How Much Shock For 1000 Gallon Pool

Rabail.waqar · August 15, 2021, 2:03pm

How much shock for a 1000 gallon pool? Just 0.13 ounces or slightly more may be required for a 1000-gallon pool. Instead of Clorox, I advise using ordinary liquid chlorine bleach or sodium hypochlorite for daily shocking. Clorox can only kill algae since it contains a much of calcium hypochlorite. Without any issues, your pool can function without a pump for a few days. However, keep in mind that a regular collection must be done at least once every 24 hours to prevent the growth of algae.

Why Shock The Pool?

While shocking your pool can address various concerns, we will concentrate on the three most significant ones here. A little quantity of pool shock is used to raise the chlorine level quickly. Super chlorination is the name for this method. Most of the time, just a pound of shock is enough to bring chlorine levels from zero to a safe level.

Algae

If this annoying thing is left to its own devices, it can do a lot of damage to your pool. Adding shock to your pool water will keep algae from growing. Shock is also the best way to eliminate algae that have grown and spread in your pool.

Bacteria

Like algae, bacteria is something you do not want in your pool water. Bacteria can damage the water in your pool, which means you may have to drain it. It can also make swimmers sick. Bacteria like cryptosporidium, E. coli, and giardia will not grow and will be killed by pool shock.

Chloramines

Chloramines, also called Combined Available Chlorine (CAC), are made when Free Available Chlorine (FAC) combines with dirt, rain, bodily fluids, pollution, and other contaminants. Even though there will always be some chloramines in swimming pools, there should not be too much. Again, pool shock is the best way to eliminate too much chloramine in your collection.

Summary

After shocking a swimming pool, the filter should run for at least 6 hours. So the filter has time to clean the water, and the shock has time to mix with the water thoroughly. If there is a lot of algae in the pool, the filter must run 24 hours to 7 days after shocking.

How Many Shocks Do I Need For My Pool?

Breakpoint chlorination is the amount of chlorine at which the bonds between molecules break. At this point, chloramines, algae, and pathogens are also taken out of the water, which is helpful. Most of the time, 30 ppm of chlorine is enough to bring order back to the pool. The table mentioned is how much pool shock you need to add to get the chlorine level above the breaking point, usually around 30 ppm. Based on 10,000 gallons of water, this chart is a quick guide:

Pool Shock Type	Increase by 10 ppm
Calcium Hypochlorite	1.3 lbs
Sodium Hypochlorite	3.5 qts
Lithium Hypchlorite	2.5 lbs
Dichlor	1.5 lbs

Using the table above as an example, to raise the levels by 30 ppm in a 20,000-gallon pool, 7.8 lbs of cal-hypo would need to be added. Before adding the shock to the pool, ensure the water is balanced, especially the pH, which should be between 7.2 and 7.6.

A pH between 7.8 and 8.2 can make up to half of your pool shock ineffective. Proper filtration and circulation are essential for shocking to work right. Pool shock can not do everything on its own. After treating the water, filter it to eliminate any remaining dirt.

How To Give Your Pool A Shock?

Shocking your pool is a pretty easy thing to do. But before you start shocking, it is essential to do the following items if the pool water is not ready, the shock work and solve the problem.

Pool Cleaning: If there are leaves and other organic matter on the floor and surface, the chlorine will kill these things instead of the ABC problem we are trying to fix.

Change the pH: When the pH level is high, chlorine moves very slowly. Water with a pH of 8.0 will convert to less than half of the added chlorine as hypochlorous acid. Before shocking, bring the pH down to 7.2.

Read the label: We have many kinds of pool shock, each with a different amount to use. Some pool shock needs to be mixed with water in a bucket to dissolve the granules and keep the pool surface from getting damaged.

Add the shock: Spread the chlorine granules over the pool surface while the pool pump runs. Make sure you do not get any on your clothes or the pool deck, and slowly add the shock to the surface. Do not shock your pool when the wind is strong.

Clean the pool: It helps spread out the chemicals and gets rid of the dust and film on the surface of your pool.

Destroy Chloramines

Even though it seems counterintuitive, if your pool has a strong chlorine smell, it probably has a lot of chloramine bonds and needs a good pool shock. With a DPD test kit, you can measure both Free Available Chlorine (FAC) and Total Available Chlorine (TAC) (TAC). Shock the pool to a level that is 100 times higher than the level of chloramine.

For example, if the chloramine level in your water is 0.3 ppm, you should add enough shock to bring it up to 30 ppm. Increasing the chlorine level in your pool will break the bonds between the chloramines and get rid of them.

Here is a chart showing how much shock to add to eliminate chloramines. Remember that this chart is based on the idea that the pH is suitable and the level of Cyanuric Acid (CYA) is low. If there is more stabilizer in the pool or the pH level is above 7.5, you need to add more shock.

Chloramine Level	Cal Hypo	Dichlor
0.1	15 oz	18 oz
0.3	45 oz	54 oz
0.5	75 oz	90 oz

Summary

The chlorine concentration in the water is kept at the appropriate level in both above-ground (ring) and in-ground (ground) swimming pools. It prevents the water from becoming contaminated with harmful microorganisms. The optimal chlorine concentration in water is between 1 and 3 parts per million (ppm), or 0.00013 ounces per gallon.

Frequently Asked Questions

People ask many questions about the gallon pool. We discussed a few of them below:

1 - I have a 1000-gallon pool; how much shock should I use?

Generally, you should add 1/2 ounce of chlorine per 500 gallons of water weekly. If you have a 1,000-gallon pool, you should only need one ounce per week to clean the water.

2 - Do you know how much pool shock I need?

The chlorine level should rise to 10.0ppm by adding 2 pounds of a shock to every 10,000 gallons. Chlor Brite or Power Powder Plus will work with different types of collections. After shocking the pool, wait at least two hours before applying an algaecide.

3 - How many liters of bleach do I need?

To clean a storage tank, mix one gallon of NSF-approved, unscented bleach (5.25 percent chlorine) per 1000 gallons of water in the tank (i.e., 1 gallon per 250 gallons of water). It gives a chlorine level of 50 parts per million (ppm).

4 - With chlorine tablets, can you swim in the pool?

If you use the pads, they could be in the water with you when you swim. Also, check the chlorine level to ensure the water is clean enough to swim in.

5 - Can chlorine be put in a small pool?

Shock your pool with a lot of chlorine, and do not let anyone use it until the chlorine level drops below 3ppm. One cup of bleach for one hundred gallons of water in your pool, or if you have a tiny inflatable pool, use one-fourth of a teaspoon of bleach for every ten gallons.

6 - When I open the pool, how much chlorine should I put in it?

When opening the pool, it is best to do two thrusts. To double the shock, add two pounds of chlorine for 10,000 liters of water (for chlorine systems). Before you add chlorine to the pool, you should put on safety goggles.

7 - Can chlorine and shock be used simultaneously in a swimming pool?

It is necessary to take advantage of both the cards and the shock. Without taps, the chlorine shock will leave the water quickly. The chlorine level is high enough to clean the water thoroughly.

8 - Is shock the same as liquid chlorine?

The fundamental difference between chlorine and other chemicals is not how it looks but whether it is stable or not. The same chemical is used to clean the pool in liquid chlorine and shock-absorbing powder. How you use them is what makes them different.

9 - Why do pools at night feel creepy?

Shock your pool late at night or after the sun has gone down to keep free chlorine in the water for longer. Ultraviolet (UV) rays from direct sunlight lower the amount of free chlorine by a significant amount, making daytime shocks useless.

10 - Does a new pool need to be shocked?

Every pool is unique, and shaking the water in a pool should not be done unless it is essential to algae, chloramines, or other toxins; clean hazy pool water; or fix other water-related issues. You can look for chloramines and sea algae but can not see bacteria and other pathogens.

11 - Does my pool need to be shaken every week?

We suggest shaking the pool once a week or at least once every two weeks to help keep the chemical balance of the water. The shock of the collection will happen more often the more you use the pool.

12 - Can you move a pool around too much?

If you are too scared to swim, you should wait. If you have a cover for your pool, take it off. The faster your water goes away, the more sun it gets. Technically, CYA says that it is inevitable that the free chlorine level will no longer rise to the shock level.

13 - When you swim, do you use a pool pump?

Even though most people believe that the water in a swimming pool is filtered every 24 hours, the pump does not have to stay on continuously. If your pool is constantly being used, you may need to run the pump for eight hours a day and often check the chemical balance and clarity of the water.

14 - Can I shock my pool with Clorox?

To add five ppm of chlorine to 10K gallons of water, use 0.5 gallons of Clorox. If you want to add 2.5 ppm of chlorine to 10,000 gallons of water, you would need 1/4 of the product.

15 - How long do you wait to swim in a pool after shocking it?

After you shock the pool, swimming is safe as soon as the chlorine level drops to 5 ppm or less. It might take anything from twenty-four hours to a couple of days, depending on the kind of shock administered and how much of it was administered.

Conclusion

A 1000-gallon pool might only need about 0.13 ounces or a little more. Then, you can use a pool calculator to figure out how much chlorine to add. You should always have three ppm of free chlorine. Algae will die if you add too much shock or shock to your pool. Adding too much surprise to your collection will reduce the water chemical balance. It is likely to do that whether you overstocked the pool or not. The pH will either go up or down depending on what you used.
