Advantages of a Saltwater Hot Tub

Increased Water Softness

Thanks to the fact that salt systems require fewer chemicals compared to systems in traditional hot tub models, the water quality is far more consistent. Clean water will stay soft for much longer before a drain and a refill are necessary. Having a steady and natural flow of chlorine reduces the risk of pain and discomfort that it can have on a person, not to mention dry hair, red eyes, and cracked skin.

No Unpleasant Odors

Some chemicals have incredibly distinct and unpleasant odors. Chlorine is one of those chemicals. It can stick to hair and skin long after a soak. Because saltwater systems prevent chlorine from mutating into chloramines and instead revert them into sodium chloride (table salt), there aren't any odors to worry about.

Easier To Maintain

Saltwater systems help to reduce the amount of maintenance and water care that is needed for spa owners. A salt water system will continue to function and sanitize spa water from the moment that it is set up. Higher-end salt water hot tubs can even control the amount of chlorine going into the spa water depending on how heavy the ho tub use is.

Hot tub owners should test the water using test strips once per week to make sure the system is functioning properly. However, there is no need to purchase bromine or chlorine tablets, which can save money and create a safer environment for kids and pets.
