Whats better liquid shock or granular?

The most common form of granular shock is called Calcium Hypochlorite

Calcium Hypochlorite

Calcium hypochlorite is an inorganic compound with formula Ca(OCl)₂. It is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for water treatment and as a bleaching agent.

, known as Cal Hypo. This type of shock is much stronger than liquid shock typically has 65 to 75 percent available chlorine.

Does liquid shock work better than powder?

Both liquid and powder shocks contain the same active chemical used for pool sanitation, but their usage and strength are different. Other than coming in a different form, liquid chlorine is also more budget-friendly and unstabilized. On the other hand, powder shock is easy to stabilize, and its solid form dissolves.

Is liquid or granular chlorine better?

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.

Is liquid shock the same as granular shock?

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.

Is liquid chlorine better than shock?

Liquid chlorine is generally less costly than granular shock and comes in refillable containers, where granular shock does not. Liquid chlorine does not need to dissolve in your water as it is already in liquid form. In addition, liquid chlorine is non-scaling and leaves no residue.

Liquid Chlorine or Granular Chlorine Compared - Shock Your Pool

How quickly does liquid shock work?

Always run the pump when shocking the pool and allow it to circulate for 24 hours. The water should then be a blue or cloudy blue color. Test the water 24 hours after shocking and start adjusting pH and alkalinity levels.

Does liquid chlorine raise pH?

Using liquid chlorine raises the pH of the water.

Liquid chlorine does not raise pH. 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.

What happens if you swim in a shocked pool?

What Happens If You Swim In A Shocked Pool? If you do not wait for the chemicals used to shock a pool to totally dissolve then you could be placing yourself in serious danger by swimming in it. At the minimum, you will feel itchy skin and eyes because of the chemicals present in the water.

How long should you wait to swim after shocking pool?

After you shock the pool — As soon as your chlorine levels reach 5 ppm or lower, it's officially safe to swim. Depending on the type of shock used, as well as the amount used, it can take anywhere from 24 hours or even up to a couple of days.

Can you use shock and chlorine together?

Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock. Without tabs, the chlorine shock will dissipate quickly out of the water; without shock, the chlorine level will not get high enough to fully sanitize the water.

What is the difference between chlorine granules and shock?

Shocking will restore the proper chlorine level and restore water clarity. Both available in various forms: Chlorine comes in liquid, dissolvable granules, and granule pucks/tablets for slow-release. While shock is more fast-acting, it's also available in both granule (most common) and liquid forms.

How often should you shock your pool?

How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.

Is liquid chlorine best for pool?

Liquid chlorine can be great for pools BECAUSE it has no stabilizer and it doesn't leave any residues or other chemicals behind. Without added stabilizer (CYA), liquid chlorine simply raises chlorine levels without increased CYA levels. That's a big advantage if you have high levels of CYA in your water already.

How long after shock can I add chlorine?

You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.

How much shock do I need for a 15000 gallon pool?

Typically for granular shock, you'll need one pound for every 10,000 to 13,500 gallons of pool water.

Can I swim 12 hours after shocking pool?

After Shocking Your Pool

It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first!

Why did my pool get cloudy after I shocked it?

High doses of chlorine, like pool shock, can cause temporary cloudiness as it kills contaminants. High levels of pH, alkalinity, and calcium hardness are more likely to cause cloudy water.

How long should you run filter after shocking pool?

While shocking your pool will help kill any germs any algae, it won't actually get rid of them; for that, you need your filter. So be sure to run your pool filter for at least 24 hours.

Does Shocking a pool lower alkalinity?

Another cause for high alkalinity can be when you shock the pool. While this is performed to quickly rid the pool of pollutants, chlorine-based pool shock is highly alkaline, and can raise the water's total alkalinity level in the process.

Can I shock pool with high pH?

The most optimal and effective pH level to shock a pool is anywhere between 7.2 and 7.4. If the pool water is anywhere outside of this range, the water will not be suitable for the shock, making the treatment significantly less effective.

Does Rain lower pH in pool?

Rainfall dilutes pool chemistry levels and lowers the readings for pH, alkalinity, hardness, stabilizer, and chlorine. Rainfall does not contain chlorine.

Will liquid chlorine clear a green pool?

Will chlorine clear up a green pool? Yes! In fact, enough chlorine kills algae which causes green pool water. but it takes a large amount in the form of calcium hypochlorite super shock.

How do you use liquid shock in a pool?

What should pH be before shocking pool?

Before you add shock treatment, you need to test your pool water and balance its levels. The pH level should be between 7.2 and 7.6, with total alkalinity being between 80 and 120 ppm.
