Can Any Spa Use Saltwater?

Saltwater spas are becoming increasingly popular each year. It seems like almost every spa now offers a saltwater option for the sanitation method, but can any spa use saltwater? The answer is yes — any spa can use saltwater! However, there are a few things spa owners need to keep in mind before making the switch.

How Does Saltwater Sanitation Work?

Saltwater spas use a process called electrolysis to sanitize the water. The salt interacts with the cell/generator to create a pure form of chlorine to sanitize the water as the saltwater passes through the system. To put it simply, the salt (sodium chloride) is converted to chlorine as it passes through the generator. This chlorination process is known for being gentler on both the skin and eyes than traditional chlorine-based sanitizing methods while still being an unbelievably effective way to kill bacteria. The spa will still need other chemicals to maintain the proper balance, but with a saltwater chlorine generator, you’ll simply need the right kind of salt to sanitize the hot tub. 

How Much Salt Do Saltwater Spas Need?

The amount of salt needed for saltwater spas can vary depending on the size and type of spa. Spa salt is also available in different grain sizes. In general, saltwater spas require between 2-4 pounds of salt per 100 gallons of water. The type of salt used in saltwater spas is also important. Most saltwater spas use sodium chloride. However, spa owners should never use any salt that is not created for spa use. Table salts, among others, contain impurities that can be detrimental to a spa’s equipment.

Saving Money with Saltwater

One of the biggest benefits of saltwater spas is that they are more cost-effective than traditional chlorine spas. The salt itself is inexpensive and, in general, saltwater spas require less maintenance than chlorine spas, which saves both time and money in the long run.

How to Convert a Hot Tub into a Saltwater Spa

Before spa owners make the switch to saltwater, they will need to allow all of the current chemicals to evaporate. Spa owners could also drain and refill their hot tub if they’d like to go ahead with their seasonal deep cleaning. Once the unit is ready to go, spa owners can purchase a saltwater conversion kit. Products like the Saltron® MINI Spa Sanitation System make saltwater conversion easy and stress free. The Saltron MINI is a saltwater chlorination system that is designed for hot tubs up to 600 gallons. The system comes with everything spa owners need to make the switch, including the salt, test strips, and detailed instructions. Making the switch to saltwater is a great way to enjoy all the benefits saltwater spas have to offer! Not only are they more cost-effective, but they also require less maintenance. Plus, saltwater is a safer and more gentle option for those with sensitive skin.
