How Many Chlorine Tablets for 10ft Pool?

One of the best ways to make your pool attractive is to maintain its safety and cleanliness. To constantly achieve this, you need to ensure that you use the right amount of chlorine tablets. But the real question is, what amount is suitable for a 10ft pool?

Generally, the quick way to know the right number of chlorine tablets for a pool is to round its volume up to the closest 5,000 capacity in gallons. Since a 10ft pool has a water capacity of 1,052 gallons, all needed is one tablet.

What are Chlorine Tablets?

Chlorine tablets are water disinfectants composed of stabilizers and ideal for outdoor pools. Being in a solid dosage form, chlorine tablets will dissolve slowly when placed in the pool to maintain the pool’s chlorine levels. Are these tablets safe? Yes, they are. They are also cost-effective and impressively potent. If your pool needs proper sanitization, they are the right solution.

Chlorine Tablet Types

Chlorine tablets are in different sizes and ingredients. There are stabilized chlorine and unstabilized chlorine. You should know that the unstabilized chlorine is without cyanuric acid (CYA), which lowers how effective it is and makes it burn away when exposed to the sun. When choosing a chlorine tablet type, you must ensure that it’s safe for you, your family, and /or friends. Below are the two types of chlorine tablets:

  1. 1-inch Tablets: The level of chlorine in 1-inch tables is less compared to 3-inch tablets, but the tablets dissolve faster. With this, the tablets are ideal for smaller indoor pools and spas.
  2. 3-inch Tablets: These tablets contain a higher level of chlorine compared to 1-inch tablets. With this, they are ideal for commercial spas and pools. They are cost-effective and user-friendly. Besides, users will only need a few of them in their pools.

How Do Chlorine Tablets Work?

The chemical compound in chlorine tablets is called Trichloro-S-Triazinetrione. This active component ensures that chlorine is more efficient. How the tablets dissolve is determined by the time they stay in the water.

To achieve perfect pool chlorination, you must allow the tablets to disperse evenly. With chlorine tablets, you can be assured of clean pool water (without algae or bacteria).

What Number of Chlorine Tablets do you need for10ft Pool?

Pools are in different sizes, and each size has a specific water capacity and a suitable number of chlorine tablets to use. Do you have a 10ft pool but need to be sure of the right amount of chlorine tablets to apply? You should understand that the use of chlorine tablets is an ideal way to be sure of the right pool chlorine levels. Running high levels of stabilizer, which can affect the pool surfaces and equipment, can easily be reduced if you know the required number of tablets for your pool.

So, how many chlorine tablets should you place in your pool at a time? The answer to this question will depend on the pool’s water capacity. Knowing the water capacity will make doing the math easier, allowing you to get an accurate number. After knowing your pool’s water capacity, round it up to the nearest 5,000 capacity (for every 5000 capacity, you need one tablet; if you have about 20,000 capacity, the required number of tablets will be 4).

Research shows that the water capacity of a 10ft pool is about 1,052 gallons. In this situation, there is no need to break the tablet. All you need to do is put one tablet in the water and have it perfectly chlorinated.

Frequently Asked Questions (FAQs)

Below are some important questions you may want to review for further knowledge.

Where should the tablets be placed in the pool?

Inexperienced pool owners using chlorine tablets, probably for the first time, may think the right way to apply the tablets is to toss them directly into the pool and wait to see their work. This is absolutely wrong. Tossing the tablets directly into the pool will only make them settle on the bottom, causing stains. However, to distribute the solid dosage evenly for perfect chlorination, you can use any of the following devices:

  1. Using automatic Chlorinator:  This device helps disperse chlorine tablets in your pool in their accurate amounts. It’s designed with a tablet-feeding spot and a knob for control to set the ppm level.

This chlorinator is in two different ways (automatic and off-line chlorinators). The automatic type is made for a permanent installation, while the off-line type is used when it’s impossible to fix an in-line chlorinator into the existing system. Automatic chlorinators can be expensive, but users can control the feed rate through them.

  • Using floating chlorine dispenser: This device is very easy to use. It’s a plastic tool that helps disperse the chlorine into the pool as it moves around on the water’s surface.

The downside of this plastic gadget is that it may, at times, distribute the chlorine unevenly by sticking in the pool or becoming entangled with the skimmer. With this, the pool liner can get stained, and the pool material can become corroded.

  • Using pool skimmer: This is a straightforward process. Get your chlorine tablets and place them on the skimmer’s mouth. The tablets will be dissolved by the water flowing into the pool skimmer. The chlorine is passed into the filter and then distributed evenly as the water moves back through the return jets.

After how long should my tablet be added to my pool?

The complete dissolution of chlorine tablets typically takes some days, determined by how you dispense them and the pool’s temperature. After application, the tablet will only last about three to five days before another chlorination.


It’s great to chlorinate your pool from time to time. Through this, you can enjoy safe and clean water. Since there are different pool types with unique sizes, it’s essential to know the number of chlorine tablets to apply to avoid too much chlorine, which can have several health implications such as eye irritation, coughing, rashes, throat/ nose pain, etc.
