Chlorine Tabs for Pool Water
If you’re wondering how using chlorine tablets makes pool water safe, then keep reading because you’re about to find out…
First, let’s consider what’s in your oasis.
Aside from H2O, your swimming pool water probably has dead bugs, debris, sweat, urine, poop, and various body oils from swimmers. Gross, right?
The purpose of chlorine from chlorine tablets or liquid is to kill bacteria, algae, and other organisms living in the water, tiles, cracks, and crevices of your pool.
Second, you might also be wondering:
1. Is Chlorine in both forms the same chemical used in both underground and above-ground swimming pools?
Yes and No. Liquid Chlorine is generally only Chlorine.
Whereas, tabs contain various other chemicals depending on the brand – read the labels for more info.
2. What’s the best pool chlorine brand to buy?
For my pool, I prefer Clorox XTRA Blue tablets but there are a lot of choices and most are basically the same chemical and prices.
XTRA Blue seems to do a better job in my pool controlling algae with fewer tabs per week…
Follow a Regular Pool Maintenance Schedule
Without chlorine in your pool, bacteria and algae will take over and turn the water green and dangerous.
But this mess can be avoided with regular maintenance.
Here’s the plan:
This will help keep your pool chemistry results more accurate and will keep you from having to add excessive amounts of chlorine tablets at one time.
When testing your pool water, get the water sample 10 – 12 inches below the surface…
And another thing to note is to take the sample away from the pools water edge or up against the wall.
I know how easy it is to just reach down along the pool’s edge with the test tube but it’s not a good practice.
It’s insane how many different testing kits you can buy to keep track of your chlorine levels.
I recommend you buy a pool test kit that offers these three different types of test results:
- Free Available Chlorine – the free available chlorine is the amount of chlorine in the water available to sanitize. This chlorine test result is the most important.
- Combined Chlorine – the combined chlorine is something you don’t want too much of because it’s the measurement of negative compounds in the water. If this number is high there’s a sure indication the water in the swimming pool has enough free available chlorine.
- Total Chlorine – the total chlorine is the combination of free and combined results.
Your pool service schedule should include: testing chlorine and chemicals weekly, adding chlorine tablets or liquids as required, adding shock, running the pump, backwashing, cleaning the filters and brushing.
Effects of Low Chlorine Levels
When swimming pool water doesn’t have enough chlorine in it swimmers can become ill from the bacteria and algae that may be living in the water.
Adding chlorine to pool water with low chlorine may cause the water to turn cloudy. It’s a good practice to wait until the water clears up before entering it. The cloudiness is a reaction of the living organisms to the chlorine.
Effects of High Chlorine Levels
Too much chlorine in a swimming pool can get absorbed through the skin and cause sickness. It will also cause the eyes and nose to burn. A good sign that a pool has too much chlorine is a strong gaseous smell.
Caution! These indications can also mean enough chlorine but too much acid. The only way to know for sure is to test the pool water weekly and adjust your chemicals based on the results.

Best Pool Chlorine Brand
You’re just adding the same amount of chemicals at one time that’s how try Clorox now we all know all of us backyard pool owners know that when you add chlorine to your pool you also have to measure the pH the pH is simply a measurement of acidity the higher the number of the pH they around pH 14 that’s very basic the lower the pH numbers say around pH 1 or 2 that’s very acidic for example the oceans pH is about 8.1 slightly basic a can of coke about 3.5 very acidic your pool wants to be right around 7.4 that’s the optimum pH for sodium hypo chloride to work in order to keep it there you have to add either an acid or a base depending on what your pool pH is so you go to on a Saturday morning take a sample from your pool water find out the pH and your 500 it’s 9 pH 9 that’s way too high you’ve got to bring it down in order to bring the pH down you have to add an acid and there are two commonly used assets in pool chemistry one is muriatic acid which is right here near your attic acid is simply hydrochloric acid it’s a dangerous industrial chemical you have to be trained professional to use it or you could get very hurt there’s a skin hazard you can burn yourself or there is also an inhalation hazard you can burn your lungs if you inhale it it’s very dangerous the industry has responded to that by providing what’s called a dry acid a dry acid is sodium bisulfate sodium bisulfate is another industrial chemical it’s also dangerous in the wrong hands you have to know what you’re doing to use it I’ve got a PhD in chemistry . I’m very comfortable using it you probably don’t have this if. I don’t have the experience of handling Kevin Lister most of your career so it might be a little bit intimidating for you so it really can be dangerous you have to be careful so let’s take for another example you test your pool you’ve added too much acid now your pools acidic you’ve got to bump it back up it’s kind of like we call it here go camels we call it chasing the pH the pH is too high you got to bring it down now it’s too low you got to bring it up kind of frustrating kind of annoying kind of a lot of work to do on a Saturday afternoon if your pool chemistry is too acidic you have to get more basic to do that you add another chemical yep one more chemical this is sodium bicarbonate it’s a very commonly used pool chemical this is baking soda it’s pretty harmless to you but you still have to buy it you still have to throw in your pool and this one’s sodium carbonate sodium Curtis another way to bump your pool pH back up to 7.4 it’s also relatively harmless they’re not dangerous at all but you still have to buy them and you still have to do it keep in mind the pool chemistry must be maintained very specifically in order for it to be effective this does sound like a lot of work this is a lot of work. I as a chemist would not want to do this on my Saturday afternoons when I’d rather be playing with my children so let’s think about a more convenient safer more effective way to prevent this to prevent your pool from growing bacteria or fungus and in subsequent videos. I will show you that there is a more effective method and. I hope that you’ve enjoyed this video and. I like to say again my name is Russell bass. I’m the chief scientist here at Go camelus and. I hope you’ve enjoyed this video thank you very much.
How to use Chlorine Tablets
Note: Handle Chlorine Tablets with Care
It’s always best to use precautions (use eye protection and gloves) when handling Chlorine tablets because they are highly concentrated and the chlorine can be easily absorbed into your skin.
Also, chlorine is bleach and will ruin clothes (think Clorox). If you get it on your clothing remove the clothing immediately and wash them…
And Chlorine tablets may have powder or dust that seems harmless but the chlorine powder will still cause staining and irritation so wash hands and clothes immediately.
#1. Comparing Before Buying 3 Inch Pool Chlorine Tabs
OK, let’s review three different best selling brands of chlorine tables…
And just in case you’re wondering, I used to get my chlorine tablets at Lowe’s or Leslie Pool Supplies but now I buy pool supplies and chlorine tablets online.
#2. How to add chlorine tablets to the pool (Usage):
Chlorine tablets are the most common form of chlorine and they are easier to use than the liquid. When purchasing chlorine tablets, purchase a quality brand and keep them stored in a cool and dry location away from pets and children. Fresh is best!
Remember it’s not about buying the cheapest or most affordable chlorine tablets…
Below is a chart for how many chlorine tablets to add to your pool water. This chart is for reference only but should help keep your chlorine level close to the correct levels.
#3. How Much Chlorine to Add to Your Pool?
3″ Jumbo Tabs / 8oz. PER GALLONS OF POOL WATER
Note: For reference only.
Adjust chlorine doses as needed and always read labels.
#4. How to Properly Add Chlorine Tablets to Your Pool
Congratulations! If you’re a beginner, you’ve learned how to use chlorine tablets.
Oh, BTW, you’ll need a chlorine dispenser like the one in the video but so you know they come in all sizes and designs. I’ve had to replace my dispenser around every 3 years because the sun cooks the lid and it eventually breaks. I recommend the one in the image below – it’s heavy duty.
While chlorine is an essential part of caring for your swimming pool, it’s dangerous so you need to be careful and protect yourself when handling it. Chlorine tablets make adding chlorine to your pool easy but they can be misleading.
A regular pool service schedule includes adding chlorine tablets as needed to maintain the proper level.
Caution! Most test kits advise adding ounces of liquid chlorine rather than tablets so this may take some learning to get used to their affect on your swimming pool. Careful not too much.
If you can’t figure out which is the best pool chlorine brand for you, please get professional pool service assistance.
