How Much Bleach To Add To Kiddie Pool

Using Bleach After A Rain Storm For Pool

If you only have a kiddie pool, or you are probably planning to build a kiddie pool, the trick on counting how much bleach to use in the pool is similar. The thumb rule is to count the volume of water you are entering the pool.

Lets say your kiddie pool is a circular one with a diameter of 4 ft and 2 ft depth. The counting will be 3.14 x 42 x 2: 4 = 25.12 ft cubic. Then, to turn it into volume in gallons, multiply that number by 7.48 hence, it is ~188 gallons.

To count how much bleach you need to add, remember that bleach measurement: 1/8 cups of bleach per 100 gallons of water. To ease your counting, you can round 188 gallons to 200 gallons, which means youll need two times from 1/8 cups, which is ¼ cups of bleach.

Adding Clorox Bleach To My Pool Things To Know

So, how much bleach to add to the pool? The first thing you need to know before adding a Clorox bleach is the size of the pool and what is the chlorine levels of the pool. The best way to measure it is to get a Chlorine Testing Pool kit. The preferred chlorine level for the pool is around 1.0 to 3.0 ppm , so the water is safe for everyone who wants to take a swim. Once you do the chlorine level test, you must know how many gallons your pool has so you can add the exact amount of bleach to it.

Note! Clorox Bleach is the same stuff as Liquid Chlorine just weaker by product weight.

Here is the great Youtube video where it is shown the process of adding Clorox bleach to the pool.

Whats The Proper Way To Add Bleach To Your Pool

The best way to add bleach to your pool is to do so by mixing it with some water first and then pouring it into your pool over the course of several minutes. While youre adding bleach, make sure to test the chlorine levels of the pool using a chlorine test kit. This way, youll ensure that you dont need to worry about over-chlorinating your pool.

After that, you will need to use a small amount of stabilizing agent to ensure that your bleach doesnt become too much for the pool water to handle. You can pick this up at the local pool supply store.

How Much Bleach For 1000 Gallon Pool

Typically, the amount of chlorine to add to your pool water, especially if it rounds up to 5000 gallons, is 3 ounces. Are you wondering how much bleach for 5000 gallon pool? For a pool holding 5000 gallons of water, use 20 ounces of bleach.

However, for a 1000 gallon pool of water, you wont need as much bleach as we already calculated for a 10,000 and 5,000-gallon pool.

Shocking your 1000 gallon pool will require a 1/20 gallon of bleach to get your pools chlorine level to 5ppm. Youll need a fraction of that amount which is 1/25 gallons of bleach, to raise the chlorine level to 2.5ppm.

How Much Bleach to Add to a Pool to Make Swimming Safe?

Adjust sliders to calculate the amount of bleach or chlorine to raise free chlorine levels in the pool.

Chlorine is the most popular disinfectant for swimming pools. There are three main measurements for chlorine, Free Chlorine , Combined Chlorine , and Total Chlorine . Free Chlorine is most commonly tested because it represents the amount of chlorine free in the water for disinfecting. Chlorine is very effective at eliminating most microorganisms in the water that cause disease, bacteria, and algae. Some parasites such as Cryptosporidium and Giardia are resistant to chlorine and need to be treated with UV or Ozone.


More About Pool Chlorine

Swimming pool chlorine levels should be tested daily or every other day if a chlorine generator is used. Chlorine is constantly being consumed by sunlight and contaminates. It is important not to let the Free Chlorine levels reach zero. Once Free Chlorine is zero, there is nothing to protect the pool water from microorganisms and other contaminants.

Hypochlorous Acid

Chemical Formula: HOCl

Hypochlorous acid plus Hypochlorite Ion is what’s referred to as “Free Chlorine.” HOCl is the active agent responsible for the oxidation of both organic and inorganic materials in chlorinated water. HOCl is formed when chlorine is dissolved in the water.

The formula is as follows:FC = HOCl + OCl-


Chemical Formula: NH2Cl

How To Raise Chlorine Level In Pool With Bleach

Bleach is quite effective in increasing the free Chlorine in an inexpensive way. You need to follow the below simple steps to raise your free Chlorine using a bleaching agent. Just make sure you are not using scented Bleach or specialized Bleach only use the original Bleach.

Follow the below simple steps to raise your pools chlorine levels with bleach:

Step 1: Check your pools pH level

Before adding Bleach to your pool, you need to check the water pH level. It is important because if the pH level is more than 7.8, your Chlorine will lose quickly

Step 2: Check the cyanuric acid level

Cyanuric acid is often called a pool conditioner or stabilizer. The chemical compound of Bleach is Sodium hypochlorite. After putting Bleach in your water, it will convert to sodium hypochlorite ions. When UV rays of sunlight hit, the chlorine parts will evaporate, which means you will need more Bleach, and lots of money will be wasted.

If there is enough Cyanuric Acid , it will create bonds with the sodium hypochlorite ions and it will protect the chlorine part from evaporation when sunlight hits. CYA should be between 30 ppm to 50 ppm. Otherwise, you need to add more CYA, if the ppm level is lower.

Step 3: Measuring your pool volume

You need to measure the volume of your pool water to determine the required amount of Bleach. You need to know the length, wide and deep of your pool to determine the pool water.

Step 4: Check the Existing Chlorine level

Step 5: Start Adding Bleach to the pool

How Much Liquid Bleach To Add To Pool

In general, liquid bleach usually contains around 5.25% 6.00% of sodium hypochlorite the active ingredient of bleach. The aforementioned counting was based on this, too, so you dont need to find the other resources again to count how much bleach to use in the pool. However, you may be confused about how much liquid bleach is equal to a cup.

A cup is equal to 240 milliliters. Hence, if you are talking about counting a hundred-gallon liquid bleach measurement, it will make 1/8 cup bleach equal 30 milliliters. For liquid measures, 30 milliliters equal to 2 tablespoons .

It is also important to remember that the higher the bleach concentration used, the littler the amount one should add to the swimming pool. The counting between chlorine granules, liquid bleach, and calcium hypochlorite to disinfect your swimming pool is also different.

Computing Amount Of Gallons In Your Pool

How Much Bleach To Put In Pool? (2021 Guideline ...

You need to compute the amount of water in your pool in order to ensure that you get the right measurement of bleach to use. How should you do that?

The volume of the pool = Length x Width x Average Depth of the Pool

After getting the volume, then multiply the volume by:

  • 7.5 for a rectangular pool.
  • 6.7 for an oval pool.
  • 5.9 for a-round pool.

The answer you will get is the number of gallons of water in your swimming pool . In our case, we choose a 1000 gallons pool.

Maintaining your swimming pool with bleach can involve two things: shocking your pool or raising the chlorine level.

  • When shocking your 1000 gallons pool, you need to use 0.05 gallons of bleach to take the chlorine level to 5 PPM.
  • If you simply want to raise the chlorine level, use 0.025 gallons of bleach to raise a 1000 gallons pool by 2.5 PPM.

Household Bleach Versus Pool

Traditional household bleach is a much weaker form of chlorine like that used in your pool. The biggest difference between household bleach and pool-grade chlorine is the strength of the chlorine in the solution. Household bleaches may also have other additives including fragrance, which is bad for your pool system. Pool-grade bleach is stronger and designed to stay in your water as long as possible, amplifying the sanitizing power of the chlorine.

If you use erosion tablets rather than liquid chlorine, these might contain other substances such as algaecides and something usually called dichlor or trichlor. Dichlor and trichlor are substances added to the erosion tablets that help the chlorine stabilize. This stabilizer can, at times, lead to problems. It can build up in your water over time, which can cause any chlorine added to the pool to bind with the stabilizer, making it unable to sterilize the water. This is why many pool experts recommend using simple pool-grade liquid chlorine and not these erosion pucks that have a ton of other additives in them.

  • 3″ Chlorine Tablets are slow-dissolving and stabilized
  • 8 oz. individually wrapped tablets in easy-open bags
  • 99% Trichloro-S-Triazinetrione
  • Perfect size for floaters or any automatic chlorine feeder

    How Much Bleach Should I Add To My Pool

    So, how much bleach to add to the pool? First, you need to know how much bleach to use. To do so, you need to know the chlorine levels of the pool. Get yourself a chlorine testing pool kit and follow the manufacturers instructions.

    You want to have a chlorine level of 1-3ppm so you can make sure that your water is safe for swimmers and free from contamination.

    Clorox is considered to be the most common bleach product that is used for pools. It has a 5.7% concentration, so if you have a 5,000-gallon pool, you will be using 3 cups or 24 oz to raise the chlorine levels.

    If you do not know how many gallons your pool holds, just multiply the length, , and finally and you will have an estimated volume. If you have a round pool multiply that volume by 5.9, if you have an oval pool multiply by 6.7 and for a rectangular pool multiply by 7.5 gallons. The final result will be an estimate of how much water your pool holds.

    If you need to calculate how much bleach or Clorox you need to shock your pool, you will have to use 1/2 gallon of bleach per 10,000 gallons of water to raise the chlorine levels by 5 ppm. If you are just trying to raise the chlorine level by 2.5 ppm, then you will have to use as much as a ¼ gallon of bleach per 10,000 gallons of water.
