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.
calcium hypochlorite uses in wastewater treatment

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.

Hasa Liquidator, 8 Gallon, W/ "3/8" Upgrade

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)

PowerClean Salt Ultra 320 CMP Salt Water System Chlorinator - 20,000 Gal

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.

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.

Calcium Hypochlorite; advantages and disadvantages

Calcium hypochlorite (Ca(OCl)2) is essentially a solid that is used in place of liquid NaOCl.
As a mixture with lime and calcium chloride, Calcium Hypochlrite is marketed as chlorine powder or bleach powder for water treatment and as a bleaching agent.

Benefits of Calcium Hypochlorite

Calcium Hypochlorite structure
In addition to water treatment, Calcium hypochlorite is used in kitchens to disinfect surfaces and equipment. Other common uses include bathroom cleansers, household disinfectant sprays, algaecides, herbicides, and laundry detergents.

Calcium Hypochlorite; Advantages
This compound is relatively stable, is similar to sodium hypochlorite in disinfection properties and has greater available chlorine than sodium hypochlorite (liquid bleach).

It has excellent stability when kept in dry storage, maintaining its potency over time. Commercial grades of Ca(OCl)2 generally contain about 70% available chlorine making it appropriate for both drinking water and wastewater applications.

Calcium Hypochlorite is appropriate for both drinking water and wastewater applications.

Calcium Hypochlorite; Disadvantages
Because the chemistry is so similar to chlorine gas and NaOCl (“liquid chlorine”), this method offers no disinfection efficiency advantages (i.e., Giardia and Cryptosporidium kill rates) nor disinfection by-product advantages.

Although solid Ca(OCl)2 is more stable and safer to handle than its liquid counterpart NaOCl, it is corrosive and hygroscopic (i.e., readily absorbs moisture), reacting slowly with moisture in the air to form chlorine gas if not stored in air-tight containers.

Therefore, containers of Ca(OCl)2 must be completely sealed or emptied entirely. As with chlorine gas and NaOCl, wastewater systems using Ca(OCl)2 generally require dechlorination after disinfection to reduce chlorine discharges to receiving waters.

We at Aquatick, are Calcium Hypochlorite manufacturers, suppliers, importer & traders from India based. We have the best quality of Calcium Hypochlorite, with very competitive price. Our Calcium Hypochlorite is made with very high quality raw materials using all quality standards of the Industry.

Calcium hypochlorite is white, light dim in shading powder or granules. It is broadly utilized for water treatment and as a dying operator ,fading powder.
This concoction is viewed as moderately steady and has more prominent accessible chlorine than sodium hypochlorite, fluid fade and yearly loss of chlorine is low.

It can brighten mash, silk, fabric, fiber and starch. It is additionally utilized in managing the contaminated water, and as a compelling disinfectant general wellbeing, family sanitation, pool, drinking water, vegetables, fishpond. Furthermore, calcium hypochlorite might be utilized to make chloroform.

Regularly there are some after essential issues experienced in the support of pools.

Development of microorganisms, infections and different organisms on the surfaces of the pools and its water presented to air which may make contamination and ailments the swimmers.

Because of utilization of water by swimmers unsafe microorganisms germs get transmitted into water and become wellspring of many water borne infections.

Pollution of water from oils, fragrances, pee and so forth bestowed into the water from the body and hairs of the swimmers makes water unfit for additional use over a couple of cycles.

These are the reasons why pools require ordinary and viable treatment by disinfectants. Chlorine is a reliable and trusted sanitizer. It wrecks microorganisms and shields swimmers from illnesses.

Itis a dry type of Chlorine and is extremely protected to deal with. It is promptly dissolvable in water and is liberated from any natural substances. Because of these reasons we gives better insurance to solid, mortar, pipes and other pool gear.

It goes about as a bactericide, antiseptic and algaecide and can be utilized for purifying and cleaning purposes.
Calcium Hypochlorite for Swimming Pool Shocking

It is a solid oxidizer and can without much of a stretch obliterate natural body oils and other natural garbage if any present in the pool water.

It attempts to keep up appropriately settled alkalinity levels moving along without any more substance expansion.

Generally Suitable, Sanitizer and Versatile for Super Chlorination (Shocking) of Commercial Pool Water :

Itis generally excellent for stunning to obliterate chloramines.

Chlorine is unstabilized and henceforth there is fast development of remaining chlorine level into water, which is required for super chlorination.

Theexcess chlorine is decreased quicker to make pool accessible to swimmers in an a lot shorter timeframe contrasted with one superchlorinated with Trichloro containing Isocyanurates.

For routine cleansing additionally it is utilized in every business pool with included security by adding stabilizer independently to limit the loss of chlorine because of introduction to daylight nearly by half.

It's higher alkalinity functions as a cushion and assists with keeping the pH stable when any acidic material is brought into water. It is likewise a significant factor in keeping water from turning overcast and keep the pool water perfect and clear.

Calcium hardness protects the pool equipment and it contains calcium.

Calcium Hypochlorite: Should You Use This Type of Chlorine in Your Pool?

Whether or not you claim or keep up a pool, chlorine has for quite some time been a natural synthetic in the pool business.

In addition to the fact that chlorine is an exceptionally powerful pool sanitizer, but at the same time it's the most cheap sterilizing operator available. Indeed, it's therefore that a large portion of the world's pools depend on chlorine in any case.

Obviously, not all chlorine is made equivalent, and understanding what isolates the different sorts of chlorine items is fundamental for appropriate pool water treatment. Today, we'll be investigating one sort specifically; calcium hypochlorite.

What is Calcium Hypochlorite?

Calcium hypochlorite—or what the vast majority simply call "cal hypo"— is one of different sorts of chlorine you can purchase, and it looks precisely how you'd expect pool chlorine to look.

It's generally normally sold as a white, chlorine-smelling powder/granules, which are then emptied straightforwardly into the pool water, or once in a while by means of the pool skimmer. It has an exceptionally basic pH level at around 11-12, and contains somewhere in the range of 65-75% free accessible chlorine.

These are ordinarily sold in 1lb sacks, yet it merits considering a mass purchase in case you're intending to utilize cal hypo routinely.

It's likewise less normally found in tablet structure. It would seem that a white hockey puck in either 1″ or 3″ sizes, which is then broken down and dribble took care of in a specific feeder. It has a marginally lower pH level of around 9.

Despite physical structure, neither the powder or tablet forms of calcium hypochlorite contain pool stabilizer (cyanuric corrosive) to secure against the sun, however rather contain calcium which raises your pools calcium hardness level after some time.

Cal-Hypo Quick Stats

Powder structure has a pH level around 11-12

Tablet structure has a pH level of around 9

Contains around 65-75% chlorine

Doesn't contain pool stabilizer

Contains calcium that will raise calcium hardness

How Does Calcium Hypochlorite Work?

All things considered, it works simply like some other sort of chlorine.

In the wake of adding calcium hypochlorite to your pool, the chlorine rapidly responds with the water to shape Hydrochloric Acid. It's this corrosive that assaults and slaughters the infinitesimal trouble makers drifting around.

It does this "murdering" by consolidating with any danger it experiences, separating the phone divider and successfully rendering it pointless. The subsequent consolidated chlorine is additionally alluded to as chloramines.

Presently, in light of the fact that it works in a general sense equivalent to some other sort of chlorine once it's in the water, each have one of a kind characteristics that you have to comprehend so as to pick the correct chlorine item for your particular use-case.

How about we tackle that next.

The Pros and Cons of Calcium Hypochlorite

Considering utilizing cal-hypo in your pool?

So far I've quite recently tossed a lot of portrayals and realities at you, however I've yet to discuss what these mean from a down to earth viewpoint, and all the more significantly, if calcium hypochlorite is even a savvy alternative for sterilizing a pool.

Benefits of Calcium Hypochlorite

It's exceptionally solid, so you'll have to utilize less item to arrive at the necessary degree of free chlorine in your pool.

It's quick acting since it's a huge, pre-broken down sum being added to the water.

It won't harm your pool or the gear if appropriately pre-broken down and poured.

It's anything but difficult to move, so getting locally is moderately effortless, and dispatching costs are sensible as well. It comes in little 1lb sacks with a timeframe of realistic usability of up to 2-3 years.

It's entirely moderate. As far as dynamic chlorine content, it's probably the least expensive sort of chlorine you can purchase after sodium hypochlorite (fluid chlorine).

Other Potential Benefits/Drawbacks

The accompanying focuses can either be advantages of disadvantages relying upon the momentum condition of your pool water science:

It's unstabilized, which means it doesn't contain any cyanuric corrosive, so it has almost no security from the sun and will consume off rapidly if your pool is presented to daylight. This is just valuable on the off chance that you need a brief chlorine help (more in that momentarily), however you could likewise include cyanuric corrosive physically.

It has a high pH, so it will probably raise your pools pH level. This can be valuable on the off chance that you coincidently need to raise your pH, however badly designed on the off chance that you don't. You can utilize muriatic corrosive to bring the pH level down, be that as it may.

It adds calcium to your pool water. Once more, this is helpful on the off chance that you have to raise your calcium hardness levels, however an excessive amount of prompts calcium scaling which isn't something that can undoubtedly be fixed.

Calcium Hypochlorite for Swimming Pool Shocking

At the point when consolidated chlorine (chloramine) develops a lot in your pool, it can begin to keep free chlorine from viably carrying out its responsibility, just as causing skin and eye bothering.

To expel the chloramines from your pool water, you'll have to "stun" your pool. This procedure includes including 10x the measure of chlorine to your pool as there is chloramine, which separates the chloramine particles, making them off-gas (oxidize).

It's a smart thought to do this once every week to forestall a solid development of chloramines, however stunning can likewise be utilized to battle a green growth sprout or different contaminants entering the water, for example, human waste. That's right, it occurs.

In principle, you can stun your pool with a chlorine as long as you include enough of it, however calcium hypochlorite is especially fit in light of the fact that, as referenced previously:

It's solid, which implies you need less item to arrive at 10x the degree of consolidated chlorine (or what's known as "breakpoint chlorination")

It's quick acting since it's as of now broke up when it enters the water. It takes about around 8 hours to do its thing, and you'll leave it to work for the time being on the grounds that…

It's unstabilized, which implies the sun will consume it off speedier. On account of stunning, you really need this to happen on the grounds that you just need short explosion of chlorine before bringing the chlorine level down to ordinary.

Furthermore, on the grounds that stun requires a less regular application, the additional calcium and slight increment in pH is a lot simpler to oversee, particularly when the remainder of your water science is appropriately adjusted.

Getting to grasps with the various kinds of chlorine can be trying for new pool proprietors, however ideally you would now be able to tick calcium hypochlorite off your rundown.

While trichlor tablets and fluid chlorine are better alternatives for normal chlorination, cal hypo takes the crown with regards to stunning your pool—regardless of whether it's a standard week by week stun or a crisis treatment.

Good karma and upbeat swimming!
