Whether you own a pool as a business or you own yours for relaxation purposes, we know you need the proper knowledge about how much liquid chlorine to shock pool areas.
This is why we have put this article together to discuss fantastic topics about the subject matter.
Liquid Chlorine vs. Bleach in Shocking of Pool
It is essential to point out that the same amount of base chemical a bleach carries is the same as that of the pool chlorine. The chemical in question is chlorine. What distinguishes the liquid chlorine and bleach, however, is the strength of their concentration levels.
Whenever there is the liquid chlorine vs. bleach discussion, it is also worth noting that both contain the “Sodium Hypochlorite,” which puts them in the same bracket regarding water purification.
What differs majorly between the two is that bleach is commonly at a more diluted level and will need a lot of it to be put in the pool to bring about the same effectiveness. This is not the same with the usage or application of liquid chlorine.
Comparison between liquid chlorine and bleach
| Liquid Chlorine | Bleach |
| Consists of 65% calcium hypochlorite and other inert ingredients | Bleach is made of sodium hypochlorite, which is essentially chlorine in its liquid form |
| Relatively stronger and proves to be more effective | Not as strong as liquid chlorine and requires having more on-demand |
| Contains a stabilizer, thus holds up a bit longer | Does not contain a stabilizer and will require putting quite a bit more into your pool |
| Quite expensive and not as easier to find | Very affordable and can be easily bought from stores near you |
Note that it is not just the liquid chlorine or the bleach that can be used to shock or sanitize your pool. They are just two ways among others you can consider in shocking the pool. You can also use salt and chlorine tablets to sanitize and clean your pool to give it a refreshing look and a healthy touch on your body or that of any of your family members or guests.
If you use liquid chlorine vs. bleach, be rest assured that either of them can be used according to the importance of need at any given time.
The bleach is cheap and usually sold at pocket-friendly prices. It can be bought with a few bucks when compared to liquid chlorine. It is also easy to find.
You may also want to consider the liquid chlorine instead of bleach due to its concentration. Bleach is around 6% sodium hypochlorite.
Shock Pool With Algae
You do not want to see the full extent of damage algae can cause to your swimming pool. The dull appearance and the astronomical drop in chlorine concentration within the pool become even quicker with algae.
Algae consist of a wide range of eukaryotic, phototrophic, and oxygenic microorganisms that use energy and light as a source of growth. Algae is different from plants because they (algae) do not possess any tissue differentiation.
Any pool with algae is an eyesore and very much dangerous to health. That is why it is crucial to act fast whenever they are perceived to be within the swimming pool.
However, just a dose of fresh chlorine can eliminate this inimical threat to your pool’s survival.
These are the main types of algae: Blue-Green Algae (considered the worst type of algae), green pond algae, filamentous/string/hair algae, bryozoans, diatoms, red pond algae, chara/muskgrass, golden algae.
Tips To Combat Algae In Your Pool
If you want to combat the algae issues in the pool adequately, you need to be thorough with the treatment of the pool.
- Constantly use the doses of medicine appropriately and at the right time for maximum effectiveness; if not, all your efforts will be wasted.
- Brush the whole pool, especially areas with visible signs of algae. The brushing process may be done only on the first day of treatment.
- Regularly look into the filter pressure to clean as the need may arise.
Safety Tips
- Ensure a thorough check on the lighting niches, the plumbing area, and under the ladder. These are places where algae could hide and develop with the knowledge of the pool owner.
- Maintain a high and continuous chlorine level to wipe out the algae completely.
To kill algae, you need to shock the pool ideally with Liquid Chlorine of up to 1.5L per 10,000L. The least amount of chlorine required to destroy the algae is 30 Parts Per Million (PPM).
How Much Liquid Chlorine Needed for 20000-gallon Pool
The general and ideal measure of the pool water balance against chlorine is always expected to be between the range of 1 to 3 Parts Per Million (PPM).
It implies that whether for a 20000-gallon pool, for 15000-gallon pool, or a 10000-gallon pool, you will be required to have chlorine of about 0.00013 ounces per gallon of pool water.
You will also need to calculate the amount of chlorine required to chlorinate your swimming pool super since different pools have various kinds of sizes.
Since most of the products you will purchase at the store will be mostly best suited for the swimming pool with the 10,000 gallons of pool water capacity, it simply means for a 20000-gallon pool; you will buy a double of the products.
Doing this is just the wisest and most rational decision to make. You will not need to rack your brain and disturb yourself about calculations on the amount of liquid chlorine to use for this kind of large pool.
Just in case you are feeling or getting confused, follow the instructions on the product on how much liquid chlorine to add to raise the treatment level to your taste, especially to the volume of pool water available to you. It would be best if you did this after calculating the size of the pool, as this will help determine the number of gallons it contains.
As a pool owner, it is very significant for you to know and understand the chlorinating process, as it is crucial in pool maintenance. You need to update yourself to catch up with the latest trends constantly.
How Much Liquid Chlorine Needed for a 15000-gallon pool
As stated earlier, all that matters is calculating the pool’s size to determine the amount of gallon of water the pool can contain.
The amount of liquid chlorine needed for the 15000-gallon pool will fall in between the amount of liquid chlorine required for the 10000-gallon pool and the amount necessary for the 20000-gallon pool.
Averagely, any standard round ring pool is ideally 5 feet wide and 48 inches in its height. Such a round ring pool will conveniently contain about 4,978 gallons of water. However, an in-ground pool should carry above 31,000 gallons of water.
To calculate the number of gallons a swimming pool has, we need to measure and multiply the breadth, length, and average depth and multiply the resultant value by 7.5 for a rectangular pool, 6.7 for an oval 5.9 for around the pool.
Note that it is proper for you to apply liquid chlorine for a 15000-gallon pool when the pool water temperature is raised because organisms and bacteria could easily thrive in warm water.
You can also keep your 15-000 gallon pool at a relaxed level of between 86 to 88 °F. However, if there are a couple of swimmers, the temperature level can be reduced to a range of 78 to 84 °F. If you need to measure the pool temperature, there is a pool thermometer for you to do that.
The liquid chlorine can also be applied when the free chlorine Level Goes Below 3 ppm. If you realize that the free chlorine level is less than 3 ppm, then the time is right to shock your pool.
Application of the liquid chlorine can also take place after heavy rains and during prolonged seasons of hot weather.
How Much Liquid Chlorine Needed for 10000-gallon Pool
It is generally recommended for any pool owner of a 10000-gallon pool to use a single pound of calcium hypo for its shocking. Also, sodium hypo of 10 ounces alongside approximately 12.5% chlorine is required to sanitize your pool.
While observing and executing all these, ensure the pool water is at its standard temperate level. Also, ensure the pool’s pH falls between 7.2 and 7.6 while maintaining its alkalinity between 80 and 120 ppm.
The maintenance level is not the same for a 10000-gallon pool, whether a chlorine-based pool or a saltwater pool. The chlorine-based pool requires more maintenance than the saltwater ones.
Generally, whether for a 10000-gallon pool or whatever category of the pool, the saltwater pool does not need much treatment. The exception to this is an influx of algae or the contamination of the saltwater pool by soil, oil, or other liquid contaminants.
The reason for this is not far-fetched. Saltwater pools use chlorine generators to produce a chlorine compound, which is almost like the chlorine present in shock treatments.
Meanwhile, the best usage option regarding the saltwater pool system is the Sodium Hypochlorite liquid chlorine, as it helps to enhance chlorine levels in the pool water. You can use it in treating your hot tubs and spas as well.
Once used in a hot tub or swimming pool, it is instantaneously ready to erase viruses, bacteria, algae, and any other microorganisms present within the water due to its quick and rapid action.
Helpful Questions And Answers
Does Liquid Chlorine Raise PH?
A: No. It does not raise pH. When dissolved in water, liquid chlorine enables Hypochlorous (HOCI) acid and Sodium hydroxide (NaOH), which helps the level rise. However, when the Hypochlorous is deflated by UV, it births hydrochloric acid (HCI). The rate of this HCl is almost the same as the amount of NaOH; therefore, any net effect on pH is nearly nothing or completely zero.
Will Liquid Chlorine Clear a Green Pool?
Definitely, the liquid chlorine can clear a green pool, but the amount of shock needed to do that depends on the pool’s level of dirtiness.
The process will be done for several days before the water is clean enough. However, have it at the back of your mind that you cannot over shock a pool.
Is it Better to Use Liquid Chlorine or Tablets?
Deciding on whether you should go for the chlorine tablets or the liquid chlorine pool sanitizers depends on the purpose you are going for it.
Chlorine tablets are advisable for anyone seeking convenience. They are also cost-effective. The liquid chlorine is costlier but very effective when it comes to rapid response.
How Often Should I Add Liquid Chlorine to my Pool?
To know your consumption level, you will have to wait for a week or two. For hot and sunny temperatures, the 65 CYA is moderate enough.
Just ensure you add enough liquid chlorine to keep the FC over the minimum level for your CYA level pending the time you can add more. You can make use of the pool calculator too.
1 Gallon of Liquid Shock Equals How Many Pounds?
The weight of one gallon of chlorine bleach is 8.375 pounds
How Long After Adding Liquid Chlorine Can You Swim?
This usually not less than 8 hours for shock treatments done with chlorine. To gain entrance into the swimming pool to swim again, you will have to wait until the amount of time recommended on the package’s instructions is reached.
You are advised not to enter the swimming pool until the chlorine levels have gone below 3 ppm.
Where to Buy Liquid Chlorine For Swimming Pool?
Across the United States, you can purchase the liquid chlorine on Walmart and SamsClub. Other locations to look out for this product within the US include Alabama, Alaska, and Arizona.
You can also check for a local HASA dealer into the general sales of bulk liquid chlorine, even at a reasonable price. Some other locations are Arkansas, California, and Connecticut.
Wrapping Things Up
To achieve the desirable aim to shock pool with liquid chlorine, you need to understand the whole process’s dynamics. The calculation of the size of the pool water is essential. The cost and effectiveness of the liquid chlorine are high, and the consistent treatment of the pool water is highly determinant to the health and well-being of swimmers.
