One of the first questions people ask when they are thinking about buying a hot tub is:

“Is it easy to look after?”

And honestly, I completely understand why.

A hot tub should feel relaxing from the moment you lift the cover. You want warm, clean, inviting water ready for you and your family to enjoy — without feeling as though you need to become an expert in water chemistry.

That is why FreshWater IQ is such an exciting development from HotSpring.

FreshWater IQ is HotSpring’s most advanced water care system. It brings together three clever technologies — the FreshWater Salt System, the Smart Monitoring System, and the Dosing System — to help keep spa water clean, balanced, and easier to maintain. The aim is simple: less guessing, less measuring, and more confidence that your spa is ready when you are.

Softer Water, Fewer Chemicals

The foundation of FreshWater IQ is the FreshWater Salt System.

It works by converting dissolved salt into chlorine using a titanium cartridge, helping to keep the water clean without relying on traditional chlorine products. The benefit for customers is easy to understand: softer-feeling water, fewer chemicals to buy, and no harsh chlorine smell.

That makes a real difference to the way the spa feels.

The water feels gentler, fresher, and more natural. For many people, that is one of the things they notice and love straight away.

No More Guessing With Test Strips

The Smart Monitoring System is where FreshWater IQ starts to feel really intelligent.

Instead of relying only on test strips, the system automatically checks chlorine, pH, and salt levels every hour. The results are then shown clearly on the spa’s touchscreen with simple colour-coded guidance. Green means ideal, yellow means attention is needed, and red means it is time to act.

For me, this is one of the biggest benefits.

Water care becomes less about guessing and more about knowing. You do not have to stand outside wondering whether the colour on a test strip looks “about right”. The spa gives you clear guidance, step by step.

That confidence is exactly what makes ownership feel easier.

No Measuring, No Mess

Then comes the Dosing System.

This is the part that many customers will find a real game changer.

Three refillable cartridges sit neatly under the filter lid. When the Smart Monitoring System detects that the pH needs attention, the spa prompts the user on the control panel. The system then dispenses the right amount of pH Up, pH Down, or Phosphate Remover directly into the spa water.

No measuring.
No mess.
No over-dosing.

The customer stays in control because the system prompts them before dosing, but the spa does the careful measuring for them.

That is what I like most about it. It is clever technology, but it still feels simple and reassuring.

Control From Your Phone

FreshWater IQ can also work beautifully alongside the Hot Spring Spas App and Connected Spa Kit.

With the app, customers can monitor pH, chlorine, and salt levels, adjust the temperature, control lights and jets, activate a Clean Cycle or Energy Saving Mode, set a Soak Timer, and access FreshWater IQ controls from their phone.

The app is not essential, because the spa’s built-in touchscreen still gives full functionality, but it adds another level of convenience.

You can check the spa while you are at work.
You can adjust the temperature before you get home.
You can turn the lights on before you step outside.

It helps the spa fit around real life.

Less Time Maintaining. More Time Enjoying.

When maintained correctly with the full FreshWater IQ system, spa water can stay fresh for up to a full year. That means less draining, less refilling, and less hassle over time.

And really, that is what this is all about.

FreshWater IQ is not technology for the sake of it. It is technology designed to make hot tub ownership easier, smarter, and more enjoyable.

The Salt System helps create softer, cleaner water.
The Smart Monitoring System checks the water every hour.
The Dosing System gives guided, precise water care.
The app lets you monitor and control your spa from wherever you are.

Or to put it simply:

Soak more. Stress less.
