Non Chlorine Shock will oxidise oils such as body oils, lotions, deodorant, dead skin cells, sweat, detergents or leaves from your hot tub water, helping to prevent or reduce foaming and to reduce strain on your hot tub filters. This can also reduce reliance on chemicals that should be used sparingly such as Anti-Foam.
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.
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.
How Does it Work? The main purpose of spa shock is to break-down organic waste contaminants which cause bad odors and cloudy or foamy hot tub water. It does this by oxidizing the water, which is the process of rapidly removing the outer electrons from contaminants in the water that the spa shock comes in contact with.
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.
If too much is added, it can cause the overall pH level of the pool to drop for a sustained period, which you'll then have to raise. Whereas, with a chlorinated shock, if you overdose the pool on it, all you have to do is wait a few extra hours for the sun to burn off the chlorine.
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.
You only need a small amount of chlorine to successfully sanitize your spa, so it's possible to overdo it if you're not careful. Too much chlorine can damage your hot tub and irritate your skin, eyes and lungs. Thankfully, reducing the chlorine levels in your hot tub is very easy to do.
The bottom line is that over-shocking is possible, but being responsible with your chemicals and timing will help you to avoid it as often as possible!
Add 2 ounces per 250 gallons of spa water. Pour into the hot tub with the circulation system running. Spa Selections Non-Chlorine Shock Oxidizer helps remove organic contaminants for fresh, odor-free and clear water.
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.
Non-chlorine is an oxidizer, meaning that it does a great job cleaning up oils and organic matter. However, it doesn't actually kill bacteria or algae—you need chlorine for that. Therefore, you always need to use non-chlorinated shock in conjunction with chlorine to keep your pool water healthy for swimming.
We advise everyone to shock their water once a week to reduce bacteria and impurities. You can do this with one of two products; chlorine shock or non-chlorine shock.
Shock Treatment (Oxidizer):
Dichlor – A form of chlorine used as both a sanitizer and a shock, typically used only when you refill your hot tub. Shock treatments oxidize (gasses off) old chlorine, oils, sweat, dirt, and other contaminants that can make your water cloudy and smelly.
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!
Dead skin and other elements like hair may end up dropping in the hot tub, leaving the tub in a mess. It is essential to shock the hot tub frequently – at least once every week. It is important to use Chlorine shocks as well as non-Chlorine shocks.
Is Spa Shock the same as Chlorine? Sodium dichlor shock is a form of chlorine and can act as both sanitiser and shock treatment. If you're using a chlorine-free shock product like MPS (potassium peroxy-monosulphate), then this will not have any chlorine in it.
The primary culprit of foam is failing to sanitize your hot tub water weekly or after heavy use, such as a hot tub party. Lotions, cleansers, makeup and even laundry detergent leave our bodies and swimsuits when we soak in water. Foam will appear if the pH balance of your hot tub water is off.
Hot tubs in particular generate a lot of bubbles and tend to have higher temperatures. This combination creates a gas called carbon dioxide very quickly. Carbon dioxide builds up and makes the pH go up. This is why hot tub owners, on a regular basis, need to add something to lower their pH and alkalinity.
A shock treatment takes care of this problem by oxidizing the organics in the water before they can feed the bacteria. It also helps get rid of sanitizer residue that remains after the sanitizer has done its job. Generally it is recommended that you shock your hot tub once a week – more often if it's seeing heavy use.
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.
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.
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.
