What Chemicals Do You Need For Your Hot Tub?
There are two necessary types of hot tub chemicals: stabilizers and oxidizers. Stabilizers are sanitisers like bromine and chlorine that effectively kill bacteria and maintain proper pH balance in the hot tub.
Sanitizers like bromine and chlorine cannot be used simultaneously. When you are stabilizing your pool, choose only one chemical of the two.
Bromine
As has been mentioned in the list of reviews, bromine is more stable than chlorine at higher temperatures. Because of this, bromine is typically the chemical of choice for stabilization. However, because of the effect that UV rays have on bromine, it is not ideal in every situation.
If your hot tub is directly exposed to sunlight, beaming it with UV rays daily, then you should consider using chlorine. Although it is less stable at higher temperatures, the stabilizing effect is similar as long as treatment is properly kept up.
Chlorine
It is a more active sanitiser than bromine as well. Chlorine, however, stops working after it has acted on bacteria, whereas the lifespan of bromine is longer and continues after initial sanitization.
Chlorine is also notorious for irritating skin and giving off an unpleasant, noxious odor, which not many people desire when relaxing in a hot tub. Not all people are irritated by it, and some situations even call for the use of chlorine, such as hot tubs exposed to direct sunlight.
In addition to the stabilizers, you’ll need an oxidizer. This is what shock agents are. The shock agents clear cloudy and contaminated water while the stabilizers work on killing bacteria and maintaining pH balances.
Some products on the market are both stabilizers and oxidizers, minimizing the steps needed to maintain a healthy hot tub.
Because of its importance, the stability of the water, and its effect on safety, pH test kits should also be used on your hot tubs. While they are not alone as a chemical of necessity for your hot tub, they’re essentially a mandatory accessory for stabilizers and oxidizers.
Testing should be carried out on your hot tub water frequently, nearly daily, if possible.
Tips on Choosing a Hot Tub Chemicals
The following is a list of tips for choosing hot tub chemicals:
- Do research: If needed, read further about the differences between bromine and chlorine. Researching the two and getting a feel for the differences will go a long way. Additionally, use comparison charts between similar products to give yourself an idea of which product is best suited to your needs.
- Ask others: Ask other hot tub owners what they use in their hot tubs and why. They’ll be able to provide you all sorts of information all the way down to why they chose a specific product. Also, search the web for hot tub communities/groups and see what they have to say about hot tub chemicals. If you have a question of your own, post it and wait for a reply.
- Read reviews: Reviews are a straightforward way to get a general idea about a product’s success. Many people like to leave tips and pointers that aren’t noted by retailers in their reviews, which provides an extra layer of info. Just be wary of all reviews and take them with a grain of salt because they are mostly subjective.
Factors To Consider When Buying Best Hot Tub Chemicals
The factors to consider when buying hot tub chemicals are mostly centred on your hot tub model, hot tub location, and personal preference.
The first factor is your actual hot tub model. Not all hot tub models are created equal. Depending on your model, such as hot tubs with vinyl walls, you may or may not be able to use certain products. While most, if not all, of the products reviewed in our list are safe for all types of hot tubs, some products are not.
Be careful to read full descriptions about the contents of the stabilizers and oxidizers you are buying to be sure they are compatible with what you have. Again, they almost always will be, but it is safest to know.
Another important factor is the location of your hot tub. As has been noted throughout the review, if your hot tub sits under or is exposed to direct sunlight, you should be using chlorine because UV rays destabilize bromine.
If your hot tub is heavily shaded, covered, or inside, then the hot tub chemical choice is up to you (though we recommend bromine solutions). Bromine is also less intense, making it ideal for enclosed or less aerated places.
The final factor to consider is your personal preference. Some people are not tolerant of the chlorine solutions, citing distasteful odors and skin irritation. However, for those without intolerance to chlorine, the choice of how to stabilize and oxidize your pool is yours.
By knowing how much effort you are willing to put into the upkeep of your hot tub and what your bodily tolerance is for each cleaning solution, you’ll be able to narrow down your options markedly.
Best Hot Tub Chemicals FAQ
What are the most important chemicals to use in a hot tub?
The three most important chemicals for hot tub water cleaners are chlorine or bromine, pH adjuster, and total alkalinity increaser.
Chlorine or bromine sanitizes the water, the pH adjuster balances the pH, and the alkalinity increaser buffers the water against pH fluctuations.
How often should I add chlorine or bromine to my hot tub?
A: You should check and adjust the chlorine or bromine levels in your hot tub daily. Most experts recommend keeping the chlorine level between 1-3 ppm and bromine between 2-4 ppm. Add chlorine or bromine as needed to maintain proper levels.
What is shocking a hot tub and when should I do it?
Shocking a hot tub means adding extra chlorine or non-chlorine shock to oxidize contaminants and reactivate the sanitizer. You should shock your tub weekly and after heavy bather loads. Use chlorine shock or non-chlorine shock like potassium peroxymonosulfate.
How often should I test the pH and alkalinity of my hot tub water?
Test the pH and alkalinity at least 2-3 times per week. The ideal pH range is 7.2-7.6. Total alkalinity should be between 80-120 ppm. Test strips or digital testers make testing easy.
When should I change the hot tub water completely?
Drain and refill your hot tub every 3-4 months. More frequent water changes may be needed with heavy use. This removes built-up contaminants and minerals from the water.
Is oxidizer the same as shock?
No, an oxidizer is not the same as shock, an oxidizer is a chemical that promotes burning, while shock describes a violent impact force. They are distinct concepts, though oxidizers may contribute to explosive shock waves. But the terms are not alike.
Best chemicals for inflatable hot tubs?
Bromine tablets provide strong sanitation without the harshness of chlorine. Look for slow-dissolving tablets from trusted brands like Leisure Time or SpaGuard.
Are hot tub chemicals safe?
Hot tub chemicals are safe when used properly according to the manufacturer’s directions. Always wear gloves and eye protection when handling chemicals. Store chemicals securely out of reach of children and pets.
