It is easy to purchase chlorine tablets online or from your local pool supply store.

One of the most significant challenges is knowing how much water your swimming pool holds. You need to know this to know how much chlorine to add. Measure your pool’s length and width and then take the average depth.

  1. Multiply the length x width x the average depth.
  2. For a circular pool, measure the diameter, and divide the value by 2.
  3. To calculate the radius, use the formula πr2h. R is the radius, and h is your average pool depth.
  4. For instance, if your pool is 50 ft × 20 ft and the shallow end is 3 ft with the deep end being 6 ft, your average depth is 4.5 ft.
  5. Once you have this, multiply 50 × 20 × 4.5 ft to find a volume of 4500 cubic feet.
  6. Since 1 cubic foot contains 7.48 gallons of water, your pool holds 33,760 gallons of water.

Before you add, you need to know how much chlorine in a pool there is. Test the pool water to find out how much chlorine you have to add.

Before adding chlorine, carry out a pH level test and the chemical levels using your pool water test kit. (Find the Best Solar Pool Cover)

Read the instructions, and the label will advise how much to add based on the volume of your pool to reach the target chlorine level in the correct ppm.

Round up to the nearest 5,000 gallons. For instance, suppose you have 33,760 gallons of water in your pool, your current chlorine level would be around 0 ppm.

Suppose your product advises adding 1 tablet per 5,000 gallons to raise chlorine levels by 1 ppm. You’ll use a dose of 14 tablets to reach a level of 2 ppm.

To make things easier, you can use a chlorine dispenser because adding tablets to your pool doesn’t work. Rather, the best way is to use a floating chlorine feeder or skimmer. All it takes is to add tablets to the feeder cartridge and let them dissolve.

You may need to add cyanuric acid if you don’t have a stabilized chlorine product. This is a stabilizer used to make chlorine last longer. If chlorine is labeled as stabilized, trichlor, or dichlor, it contains this acid already.

If you need to purchase, you’ll need to add about 4 pounds of cyanuric acid per 10,000 gallons of water. This will reach a level of 10 ppm. It is advisable to keep cyanuric acid levels about 50 ppm.

Tablets are best for routine chlorination, and shock treatments come in liquid or granular chlorine forms. The desired amounts will vary, so read the instructions carefully.

  • Typically, you’ll need 3.5 US quarts of liquid shock treatment or 1 pound of granular product per 10,000 gallons of water.
  • Check the instructions to find the amount needed to deliver a 1 ppm change in your chlorine levels. The ideal is to bring free available chlorine to a minimum of 8 ppm.
  • Mix with warm water if it needs to be dissolved. Fill a large bucket with warm water as on the instructions.
  • Add recommended chemical amount, then mix until a liquid is evenly dispersed or the granular product has dissolved.

Before swimming, wait until chlorine levels have dropped to 5 parts per million. Shock treatments raise free usable chlorine levels to 8 to 10 ppm, higher than the healthy swimming range.

Some shock treatments are effective, and you can swim after 15 to 20 minutes. In most cases, you need to wait 4 to 24 hours.

What is the Best Way to Add Chlorine to a Pool?

Since it kills bacteria and viruses, chlorine is an essential pool additive. It comes in four different forms: tablets, sticks, granules, and liquid.

  2. Stir in the granular chlorine and water and make sure not to breathe chlorine vapors.
  3. Turn on your pump as you want to circulate the chlorine to settle at the bottom of the pool. Remove the skimmer cover and pour your liquid into the skimmer.
  4. Let the pool circulate for a couple of hours before swimming as it lets the chlorine disperse in plenty of time.

If you are adding chlorine granules into your skimmer, you can do so with these steps
