Bleach In Pool Calculator
To calculate the right amount of bleach needed in your pool, you will need to know the volume of water in your pool and also the level of chlorine.
Calculating the pool volume
Pool Volume;= Length x Width x Average depth of the pool
Once you have calculated the volume, multiply the figure by the follows:
5.9 if its around pool;
6.7 if its an oval pool
7.5 if its a rectangular pool
What you get is the number of gallons in your swimming pool
The ideal level of chlorine in a pool should be 1-3PPM for effective sanitization of the pool. Levels that are higher than this are not safe for swimmers.
You can use any of the following tools to test your pool water
Test strips: This can test up to 7 parameters: In addition to testing free and total chlorine levels it also tests total hardness, bromine, pH, cyanuric acid & total alkalinity
An electro-tester-Checks and monitors chlorine levels. It can also be used for routine monitoring of pH in spas and different water sources.
How Much Bleach To Add
So how much bleach per gallon pool? For that, you must first know how much bleach is actually required. This is determined by testing the chlorine level of the water. Get yourself a chlorine testing kit for that.
The ideal chlorine level is between 1 to 2 ppm. This ensures the water is free from contamination and safe for the swimmers.
To calculate how much bleach you need for shocking your pool, use half-gallon of bleach per 10,000 gallons of water for raising the chlorine levels by 5 ppm.; If you want to raise the chlorine level by 2.5 ppm, ¼ gallon of bleach per 10,000 gallons of water should be enough. Do the math to calculate how much ppm is required for your pool and go from there. Keep testing the water for chlorine levels in between.

How To Add Chlorine Tablets To Your Swimming Pool
Finally, the most important part of this post how to add chlorine tablets to your swimming pool.
What do you mean how to add, why cant you just throw them in the water? Thats what theyre made for.
Great point. Yes, chlorine tablets are designed to go in your water. However, theyre not mean to be left dissolving on the floor of your pool.
Why?
Leaving chlorine tablets on the bottom of your pool can cause permanent staining and bleach liners. Its also the least effective way to use them.
Tablets sitting at the bottom of your pool are nowhere near your pools skimmer line. So they dissolve slower and release sanitizer unevenly. When you use chlorine tablets this way, most of the chlorine gets wasted, and you end up having to use even more.
So instead of doing that, here are 4 much better ways to add chlorine tablets to your swimming pool.
Youve probably seen this classic pool accessory a few times. You may already be using one now.
Theyre the small plastic containers that float on the surface of your water. Sometimes they have funny looking duck or animal on top, other times theyre blue and look like the one in the picture above.
The beauty of floating dispensers lies in their simplicity. They hold just a few tablets and keep them safely contained to gradually dissolve. As the dispenser floats across the surface of your pool, it releases chlorine into your water.
What Type Of Chlorine Is Best To Use
Besides knowing how much chlorine to put in water storage tank, you also need to decide on which type of chlorine to use.
There are three main types of bleach available to use to sanitize your water storage tank.
The worst option is to use household laundry bleach, Clorox. This contains unwanted chemicals besides chlorine.; Laundry bleach does work and will disinfect your storage tank, so that is an option.; ;Make sure to use non-scented.
The best chlorine bleach that is certified for drinking water.; If you cannot find liquid bleach that is NSF certified you can use dry NSF pellets or powdered bleach.
A second good option is to use liquid pool chlorine, which is sodium hypochlorite without additives . You can usually find liquid pool chlorine at Home Depot or Lowes or hardware stores and also spa and pool supply companies.; Pool chlorine is liquid 10-12% sodium hypochlorite, which means it has 10 to 12% chlorine.
An easy-to-use NSF-certified chlorine bleach is chlorine granules with no additives.; This type is calcium hypochlorite and can be mixed with warm water and put into storage tank.
Do not use dry powdered pool chlorine, sometimes known as Tri-Chlor in your storage tank or well water.;;

Pool Shock: When & How Much
Welcome to our discussion on swimming pool shock,; specifically, when should one shock the pool, and how much do I need to add?
Shocking the pool with chlorine is the raising of free chlorine levels in the pool to such a high level that every living thing in the water is killed by cell disruption. I liken the process to a lightning bolt ripping through the water, and perhaps thats why its called shocking the pool.
Dont Wait Shock Your Pool Now
Most people prefer to use bleach for pools instead of chlorine for shocking. This is because it dissolves properly and does not include any fillers usually found in chlorine products. There are two ways to add bleach to your pool; this is either with the use of a liquidator or doing it manually.;
You can use liquid bleach to shock your pool, and it also clears your pool water. One mistake most people make when shocking their pools is not using the right quantity of bleach. It should not be less, and it shouldnt be added in excess. If you apply it perfectly to your pool water, it makes your pool safe for swimming.;
It is important to test your pools chlorine level before applying bleach and measure the pool water volume. Follow this process and you wont have any safety issues with your swimming pool.

Why Add Bleach To Your Pool
Bleach is commonly used for laundry in homes and serves to remove tough stains on clothes. You also need chlorine and bleach to do the same thing in your pool these two agents are an essential part of pool maintenance.
The hypochlorous acid released by the bleach in your pool kills all the contaminants in it. Although very little bleach is needed when removing stains on clothes, youll need a little more when treating your pool to get the same effect chlorine gives. Avoid using scented bleach for your pool as this only adds to the contaminants.
Weekly Chlorine Dose For The Swimming Pool
Once the chlorine value is at the right level, you can keep it at that level with chlorine tablets. Chlorine tablets are better than chlorine granules because the tablets dissolve slowly and keep the chlorine value constant.
Unfortunately, it is not easy to say how many chlorine tablets you should add to the swimming pool or how often you need to add them. The chlorine tablet dosage does not depend solely on the volume of the swimming pool. A lot of other things also play a role, such as:
If the swimming pool isnt used much, be sure to check the water quality once a week using a water tester. If the pool is used more than 2 days a week, the water quality needs to be checked 2 to 3 times a week.
If the pH value is good, check whether the chlorine tablet has completely dissolved or not. Once the chlorine tablet has dissolved, it is best to add 1 chlorine tablet per skimmer. Use these chlorine tablets for this. For a small inflatable pool, it is best to use these 20 gram mini-chlorine tablets. You can add one of these per 3 m³ of water.

What Amount Of Chlorine Shock Do I Add In My Pool
Liquid chlorine or sodium hypochlorite is always around 12.5% chlorine. Regular bleach is less stronger compared to sodium hypochlorite and is always around 8%you will need to use a lot of it, as compared to sodium hypo.
For regular pool sanitization and clearing cloudy water, the right amount of liquid chlorine to add to your pool will depend on your pool size and the percentage of chlorine you are using. For instance, 10 fluid ounces of 12.5% HASA Sani-Clor or Chloro Guard will provide enough liquid chlorine to raise FC on 10,000 gallons of pool water by 1 ppm.
However, if you have severely cloudy pool water with the following signswon’t clear easily after adding a lot of chlorine, high combined chlorine levels , or very low free chlorine and cyanuric acid levelsyou might be having ammonia in your pool, and you need extra work to clear stubborn cloudy pool water caused by ammonia.
For algae treatment, I always recommend using calcium hypochlorite, which is stronger and always comes with around 60% chlorine concentration. To kill algae, you need to triple shock your swimming pool using calcium hypo. For instance, for sanitising a pool using cal hypo , 1 pound of In The Swim cal hypo should work for a 10,000-gallon pool. As such, since you need to triple shock the pool in case of algae breakout, you will need 3 pounds of calcium hypochlorite chlorine shock to kill green, black, and yellow algae in a 10,000-gallon pool.
The Number Of Hours You Use The Pool

The more swimming there is, the quicker the added chlorine degrades. For example, if you wear your swim cap&swimming goggles and get in the pool twice per week, you may need to add chlorine more often compared to someone who uses his or her pool once per week.;
If your swimming pool is not used much, you need to check the quality of the pool water once per week. If you use the pool more than 2 days per week, you should check the water quality 2 3 times every week.;
