Bleach VS Chlorine For Pool: What’s the Difference?

The thing is they are not the same at all. Bleach contains chlorine, as it is the basis for bleach, but they are not the same. According to Wikipedia, bleach is most commonly in the form of sodium hypochlorite, NaClO, and also calcium hypochlorite, Ca(ClO)2, which is bleach powder.

There are also bleaches that do not even use chlorine, like hydrogen peroxide.

Easiest Way to Keep Your Swimming Pool Clean

KEEPING YOUR POOL CLEAN

Swimming pool water contains viruses, bacteria, algae, germs and a variety of other nasty things. That's why keeping swimming pool clean is important to protect you and your pool from these contaminants. Without a doubt, using is the absolute best sanitizer for your swimming pool. There are plenty of other ways to sanitize your pool, but they all fail in effectiveness and ease of use compared to chlorine.

Got your attention? Good. Then let’s get some chlorine in your pool!

Chlorine, in a swimming pool, is a consumable, and needs to be constantly replenished and reintroduced to your pool. A typical swimming pool requires about 2-3 ppm of chlorine daily to keep the pool safe and properly sanitized. Because there are several ways to handle this necessity, we offer the following options:

1. Liquid chlorine

Household bleach (the same as you use for your laundry) and pool chlorine are the same thing. They are identical in every way, with the exception of strength. Household bleach is usually a 6% concentration (although some of the cheaper stuff is 3%), while pool chlorine can typically be found in strength between 10% and 12%. All of this is sodium hypochlorite, and works the same in sanitizing your water. If you choose to buy bleach (chlorine) at the grocery store, make sure you buy the unscented variety. Obviously, the “weaker” formula will require more than the higher concentration type.

The biggest advantage of liquid chlorine is that it adds nothing to your pool except water, chlorine, and a small amount of salt. With the exception of having to handle bulky jugs, liquid chlorine is the easiest method of introducing this sanitizer to your pool, while adding the least amount of unwanted “fillers’ or other chemicals to your pool. Besides manually pouring chlorine in to your pool, the addition of a Liquidator (or LQ, manufactured by HASA) or a peristaltic pump to introduce chlorine to your pool provides ease and a daily dosing of chlorine, helping to maintain a more balanced, and consistent, chlorine residual.

2. Calcium Hypo

Usually powdered form of chlorine. It is very easy to carry. Convenience, like that of tri-chlor, is what sucks you in. In the long term, like most things that sound too good to be true, that convenience comes with a price. Nearly one third of cal-hypo is calcium, and that goes into your pool water and you can’t get it out; not a good thing, especially for those of us in hard water areas. Consistent use of cal-hypo can result in elevated calcium levels. By allowing calcium to get too high in your pool, you are inviting scale, build up on your waterline tile and spillways/water features, as well as inside your heat exchanger of your heater and the grid plates of your SWCG. Too much calcium causes many problems, and requires considerable work (and sometimes expense) to remedy.

3. Tri-chlor

This is most commonly sold as tablets or pucks that you place in a “floater” in your pool or a tablet feeder plumbed in line at your equipment, and they add chlorine and CYA into your water, while also lowering the pH. They are extremely convenient, and can cause more trouble than you may imagine. The CYA that they add to your pool water every day does not get used up, and builds to greater and greater levels. Eventually, the CYA level will get to the point in which it renders your chlorine completely ineffective. While a little CYA is a good thing, too much serves to block the chlorine completely, and once you wake up to a green pool and see what it takes to kill that algae in a pool with these high levels you will understand why this convenience really isn’t worth it! These “pucks” also carry a pH of around 2.5, very acidic and detrimental to pool plaster.

Floating Pool Chlorine Tablet Displenser

There are many different types of floaters and tablet dispensers available in the market. Just choose what suits your style and needs.

4. Dichlor

Stabilized form of chlorine. It is granular and fast-dissolving. Sold often as “shock” at the various pool stores. In similar fashion to tri-chlor, di-chlor adds chlorine and CYA to your water and lowers the pH. Be warned though, continuous use of dichlor can raise your CYA level very quickly, that can lead to the same problems as mentioned above.

5. Salt Water Chlorine Generators (SWCG)

Installed in your pool plumbing system (always plumb a salt cell after your spa bypass, if you have a pool/spa combo) and electrically powered at the same time as your circulation pump is running, SWCG produce chlorine from salt that has been added to your pool. SWCG are covered in greater depth in the Salt Water Chlorine Generators section under “Building and Equipment”, and ease of use is by far their single best feature, whereas the large initial investment to purchase the system is their biggest drawback. You must understand that it is critical to maintain balanced water for a SWCG to properly work, and you will be disappointed if you expect it to do everything for you! It requires attention, just like most components of your pool.

In summary, liquid chlorine (bleach) or a SWCG are your two best options. Both will maintain your swimming pool and provide safe water all summer with little, if any, side effects.

CALCIUM HYPOCHLORITE: SHOULD YOU USE THIS TYPE OF CHLORINE IN YOUR POOL?

WHAT IS CALCIUM HYPOCHLORITE?

Calcium hypochlorite—or what most people just call “cal hypo”—is one of various types of chlorine you can buy, and it looks exactly how you’d expect pool chlorine to look.

It’s mostly commonly sold as a white, chlorine-smelling powder/granules, which are then poured directly into the pool water, or sometimes via the pool skimmer. It has a highly alkaline pH level at around 11-12, and contains anywhere from 65-75% free available chlorine.

These are typically sold in 1lb bags, but it’s worth considering a bulk-buy if you’re planning to use cal hypo regularly.

It’s also less commonly found in tablet form. It looks like a white hockey puck in either 1″ or 3″ sizes, which is then dissolved and drip-fed in a specialized feeder. It has a slightly lower pH level of around 9.

Regardless of physical form, neither the powder or tablet versions of calcium hypochlorite contain pool stabilizer (cyanuric acid) to protect against the sun, but instead contain calcium which raises your pools calcium hardness level over time.

HOW DOES CALCIUM HYPOCHLORITE WORK?

Well, it works just like any other type of chlorine.

After adding calcium hypochlorite to your pool, the chlorine quickly reacts with the water to form Hydrochloric Acid. It’s this acid that attacks and kills the microscopic bad guys floating around.

It does this “killing” by combining with any threat it encounters, breaking down the cell wall and effectively rendering it useless. The resulting combined chlorine is also referred to as chloramines.

Now, just because it works fundamentally the same as any other type of chlorine once it’s in the water, each have unique qualities that you need to understand in order to choose the right chlorine product for your specific use-case.

The Benefits Of Cal-Hypo

It’s very strong, so you’ll need to use less product to reach the required level of free chlorine chlorine in your pool.

It’s fast acting since it’s a large, pre-dissolved amount being added to the water.

It won’t damage your pool or the equipment if properly pre-dissolved and poured.

It’s easy to transport, so picking up locally is relatively painless, and shipping costs are reasonable too. It comes in small 1lb bags with a shelf-life of up to 2-3 years.

It’s very affordable. In terms of active chlorine content, it’s one of the cheapest types of chlorine you can buy after sodium hypochlorite (liquid chlorine).

CALCIUM HYPOCHLORITE FOR POOL SHOCKING

When combined chlorine (chloramine) builds up too much in your pool, it can start to prevent free chlorine from effectively doing its job, as well as causing skin and eye irritation.

To remove the chloramines from your pool water, you’ll need to “shock” your pool. This process involves adding 10x the amount of chlorine to your pool as there is chloramine, which breaks up the chloramine molecules, causing them to off-gas (oxidize).

It’s a good idea to do this once per week to prevent a strong buildup of chloramines, but shocking can also be used to fight an algae bloom or other contaminants entering the water, such as human waste. Yep, it happens.

In theory, you can shock your pool with any type of chlorine as long as you add enough of it, but calcium hypochlorite is particularly suited because, as mentioned above:

It’s strong, which means you need less product to reach 10x the level of combined chlorine (or what’s known as “breakpoint chlorination”)

It’s fast-acting because it’s already dissolved when it enters the water. It takes about around 8 hours to do its thing, and you’ll leave it to work overnight because…

It’s unstabilized, which means the sun will burn it off quicker. In the case of shocking, you actually want this to happen because you only need short burst of chlorine before bringing the chlorine level back down to normal.

And because shock requires a less frequent application, the added calcium and slight increase in pH is much easier to manage, especially when the rest of your water chemistry is properly balanced.
