Adding a hot tub to your home can be a real luxury but keeping your hot tub clean takes effort. Proper maintenance is very important to keep your hot tub in top running condition. Before you start cleaning your hot tub you should be aware of required pH balance, alkalinity levels, sanitizers, and oxidizers.
Sanitizers kill the bacteria that can grow in warm water. There are 3 types of sanitizers i.e. Chlorine, Bromine and Biguanide. Chlorine can be used in a different concentration in hot tubs. There are chlorine tablets and chlorine granules created specifically for hot tub use. Bromine is similar to chlorine but is less harsh on the skin and does not smell as strongly. In fact, the bromine tablets you can put in your spa are made of chlorine and sodium bromide. Most bromine solutions use a floating "brominator" that allows the bromine tablet to slowly dissolve into the water over time. Biguanide sanitizers are a non-chlorine, non-bromine product that kills bacteria by attacking the cell wall. The elimination of organics is accomplished with a hydrogen peroxide-based oxidizer used to "burn" off the organic matter and keep the water clear. This system produces fewer odours than chlorine or bromine and does not "gas off" at spa temperatures.
Oxidizers: Ozone is released into the spa water to oxidize and destroy bacteria and other contaminants (viruses, algae, yeast, cologne, sun tan lotion, saliva, urine, etc). Ozone is an oxidizer and it reduces the work of the sanitizers and lowers the level of sanitizers needed in the spa to keep it clean. The ozone process requires that your hot tub is equipped with a piece of equipment called an "ozonator." Even if you have an ozonator, you will need to supplement your water with a low level of sanitizer like bromine or chlorine.
PH and Alkalinity Balance: Alkalinity Increasers increase the total alkalinity of your hot
