We are often asked why Saltwater Hot Tubs only carries Spa Chlorine Generators from ControlOMatic. It comes down to three key areas and alignment in our values and ideals. These include…


Just like Saltwater Hot Tubs is a family-owned business, so is ControlOMatic. Originally founded as Acu-Trol in 1993, the name was changed to better reflect the changing pool and spa industry. ControlOMatic started engineering and designing spa chlorine generators in 2005 and the line of chemical automation tools started in 2008.


For the last 30 years, saltwater pools have been in high demand due to improved water quality and the huge reduction in maintenance that a saltwater system provides. Until now, a smaller saltwater system designed for a spa or hot tub was not an option. The standard spa chlorine generators offered by ControlOMatic are very easy to install and do not require the spa to even be on or interfere with the current plumbing or electronics, simply add salt, place in the water, and turn it on.

The ChlorMaker, SmarterSpa and MegaChlor are saltwater systems uniquely designed for hot tubs and spas bringing the same water quality and maintenance reduction benefits that pool owners have enjoyed for years.

Simply turn the water in your hot tub into saltwater by adding salt (about a teaspoon per gallon), and then let our chlorine generator take care of your sanitation needs day after day. The salt requirements for our saltwater systems is very low, between 1,500 and 2,000 PPM, less than 6% of the salt concentration of the ocean, you most likely will not be able to taste the salt.

Chlorine generation from salt water has been around for a very long time and has been very popular for swimming pools since the early 1970s. ControlOMatic introduced the first chlorine generator specifically designed for spas and hot tubs back in 2005, the first model was called the ColorChlor, in addition to making chlorine it also provided lights which worked well for older spas.

Saltwater chlorination is a desirable alternative to packaged chlorine and can provide a reduction in operating costs to maintain the spa as well as a much better experience when in the water.


ControlOMatic remains dedicated to bringing innovative, cutting edge, and value driven products to the pool and spa industry. Like the team at Saltwater Hot Tubs, everyone at ControlOMatic is dedicated to helping consumers find the ease and enjoyment of owing a pool, hot tub or spa.

ControlOMatic remains committed to the continual improvement of spa chlorine generators, with new research and design projects on-going all the time. Be sure to follow the Saltwater Hot Tubs team on Facebook, as we share news of new product releases or enhancements to existing units.
