Hot tub and spa ionizer reduces maintenance and chemicals
The ClearBlue hot tub ionizer hooks into your hot tub filtration system and releases minerals into the water. Minerals assist in controlling bacteria and algae by augmenting the the chemical sanitizer. This allows you to cut the chlorine or bromine in half so the water smells better and feels softer on your skin.


Better for your skin
Minerals build up in the water and help control bacteria and algae. So, you can reduce the chlorine or bromine concentration. The lower chemical levels reduce skin dryness and irritation that can come from using hot tubs.
Always protecting
ClearBlue minerals keep assisting with bacteria and algae control, even when the pump isn’t running. The minerals infuse the water and work in every nook and cranny of the spa.


Easy on your hot tub
ClearBlue minerals are completely safe for your hot tub and cover and will never cause fading or corrosion.
Precise and measurable
Mineral ions can be measured with a test kit so you know they are in there and working. A flashing red light on the controller tells you when it’s time to change the mineral cell.


Low power
The digital controller requires a trickle of electricity and the minerals keep working while the spa is turned off. This helps keep your power bill low.
