Ready to dive in?
How Much Bleach Should You Use
The amount of chlorine you need in your pool depends on several factors, including the size of your pool, your cyanuric acid level, and how quickly your chlorine is used up from the sun and contaminants.
As you can see on this chart provided by Trouble Free Pool, the higher your CYA level, the higher your FC ppm should be.
Continue to test your water regularly to make sure that your pool chemistry is keeping on track. An example of a good pool water test kit is the Taylor K-2006.;
Once in a while, you may end up getting a splash of bleach on your hands, here are our tips on how to get rid of the smell.
When Do You Need To Shock A Pool
When your pool has cloudy or green water, that means that the level of chlorine in the pool is too low and that it has fallen below the recommended value which is 1 ppm . ;This usually happens when chlorine has formed chloramines, which with bacteria and other contaminants is no longer available for sanitizing. Chloramines can emit an odor, so regardless of the fact that the concentration of free chlorine is low, the pool may actually smell of chlorine.

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.
How Often Should I Put Bleach In My Pool
It will help if you put bleach in your pool as often as your chlorine testing kit shows that the chlorine ppm level is low.
However, beyond this, you will need bleach when:;
- Your pool has been in use for a very long time without any maintenance

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.;

How Much Bleach Per Gallon Of Pool Water
Before you begin the bleaching process, the first step is to know what quantity of bleach to apply in your pool water. The standard measurement is to add a quarter teaspoon or sixteen drops of bleach per gallon of pool water.
However, if your pool water has a cloudy surface, you can make it a one-eighth teaspoon of bleach, so the water clears.
With this calculation, you can easily know how much bleach you will need when applying it in 10,000-gallon pool water. A pool holding 10,000 gallons of water will require at least half a gallon of bleach to raise the chlorine level to 5ppm. To get your pools chlorine level to be at 2.5ppm, use a quarter of the gallon of bleach.
Though, ensure you get the current chlorine level by testing your pool before applying any quantity of bleach.;

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 Â¼ gallon of bleach per 10,000 gallons of water. Use this basic math to figure out how much ppm you have to raise your pool by and go from there. Make sure to continually test the pool water.
Should You Use Clorox Instead Of Pool Chlorine
Household bleaches such as Clorox are effective sanitizers for your pool and you can use it. However you need to be very careful not to purchase bleaches with fragrances, colors and other additives that could cause big issues in your 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.
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 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 pools survival.

How To Calculate How Many Gallons Your Pool Has
If you dont know how many gallons your swimming pool has, just use the basic formula that well give you. The formula for calculating a pool area in square feet or meters is the following:
- Length x width x depth x 7.5 = volume
By multiplying the length of the pool with width and depth gives the volume in cubic feet. Since each cubic foot has 7.5 gallons of water, multiply the cubic feet of the pool by 7.5 and you will get the volume of the pool in gallons.
If you have a round pool, then you need to multiply the volume of the pool by 5.9. For the oval pool, you need to multiply it by 6.7. I hope that you know now how to calculate the pool gallons.

How Does Chlorine Work To Sanitize The Pool
There is a chemical reaction that occurs when chlorine dissolves in water. This reaction releases hypochlorous acid and hypochlorite ions, which oxidize the microorganisms and bacteria in the water.
It does this by attacking the lipids in the cell walls and destroying the enzymes and structures inside the cell. This process renders the microorganisms and bacteria harmless.

Tips On How To Use Chlorine Or Bleach For Your Pool
Adding chlorine or bleach to your pool is easy, so long as you know the basics of your pool and follow the instructions. Also, make sure that your pool is clean, as chlorine or bleach wont do its job as well if the pool has soiled surfaces.
When adding chlorine, it depends on the type you are using. Sprinkle the recommended amount of chlorine to your pool, spreading it around. But before that, you should create the solution, whether you are using liquid or powdered form.
When using a chlorine mix , wait half an hour before you use it. Also, use the chlorine when there is no direct sunlight. Solutions like these lose strength and power over time, so we recommend you to create a batch just right for one use, or to use it immediately.
If using bleach, all you need to do is to use 1/8 cup for every 100 gallons of water. Its best to pour it with a skimmer to avoid the harsh chemicals from harming your skin while swimming.
Popular brand names such as Clorox are recommended to use, as they have the powerful ingredients to disinfect your pool. It wont be as effective as chlorine, but it does a good job.
Its best to disinfect your pool daily , once every few days. That way, your pool will stay clean and you can swim in it without worry of harm from bacteria and germs lurking in your pool.
Dpd Powder Chlorine Test
There are a number of ways to test your water chlorine levels including test strips and dropper bottles, however the more accurate and the way I recommend; testing it is with a DPD powder test kit.
When you use this testing method, you will be able to get your chlorine level accuracy within .5 or .2 ppm depending on the amount of water used during the test.; It is much more difficult to get that accurate of a reading when trying to depend on the human eye to match colors in determining the levels.
