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.
Non Chlorine Shock is a powerful, odourless oxidising agent, which essentially means it works to eliminate contaminents in hot tub water. Oxidation is different to sanitisation. Oxidation is the breaking down of the oils and organics in your water whereas sanitisation is the killing of bacteria.
Conclusion. Non-chlorine shock is a good option if you want to get rid of organic debris and murky water and go right back to swimming. It is also effective to reduce combined chlorine. If you have an algae bloom or are worried about extra bacteria from a heavy load of swimmers, only chlorinated shock will do the trick ...
Non-chlorine pool shock is also very stable in high water temperatures. This makes it ideal for use in spas or hot tubs, where the spa water temperature can reach up to 102°F.
After NON-CHLORINE shock wait 10-15 minutes before entering. After chlorine shock it can take up to 24 hours to clear. Therefore it is recommended to use non-chlorine shock. It is always recommended to test with a PH strip again before entering.
Non-chlorine shock makes waiting around for hours after shocking your pool a thing of the past. That said, it should be noted that non-chlorine shocks don't kill algae, or raise the chlorine level.
You will find that after oxidation of your bromides using a non-chlorine spa shock your bromine level will spike, and that's because you are really shocking with bromine!
Total alkalinity determines how well water can neutralize acids. When applied in significant quantities, non-chlorine shock can cause your pool water to have unhealthy total alkalinity levels.
A non-chlorine oxidizer removes contaminants from your water. These can include body oils, lotions, ammonia, and sweat. One of the benefits of using a non-chlorine oxidizer is that it allows your chlorine to do its best work in the hot tub water.
Adding chlorine besides the shock can increase the chlorine content in the water which can make the entire shocking process useless. Hence, it is better if you don't use the shock and chlorine at the same time. The best time to add chlorine to the pool water is after you have shocked the pool.
Non-Chlorine shock will destroy your basic bacteria, but for the stronger varieties, it just can't get past their defensive walls. For control of pathogenic bacteria, those that can make you sick, a shock treatment with chlorine will neutralize 100% of germs, to sanitize and disinfect the water.
When you're shocking a pool, the goal is to raise the free chlorine level of the pool water to roughly 10 times the combined chlorine level.
Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Non-chlorine shock doesn't contain chlorine itself, and does not disinfect the water. Non-chlorine shock helps the chlorine already in your hot tub work better by oxidising the water and creating “free chlorine” – which is what is needed to kill bacteria.
Broadcast the required amount of Leslie's Fresh 'N Clear uniformly over the surface of the water, adding two-thirds of the total dose over the deep end of the pool. Apply with the circulation pump running to ensure complete distribution and good circulation.
Basically, it uses reactive oxygen (“active oxygen”) to oxidize and remove contaminants from pool and spa water such as those found in sweat, urine and windblown debris. So it doesn't add chlorine to your pool, and it doesn't create chlorinated by-products — like chloramines.
Bromine: Is gentler on your skin than chlorine, but can be a bit more difficult to wash off after a long soak. If you or anyone who uses your hot tub on a regular basis has sensitive skin or any kind of upper respiratory difficulties, bromine will likely be the better choice.
Non-chlorine shock is monopersulfate compound, often called MPS for short. It is an oxygen-based shock, preferred by many because it has little or no odor. Our OxySpa non-chlorine shock is 100% compatible with chlorine, bromine, Cleanwater Blue, Nature2, Frog products, and dichlor shock.
Bromine. Use chlorine shock. But, just as with chlorine, you can also use non-chlorine shock for all the same reasons. Again, we recommend sticking with chlorine shock if you have a high bather load.
High pH level
When you shock a pool, you test and adjust the pH level for a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.
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.
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.
The Advantage of Chlorine Tablets for Swimming Pools
The most significant benefit of using chlorine tablets for your pool is its longer-term nature compared to granules. Once you get the right dosage, you shouldn't have to add another chlorine treatment for at least a few days.
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
Things that cause low free chlorine levels are excessive sunlight, high bather loads, and improper water chemistry. Not having enough chlorine in your swimming pool will also cause the little bit of chlorine that's in there to be used up faster too.
