A chemical imbalance has always been an issue to pool or spa owners. As much as possible, they always try to find ways to avoid it. So, knowing what’s best and what’s not becomes challenging, especially with lots of information available on the Internet.
Chances are you are skeptical about mixing both bromine and chlorine in your hot tub. Do you think they will both go well together? Well, these chemicals are similar in nature in the way they kill bacteria but react differently in a hot tub.
Is this possible or not? Keep reading to find out.
Can You Mix Chlorine and Bromine in a Hot Tub?
In the world of hot tubs, bromine has always been the best in disinfecting and killing bacteria because they are more stable in warm water. However, people are eager to know the possibilities of mixing both chemicals in the water.
Well, whether you choose chlorine or bromine for your tub, you shouldn’t mix both in water to avoid chemical imbalance. Also, avoid using both chemicals in the same feeder— be it a tablet or granular.
So why is it not recommended to mix both chemicals? Chlorine and bromine can react dangerously with each other when mixed, especially the granular ones.
I can say to you that combining chlorine and bromine is one of the most potent cancer-causing mixtures. Most chemical companies will definitely warn you against it, but some retailers might advise you otherwise. Obviously, to double their sales.
Bromine Vs Chlorine: Which Is Better for Hot Spa
How you weigh your choice among these two chemicals highly depends on their application. They are both effective in killing bacteria and keeping your pool clean, but how they do just that varies because of their molecular structure.
Bromine is very effective at varying temperature ranges and pH levels. That’s why it is more suitable for hot spas. In addition, they are soft to the skin and can continue to keep killing bacteria over a long period.
On the other hand, chlorine can dissipate quickly. So, it would require continuous topping to keep it active. When it comes to effectiveness, chlorine kills bacteria faster than bromine. Bromine also works cool but not as fast as chlorine.
Chlorine is less expensive than bromine. It’s easy to apply and can be stabilized when exposed to UV rays. It can also keep your water crystal clear just as bromine and remain stable at low temperatures, unlike bromine.
However, the downside of chlorine boils down to its difficulty in keeping pH level balanced. It’s irritating to sensitive skin and has this pungent smell. To keep the chlorine effect, you need to apply it more frequently. The fact that it’s less effective to temperatures above 70oF makes it not suitable for hot tubs
The only downside in using bromine is that the chemical is susceptible to UV light from the sun, making it less effective. This is a concern if you have an outdoor pool that is exposed to the sun. However, having a quality hot tub cover would eliminate this limitation.
In summary, for the hot tub, bromine is the best choice, no matter the cost. It’s all you need for your spa sanitation, especially when your spa is indoors, or you live in a warm climate. In addition, it’s less irritant which makes it perfect for sensitive skin.
Can You Use Pool Chlorine in A Hot Tub?
Questions like this once crossed my mind when I ran out of granular chlorine. After that, I often pondered upon it, but then, I decided to get information online to convince myself otherwise.
Well, it all goes down to what type of chlorine is in question. First, you need to understand that granular chlorine is quite different from liquid chlorine.
However, they might have similar ingredients on their label but are different in their strength and chemical composition. For example, liquid chlorine has a high pH of about 13, which is not suitable for low water volume like tubs. On the other hand, granule chlorine has low pH, making it best for your hot tub.
You also need to understand that swimming pools and hot tubs are built differently, and both are selective in the type of chemical to use.
One significant difference between both is the volume of water in them. Some pools have large water volumes. While it’s okay to use pool chlorine on a swimming pool, it is never advisable to use that on a hot spa due to the high chlorine concentration dispersed.
Another reason you wouldn’t consider using pool chlorine in hot tubs is because of the temperature. Due to the high heat in hot tubs, dropping liquid chlorine in them might not be suitable. The heat helps the tub to dissolve and disperse the chlorine quickly but not uniformly.
The chemical composition in liquid chlorine contains some stabilizers that might throw off your hot tub’s pH level, making it impossible to balance.
How To Shock a Hot Tub with Bromine?
Shocking your hot tub is relatively easy and seamless. If you have time, you can do that yourself without the service of a professional.
Here is an easy step-by-step method to shock your tub.
- First, you will need to adjust the pH level of your spa to between 7.4-7.6
- Then, take away your tub cover in preparation for the shocking process.
- Turn off the air jet but allow the circulating pump to keep circulating water at a minimum throughout the shocking process.
- Measure out the shock as directed from the label. Check the label in your shock to know the requirement and amount of shocks to use. Let it be proportionate to the amount of water you have in your pool.
- Gently add the shock to your hot tub.
- After some minutes, test the water to see if the chlorine level has dipped down to 5ppm. If it has, then you are free to use your tub. Worst-case scenario, you could wait for an hour or even a day before it will be safe to use. It all depends on the amount of shock used.
If you have spillage by any means, remember to clean immediately before causing damage to your tub. Also, keep all chemicals away from children.
Now you understand the importance of not mixing bromine and chlorine together in your hot tub water. It should never cross your mind and never an option when considering the chemicals to use for your spa.
Bromine has always proven the best choice among hot tub and spa owners because of its chemical composition that keeps the chemical stable at a high temperature.
