How hard is it to maintain the water in a hot tub?
That depends on the hot tub. Look for a quality water treatment system on the hot tub. Ozone is a common oxidizer used to automatically sanitize the water. Look for “CD” ozone versus “UV” ozone. A CD ozonator is more effective and longer lasting. How is it delivered? Does it have a mixing chamber to interact and be mixed with the water, thereby making it more effective? Or does it have a simple “Venturi” as a delivery system that doesn’t work as effectively? A marketing ploy today is to advertise the ozonator with the hot tub, but make it as cheap as possible. What kind of filter does it have? A Cartridge filter is the most common, (needs to be cleaned frequently and doesn’t filter fine particulates) but there are quality filter systems that filter much finer, and are disposable. These types also eliminate the need for some of the chemicals you would ordinarily use.
