Is Sea salt safe to use in your hot tub?

Sea salt can be used in a hot tub, but it is important to note that it can affect the pH balance of the water and cause damage to the hot tub's components over time. Sea salt contains minerals such as magnesium, calcium, and potassium, which can build up in the hot tub's pipes, pumps, and heater, leading to corrosion and scale formation. Additionally, the high concentration of sodium in sea salt can increase the risk of skin irritation and eye damage.

Therefore, if you choose to use sea salt in your hot tub, it is crucial to monitor the pH level and alkalinity regularly and adjust it as needed. It is also recommended to rinse the hot tub thoroughly after each use to remove any residual salt and prevent build-up.

Alternatively, you can use hot tub-specific water care products, such as bromine or chlorine tablets, which are designed to maintain the appropriate chemical balance and sanitize the water without causing damage to the hot tub's components.
