Cal hypo does not contain stabilizer (cyanuric acid), though it can be stabilized toward sunlight in recreational water through the use of cyanuric acid. You can buy it in slow dissolving tablet forms, or more rapidly dissolving granular forms, depending on your needs.

What type of chlorine is stabilized?

Cyanuric acid stabilizes chlorine, making it last longer in the pool. Without it, chlorine is quickly burned off by the sun's ultraviolet (UV) rays. Unstabilized chlorine is simply chlorine that has not had cyanuric acid added to it.

Does sodium hypochlorite have stabilizer?

While calcium hypochlorite and liquid sodium hypochlorite were enjoying mainstream popularity in backyard pools, the fact remained that both forms of hypochlorite do not contain a stabilizer like CYA.

Why is calcium hypochlorite stable?

This compound is relatively stable and has greater available chlorine than sodium hypochlorite. It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air....Calcium hypochlorite.NamesOther anionsCalcium chlorideOther cationsSodium hypochlorite40 more rows

What are disadvantages of using calcium hypochlorite to keep a home swimming pool clean?

The Drawbacks of Cal-Hypo It causes temporary cloudiness if using large amounts of powder, but the cloudy water should clear up by itself unless other factors are at play. It requires a special feeder when using cal hypo tablets because they need partial exposure to water to prevent them from dissolving too fast.

What's the difference between sodium hypochlorite and calcium hypochlorite?

Sodium hypochlorite solutions are clear, greenish to yellow liquids with an odor of chlorine. Calcium hypochlorite is a white solid that readily decomposes in water releasing oxygen and chlorine. It also has a strong chlorine odor. Neither compound occur naturally in the environment.

Why should calcium hypochlorite and sodium hypochlorite never be used together?

Calcium hypochlorite decomposes in water to release chlorine and sodium hypochlorite solutions and can release chlorine gas if mixed with other cleaning agents.

How long does calcium hypochlorite last in water?

Calcium Hypochlorite is only a few bucks and you can find it at swimming pool supply stores such as Deep Blue Pools and Spas . This is also referred to as pool shock. Keep in mind that when the granular calcium hypochlorite is made into the liquid chlorine solution it does have a shelf life of about 24 months.

What happens when calcium hypochlorite is mixed with water?

Calcium hypochlorite has the molecular formula of Ca(ClO)2 and a molecular weight of 142.974 g/mol. Its CAS number is 7778-54-3. Its specific gravity is 1.21 g/cm3. When dissolved in water, it can provide nascent chlorine and oxygen to sterilize pool water or industrial wastewater.

Why is calcium hypochlorite more stable than sodium hypochlorite?

Sodium hypochlorite is a very unstable compound. Calcium hypochlorite has a melting and boiling point of 100°C and 175°C, whereas the melting and boiling points for sodium hypochlorite are 18°C and 101°C. Calcium hypochlorite has a higher amount of chlorine in its composition compared to sodium hypochlorite.

How long after adding calcium hypochlorite can you swim?

You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.

How long does it take calcium hypochlorite to dissolve?

This means that 68% of each pound of pool shock is calcium hypochlorite ions, the remaining inert ingredients are binders and salts produced during the reaction with lime used in manufacture. These binders will release and dissolve within 15 seconds, in 70° pool water that is circulating.

Does calcium hypochlorite raise chlorine levels?

You want to raise the chlorine level to 10 ppm. The product label states that 20 ounces of calcium hypochlorite will raise the chlorine level by 10 ppm in 10,000 gallons of water.

How do you stabilize bleach?

Sodium metabisulfite is an effective bleach neutralizer. 2.2 grams (one teaspoon) of sodium metabisulfite added to 2.5 gallons of water effectively neutralizes all harmful bleach residue.

What is in sodium hypochlorite?

Sodium hypochlorite (NaOCl) is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells. Sodium hypochlorite, commonly referred to as bleach, has a variety of uses and is an excellent disinfectant/antimicrobial agent.

Is sodium hypochlorite an oxidizer?

Sodium Hypochlorite is not combustible but is a STRONG OXIDIZER which enhances the combustion of other substances.
