Salt Hot Tubs

The Clean, Simple, Low-Maintenance Way to Enjoy Your Spa

If you’ve been researching salt hot tubs, chances are you’ve heard they offer cleaner water, fewer chemicals, and easier maintenance. With major brands like HotSpring®, Caldera®, and Master Spas promoting salt systems heavily, it’s clear why salt hot tubs have become one of the most requested features in the spa industry.

But here’s the truth most shoppers don’t hear:
Not all salt systems are created equal.

If you want the true benefits of salt hot tubs—without the downsides—you need the right salt system. That’s where Blu Fusion™ Automated Bromine Generation stands apart.

Why Salt Hot Tubs Are So Popular

Homeowners love salt hot tubs because they offer:

Softer, more comfortable water
Reduced chemical handling
Consistent sanitation
Less odor than traditional chlorine
A more “natural” soaking experience

Salt systems automatically create sanitizer from salt that’s already in the water. That means less manual dosing, fewer harsh chemicals, and more time enjoying your spa.

The Problem with Traditional Salt Hot Tub Systems

Most major salt hot tubs on the market use chlorine-based salt systems. While they are marketed as low maintenance, many still require:

Weekly oxidizer shocking
Calcium levels below 75 ppm (often requiring expensive water treatment)
Additional chlorine added regularly
More frequent cell replacements
Short warranties (often 1 year or less)

These hidden steps can turn a “low-maintenance” salt hot tub into more work than expected.
