The presence of the automatic chlorinator in place and the floating chlorinator will have you deciding on what will work the best for your pool and what is affordable for you.

The floating chlorinator offers a cheap and reliable option for you as it is not pricey at all. The vents on the cup allow you to dictate the amount of chlorine to be released into the pool. On the other hand, we have the automatic chlorinator which allows you to make the necessary settings for chlorine to get released into the pool at intervals.

The downside of the automatic chlorinator is the price which may scare you away. The automatic chlorinator comes in handy for individuals who travel a lot as it will continue releasing chlorine into the pool as required. The decision entirely depends on what will work for you as both options provide a reliable solution to maintaining your pool.

How long do pool chlorinators last?

When in search of the perfect pool chlorinator you would like to know how long it will serve you before you need to buy another one. It is for you to know the value of your money when deciding on the right pool chlorinator to go for.

A good floating chlorinator with the right measures in place will last you close to three years in the pool before the need to have it replaced arises. The need to replace it will be due to the wearing out caused by the sun as it floats since it is continuously exposed to the sun. The UV-rays will wear the plastic down in the first couple of years having it fade in color. It will proceed to crack after the second year if the necessary precautions are not taken.

For your automatic chlorinator in good condition, it will last you close to seven years with the necessary precautions in place. With the automatic chlorinator, you will need to check on the pipes all the time to ensure there are no leaks whatsoever. Leaks in the pipes may cause unprecedented damages costing you a fortune.  With the pipes in good condition and the valve in mint condition, your automatic chlorinator will last you seven years before replacing it.

Are pool chlorinators worth it?

Failing to invest in a pool chlorinator will mean exposing yourself to dirty water every time you get into the pool. Your pool will be home to algae which will have you avoid the pool.

A worthwhile pool chlorinator will sanitize your pool from any kind of organism keeping away algae and any other micro-organisms. Chlorine in your pool will have you spending little time in maintenance letting you enjoy a clean pool. The right pool chlorinator will have you spending a minimal amount of money on chlorine granules as you tend to use less chlorine with the automatic chlorinator.
