Mineral spa hydrotherapy
The ClearBlue hot tub ionizer hooks into your hot tub filtration system and releases minerals into the water. Natural mineral spas have been enjoyed around the world for thousands of years. Hot water infused with minerals is relaxing, rejuvenating and great for your skin. Now, this ancient form of hydrotherapy is available in your own backyard.
Great for your skin
ClearBlue mineral spas infuse the water with natural minerals that leave your skin feeling soft after every soak.
ClearBlue minerals keep controlling bacteria and algae in your hot tub or spa even when the pump isn’t running. UV light and ozone systems only work when the spa is on and water is flowing.
Easy on your hot tub
ClearBlue minerals are completely safe for your hot tub and cover and will never cause fading or corrosion. Ozone systems, which are frequently installed on spas to help oxidize organic matter, can sometimes corrode your accessories and cover.
Precise and measurable
Mineral ions can be measured with a test kit so you know they are in there and working. It's easy to tell when a new electrode is needed. Flow based mineral cartridges have no way to test the level in the water or track how much is left.
The digital controller requires a trickle of electricity and keeps working while the spa is turned off. This helps keep your power bill low.
