Some pool owners believe that their hot tub is just a tiny version of their main swimming pool. This is simply not the case.
The purpose of a hot tub is very different than that of a swimming pool. Consequently, the way the water in a hot tub is treated and maintained needs to be unique.
The biggest and most obvious difference between hot tub water and swimming pool water is the temperature. Pool water typically is about 82 degrees F, while a hot tub is frequently set between 102 and 104 degrees F.
That temperature variation means that there are exponentially more opportunities for bacteria to grow in a hot tub. Plus, when you sit in a hot tub, the pores on your skin open up wider, making bathers more susceptible to skin infections.
Caring for Hot Tubs
when hot tubs are not properly maintained, the water can be responsible for such common problems as rashes and urinary tract infections. Bacteria growth also can cause cloudy water and cause damage to the hot tub’s surfaces and mechanical equipment.
The best way to control bacterial and viral growth is through sanitizers. Not only do sanitizers such as chlorine and bromine keep hot tub water smelling fresh, but they are very effective at disinfecting hot tube water.
The proper reading for bromine is between 3.0 and 5.0 parts per million, and for chlorine its 1.5 to 3.0 ppm.
Non-chlorine hot tub shock treatments eliminate odors and reduce irritating contaminants, resulting in clear, fresh water. Due to the high temperature and more frequent use, hot tubs generally require higher sanitizer levels, as well as more heavy-duty oxidizers to eliminate bather waste and maintain sparkling, clear water.
Like your swimming pool, maintaining the proper pH balance for your hot tub is essential for user safety. The pH level measures how acidic or basic your water is.
If it’s not kept in check, it can not only present a physical danger to bathers, but also affect your equipment, such as your pump seals, heating elements, and internal gas fired heaters.
