Non-chlorine shock, such as Leslie’s Fresh ‘n Clear, is an oxidizer. It uses the power of “active oxygen” to destroy contaminants in pool and spa water. This eases the load of your regular FAC residual, allowing that chlorine to stay effective longer. This, in turn, prevents chloramines from building up.
Does oxidizing shock raise chlorine?
Adding shock to your pool will oxidize and destroy organic material, giving a boost to your free chlorine. It will also oxidize the combined chlorine and allow it to gas off, reducing the total chlorine in your pool and making it more pleasant to swim in.
Does oxidizing shock raise pH?
Both an oxidizer and sanitizer, cal hypo is quick dissolving and is the most frequently used in the pool industry. It will slightly raise your pH, so make sure you adjust pH while using it. As the name implies, it will also raise your calcium hardness levels in your pool slightly.
Is shock oxidizer the same as chlorine?
The shocking agent, typically a non-chlorine oxidizer, breaks down the chloramines so that they can help in the sanitizing process. Basically, it becomes chlorine again. There are two types of shocking agents — chlorine and non-chlorine. Most non-chlorine shocks are labeled as oxidizer, a nod to the chemical reaction.
When should I oxidize my pool?
The Proper Chlorine Level If you’ve chlorinated your pool several times and the water still looks green or murky, it’s a sign that you should use an oxidizing shock product.
What is the difference between shock and shock oxidizer?
Oxidizers break down organic matter, ensuring clean water. You should shock your hot tub once a week. Shocking removes organic compounds that are added to the water by anyone who bathes in it. Sanitizers and oxidizers are two different chemicals, used for two different purposes.
Will shock raise free chlorine?
The term, “Shocking” refers to the process of adding chlorine or non-chlorine chemicals to your pool in order to raise the “free chlorine” level to a point where contaminates such as algae, combined chlorine (also known as chloramines) and bacteria are destroyed.
How do you use oxidizing shock?
What pool shock does not raise cyanuric acid?
Potassium Monopersulfate (Non-Chlorine Shock) Unlike both cal-hypo and dichlor, MPS won’t change your pool’s cyanuric acid levels. Known as the “shock and swim” method, MPS can be used at any time of the day. You can start swimming nearly 15 minutes after using this shock.
Does non-chlorine shock raise or lower pH?
No, non-chlorine shock will not raise chlorine levels. It can, however, affect the pH balance. The average pH of non-chlorine shock is 2.3, which can bring your pH out of its normal range (7.4 to 7.6).
Why does pH in pool keep dropping?
The most common cause of a consistently low pH level in pools is using chlorine tablets or stabilized forms of chlorine. These have a pH level of around 3. Acidic rainfall, heavy leaf debris, and dirt/mulch in the pool can also lower the pH level.
Does non-chlorine shock lower alkalinity?
Finally, using a non-chlorine shock treatment will lower the pool’s total alkalinity, and at the same time, raise the TDS (total dissolved solids) level in the water.
Can I add chlorine and oxidizer at the same time?
It Should Not Be Done Together This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM. Only then should you introduce algaecide to get the best results.
Do I need chlorine if I use shock?
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.
Can I just use shock instead of chlorine?
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. Short answer: No.
How long does it take for oxidizing shock to work?
Oxygen based non-chlorine shock that effectively removes contaminants (swimmers’ waste) and restores sparkle to pool water. Swim within 15 minutes after treatment. Ideal for all pool surfaces.
How long does it take for a pool oxidizer to work?
You can choose between a chlorine-based oxidizer or a nonchlorine oxidizer, and once it is applied, it’s necessary to wait a minimum of 12 hours before jumping back into the pool. Adding these chemicals at night is recommended to minimize the UV rays affecting or altering the chemical compounds.
What does it mean to oxidize pool water?
So, what is oxidation in pool or spa water? Oxidisation is the chemical reaction that occurs when a reactive substance (chlorine or oxidisers) interacts with unwanted organic matter (sweat, leaves, suntan lotion, algae, etc). The chlorine you add to your pool is there to attack and destroy unwanted bacteria.
Can you put too much shock in a pool?
A common question among pool owners is, “Can I over shock the pool?” The short answer is no. You can add more shock than needed, which is a waste of money and materials. You can also get green hair from a reaction to high levels of chlorine. In general, however, over-shocking is harmless.
Does shock lower chlorine levels?
Shocking the pool means adding extra chlorine to the water to eliminate excess bacteria, algae and other microorganisms from your pool. If you miscalculate and add more tablets or granules than necessary during the shocking process, or during routine maintenance, this can cause a high chlorine level.
Will non chlorine shock clear cloudy water?
If you have milky or cloudy hot tub water but your chlorine levels, PH and alkalinity are ok then Non Chlorine Shock will oxidise the products causing this and help restore your water to crystal clear.
Why is my free chlorine always low?
Things that cause low free chlorine levels are excessive sunlight, high bather loads, and improper water chemistry. An increased organic activity in your swimming pool will also cause the little bit of chlorine that’s in there to be used up faster too.
How long should I run my pool pump after shocking?
It is a question a lot of pool owners have and a question that we have the answer to! A pool filter should be run for a minimum of 6 hours after shocking a swimming pool. This is to allow the filter to clean the water and give the shock enough time to fully mix with the pool water.
Does shock raise alkalinity?
Causes of Rising Alkalinity It’s also not uncommon for pool owners to go a bit overboard when shocking their pool, and since chlorine-based pool shock is a high-alkaline substance, it will also naturally raise your pool alkalinity.
