People who own hot tubs need to use certain types of chemicals in order to keep the tub sanitary. The list of hot tub spa chemicals includes products created specifically for sanitizing the interior of the tub. These sanitizers are designed to kill bacteria making the water safe for people to soak in. Some products are sold as liquid solutions owners need to pour into the tub, while others are designed as tub floaters with attached dispensers. The dispensers usually use bromide tablets and come with adjustable flow rate controls.
In addition to the products designed to keep the water clean and free of bacteria, there are also spa hot tub chemicals designed to keep the filter clean. The filter is designed to trap bacteria and debris which can float in the water and be recycled through the internal pump system. Cleaning solutions can also be used on the external parts of the tub as well as on the cover. Most hot tub owners prefer to leave the water inside the tub between uses, rather than empty it out and refill it. The water inside the tub creates moisture which gets on the surface areas around the rim and inside the cover. It is important to use the right type of cleaning solutions to kill any bacteria which could turn into mold or mildew.
There are also a number of products available to help keep the pH level of the water in balance. Water can also contain alkaline and calcium, which can leave unattractive deposits along the outer edge or on the inside of the tub. Products are available to keep these substances in check so they do not accumulate in large amounts. There are also a number of water testing kits available to help owners determine the mineral concentrations inside their tubs.
