How does chlorine work?
First of all, you have to know the importance of using chlorine.
There are other sanitizers that get the job done, but none do it as well as good ol’ inexpensive chlorine.
Chlorine works because of a chemical reaction that takes place once it comes in contact with microorganisms and bacteria.
It breaks down into several different chemicals like hypochlorous acid (HOCI) that kills those unwanted pests by destructuring the cells that create them.
The process is called oxidation, which is why some pool owners add more oxidizer to the water when using chemicals that don’t do the job well.
Chlorine only does its job, however, if all the other pool chemistry levels are balanced.
or example, if the pH level is too high, it will block some of the HOCI, leaving the pool less than optimally oxidized.
So, for chlorine to do its job well, all levels including pH, alkalinity, cyanuric acid, calcium hardness and chlorine need to be within normal ranges, which are:
Types of chlorine
First of all, let’s explore some of the science-y basics of chlorine.
The different types of chlorine are: lithium hypochlorite, trichlor, dichlor, sodium hypochlorite, and calcium hypochlorite.
And each of them serves its own purpose, although most people just pick up whatever is available at the local pool store and call it good.
Most of the time, that’s probably okay, but in some instances, one is better than another.
For example, if you happen to have hard water where you live (or water with high calcium hardness), sodium hypochlorite works best because it contains only about 10-12% chlorine.
This usually has to be used with additional sanitizer, however, to be effective at killing algae or other bacteria.
Calcium hypochlorite, or cal-hypo, is the most commonly used chlorine for pools because it is safe and easy to use. It is also very effective, containing about 65% chlorine.
That is except for trichlor and dichlor, which are are concentrations of chlorine that contain cyanuric acid (CYA).
CYA is what’s known as a conditioner or pool stabilizer because it protects the chlorine molecules from being destroyed too quickly by the sun.
Most chlorine tablets you can buy are trichlor tablets, which are effective for most all water types.
Why tablets?
But why tablets?
Most of the time, pool-owners who use tablets instead of liquid or granular chlorine are simply doing it for the convenience.
Instead of having to measure anything out, you just need to know your pool size and drop the tablets in.
One 3-inch tablet will sanitize about 5,000 gallons of water. So if you have a 20,000 gallon pool, two tablets will do the trick.
There is also the factor of safer handling.
Liquid chlorine can be somewhat dangerous to handle if you’re not careful, causing skin burns or irritation.
But tablets are pretty safe to handle and in fact, are usually individually wrapped so they don’t have to touch your skin.
They also don’t pose the same spill risk as liquid, making them easier and safer to store.
Shopping tips
If you decide to go with chlorine tablets as your choice of sanitizing methods, be sure to read the reviews of the product you choose.
While there may not be a whole lot of difference in the chemicals they contain, some are just made with better methods and won’t crumble during shipping.
They come in one or three inch tablets and it doesn’t matter which size you choose as long as you read the instructions and administer the right amounts.
Some people prefer the larger tablets because they’re a little easier to handle, especially if you will be adding them directly to the skimmer.
But some prefer the smaller ones for automatic dispensers because you can fit more in them.
