What is a Chlorine Tablet?
Chlorine tablets, also known as chlorine tabs, are dense tablets containing chlorine that are used to treat still water in a swimming pool to prevent bacteria and algae growth.
What Types of Chlorine Tablets are there?
Getting your pool sanitized and safe requires knowing what types of chlorine tablets are available and which will suit your needs. The most common types include:
Stabilized Chlorine Tablets
These stabilized chlorine tabs is most suitable for use in outdoor swimming pools since it lasts for a long time. Stabilizers slow down the dissolution rate of chlorine in the presence of sunlight.
Outdoor pools’ use of these products is due to their presence of CYA, which protects chlorine in the swimming pool water against the UV rays of the sun. In addition to saving time, stabilized tabs maximize chlorine and reduce costs.
Unstabilized Chlorine Tablets
As they cannot last as long as stabilized chlorine tablets, these tablets are best used in indoor swimming pools. Cyanuric acid is absent, so UV rays and the sun do not protect them, which causes them to burn faster. In general, unstabilized chlorine consists of lithium hypochlorite, sodium hypochlorite, and calcium hypochlorite.
Calcium hypochlorite, or cal-hypo, is the most commonly used chlorine for pools because it is safe and easy to use. It is also very effective, containing about 65% chlorine tablets for the swimming pool.
The unstabilized chlorine tabs often contain lithium hypochlorite or sodium hypochlorite. They are without stabilizers and dissolve faster in the swimming pool water.
Indoor pools requiring regular treatment to keep them clean and free of contaminants are ideal for unstabilized tablets. These tablets will provide results quickly.
How does chlorine work?
The key to using chlorine is to understand how it works. The best sanitizer is good ol’ inexpensive chlorine, but no one of the other tools does the job as well as it. Bacteria, viruses, and algae are all killed by the best chlorine!
When chlorine comes into contact with microorganisms and bacteria, it produces a chemical reaction. This chemical breaks down into several different substances, including hypochlorous acid (HOCI), which destroys the cells that produce unwanted pests.
The process is known as oxidation, so some pool owners add more oxidizers to their water when they use chemicals that don’t work well. If the chemistry of the pool is balanced, the chlorine will do its job.
In other words, for chlorine to properly protect you, all pool chemicals’ water parameters must be within the normal range, including pH, alkalinity, cyanuric acid, calcium hardness, and chlorine.
- pH: 7.4 – 7.6
- Chlorine: 1.0 – 3.0 ppm
- Total alkalinity: 80 – 140 ppm
- Calcium hardness: 200 – 400
- Cyanuric acid: 25 – 50 ppm
How to add Chlorine Tablets to Your Pool?
When you choose the best chlorine tablets, it’s time to do the next step. Add chlorine tablet for your pool. There are a few steps involved in adding chlorine to a pool. To add chlorine, follow these steps:
Automatic chlorine dispensers
The automatic pool chlorinator is a chlorine feeder that offers convenience and the highest level of efficiency when it comes to distributing chlorine. When pool owners want to dispense chlorine tablets that have the right chemical balance, the chlorinator is an excellent choice.
To avoid over-chlorination of your swimming pool, you can use this method to control the process. The automatic chlorinator should be filled with chlorine tablets and the level should be set between 1 and 3 parts per million. Check the chlorine levels with test strips to make sure they are appropriate for your pool use, pool water quality, and weather.
Floating Chlorine Dispensers
During the dissolved time, the chlorine tablets for swimming pools inside floating dispensers sanitize your pool while protecting it. Despite its ease of use and low maintenance, this method is often unsuitable for pools with liners.
It is possible for the chlorine tablets to get stuck in an area of the pool, causing too much chlorine to be dispensed in a concentrated area damaging your pool liner. Additionally, chlorine tablet is distributed unevenly if the swimming pool water circulation is not adequate.
Alternatively, you can directly add the tablets to the pool skimmer. During the running of the filter, water passes through the skimmer basket, dissolving the tablets. A return jet then pushes the chlorinated pool water evenly into your pool.
Nevertheless, the disadvantage of this method is that even when the filter isn’t running, the tabs keep dissolving. Unattended, the pool water will be highly chlorinated and corrosive.
How many chlorine tablets per week?
It is actually quite straightforward to determine how many chlorine tablets to add to your pool.
3″ and 2″ tablets are applied once per week for 5,000 gallons. An example would be to administer two tablets each week to a 10,000-gallon pool.
Take for instance a pool that holds 8,000 or 12,000 gallons. Just round it up.
8,000 gallons = 2 tablets per week.
12.000 gallons pool = 3 tablets per week.
You should definitely check with the manufacturer of the tablets you choose for your swimming pool.
