The purpose of hot tub chemicals is to maintain the water at a comfortable temperature, provide a soothing environment and prevent the growth of bacteria and algae.If you have a spa with vinyl or fibreglass surfaces, use a non-chlorine shock treatment after each use to prevent algae from forming.
There are many different chemicals that you can use in your hot tub. The most common are chlorine, bromine and ozone. You do not need to use all three of these chemicals at once in your hot tub. However, the choice is up to you and depends on your preferences.
Below is Guide To Hot Tub Chemicals:
Chlorine: This is a very common chemical used in hot tubs because it is relatively cheap and easy to find. It also has a number of benefits that make it a great chemical for your hot tub. For example, chlorine works well in hot water (90 degrees F or more) and can even be used with bromine or ozone as part of a chemical balance system. Chlorine also kills bacteria effectively so it helps keep your water clean from harmful microorganisms such as algae or mold spores.
Bromine: Bromine is another chemical that can be used in place of chlorine for sanitizing your hot tub water. The main difference between these two chemicals is how long they last in your water before needing replenishing. Chlorine lasts anywhere from 12-24 hours whereas bromine will last anywhere from 72-96 hours before needing replenishing again.
Alkalinity is important because it keeps the pH stable in your hot tub. When the pH level gets too low, it can cause an odor problem or make your skin feel dry and irritated after soaking in the tub. A lack of alkalinity (too acidic) will also cause scaling on surfaces such as tiles or filters, which leads to mechanical problems with your hot tub system.
Bromine is another popular chemical used in hot tubs because it’s less irritating than chlorine and doesn’t give off any fumes that could irritate your eyes or nose like chlorine does when added directly into the water by accident during filling or draining your spa.
Other chemicals found in hot tubs include bromine or ozone, which can be used as alternatives to chlorine. Bromine is a liquid that smells like a pool, but has some disadvantages compared to chlorine: it has a lower disinfection capacity and it takes longer for its residual effect on pathogens to dissipate than chlorine does. Ozone gas is also used in many spas, but it is expensive and requires special equipment that must be installed by a professional service technician.
