Liquid chlorine may be a good choice if you have a large pool, but the costs associated with it, and the available chlorine per pound could mean that chlorine granules are the better option. In the end, both liquid chlorine and chlorine granules will do their job and keep your pool clean and clear.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
Sodium Dichloroisocyanurate [Dichloro-S-Triazinetrione] (Dichlor) Dichlor is perhaps the most “best of all worlds” chlorine sanitizer. It is typically found in concentrations of 60-65%, which is comparable to cal-hypo.
We dive in and find out. Liquid chlorine is preferred over chlorine tablets by pool professionals however home swimming pools will benefit too. Liquid chlorine quickly raises or maintains chlorine levels without raising stabilizer. Chlorine tablets maintain chlorine levels and add stabilizer to the pool water.
Liquid chlorine leaves no residue and can be up to 80% less expensive. Also, it's the most commonly used pool sanitation method. It's available in refillable containers, and it doesn't need dissolving as it's a liquid. On the other hand, powder shock is easier to carry and lasts longer.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
Unlike liquid chlorine solutions that are nothing more than chlorine mixed into water, chlorine tablets are typically composed of chlorine and a stabilizing component which is usually cyanuric acid or CYA.
All pool chemicals, aside from unstabilised liquid chlorine, are good for up to three to five years as long as they're stored in a cool and dark place away from sunlight and they're packed in air-tight containers.
Daily-Use Chlorine Products. When it comes to pool chemicals and cleanliness, Chlorine is by far the most popular choice for above ground pools with decks, on ground pools, semi inground pools, or even wells.
The way you apply granular chlorine to the pool is by using a large pail and fill it with hot water (the exact quantity of water doesn't matter, just fill the pail). You then add the granular chlorine to the water in the pail (always chlorine in water, never water on chlorine).
Lithium hypochlorite has a higher range of 28 to 35 percent chlorine. This allows it to more effectively maintain the chemical balance of the pool water, but lithium hypochlorite is also non-stabilized and vulnerable to UV radiation.
Chlorine granules, meanwhile, are simply scattered over a pool. Their combination of a smaller consistency and lower concentration makes them much more suitable for this purpose than chlorine tablets, as they dissolve more easily. This, in turn, enables them to fight pool bacteria much more quickly as well.
Chlorine granules, especially dichlor, have a lower pH than liquid chlorine, so you can mix them into your pool water without having to add acid.
Typically, a 3-inch pool chlorine tablet is designed to chlorinate from 7,500 to 10,000 gallons of water per week, meaning it'll take seven days to dissolve. If you have a 30,000-gallon pool, you'll need to place three 3-inch pool chlorine tablets in a chlorinator or floater.
Are chlorine and shock the same thing? SKIMMER NOTES: No. Chlorine and shock are not the same thing. Shock has a more intense chemical strength than the traditional chlorine sanitizers, and it also differs in how you should apply it to your swimming pool.
Pour the liquid chlorine into the pool with the jug as close to the water surface as possible in order to prevent splashing. Add the liquid chlorine to the deep end of the pool. After all of the liquid chlorine has been added, brush the walls and floor of the pool.
If the water is very low on chlorine, place a chlorine dispenser that floats around in the pool with granular chlorine in it. The granular chlorine will dissolve fast and bring the level up to where it should be.
Shock-chlorination is an essential and effective method of cleaning the pool. But you need to have the pump circulating the water for this to be effective.
Granular chlorine when kept in airtight containers that are cool and dry can last for over five years, though when stored otherwise and exposed to humidity it can dissolve in under two years.
Using liquid chlorine raises the pH of the water.
When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.
Liquid Chlorine
The liquid form of chlorine is the cheapest way of adding chlorine to a pool. Simply pour it directly into the water in front of a return jet to disperse it throughout the pool.
Chlorinating Liquid is a popular choice among pool owners and can be used as a substitute when chlorinating tablets may be unavailable. Chlorinating liquid is not stabilized, which means it may require a chlorine stabilizer to help the chlorine last longer.
Depending on how much you have added and the size of your pool, it is generally safe to wait about 4 hours after adding liquid chlorine or until levels reach 5 ppm or lower.
Granular Shock: Granular or powdered oxidizers 4 types and 6 strengths. The most common form of granular shock is called Calcium Hypochlorite, known as Cal Hypo. This type of shock is much stronger than liquid shock typically has 65 to 75 percent available chlorine.
