The Next Generation of Spa Water Treatment
The ClearBlue pool ionizer hooks into your pool filtration system and releases microscopic mineral ions which control bacteria and algae. This allows you to reduce the chlorine, algaecide and other chemicals by up to 90%. The ClearBlue Ionizer costs less than a salt chlorinator and ClearBlue mineral pools are less effort to maintain than traditional chlorine or salt water pools.
The “Fountain of Youth” effect
ClearBlue releases silver ions into the water to help control bacteria and viruses. Silver has been used for centuries for medical equipment and wound dressings . Prior to the introduction of modern antibiotics, colloidal silver was used as a germicide and disinfectant. Since the beginning of the twentieth century surgeons routinely use silver sutures to reduce the risk of infection.
Today, ClearBlue combines ancient wisdom with modern technology to provide water that cleanses and rejuvenates the skin while you soak. You'll instantly feel the softness of the water and notice how clear it stays.
Part of a complete system for lowering chlorine concentration in your spa
According to EPA no approved spa sanitizer is 100% chlorine (or bromine) free. But with a ClearBlue, you can minimize the concentration, while maintaining water that is safe for you and your family. 
Keeps protecting while the spa or hot tub is turned off
ClearBlue ions remain in solution and control bacteria in your hot tub or spa even when the pump isn’t running. UV systems, which also help to control bacteria, only work when the spa is on and water is flowing through the UV chamber.
Will not corrode your tub, cover and accessories
ClearBlue ions are completely safe for your tub and cover and will never cause fading or corrosion. Ozone systems, which are frequently installed on spas to help oxidize organic waste, will also corrode your accessories and cover.
Easy, low cost hot tub and spa maintenance
Once the ClearBlue Ionizer is installed, you set it and forget it. You will spend less time balancing pH and stabilizing chlorine. You may need less algaecide and clarifiers. The electrodes that release ions are replaced about once a year.
How Does it Work?
It's all about the ions 
ClearBlue continuously releases harmless microscopic ions into the water that seek and destroy bacteria, viruses and algae. Ions are picked up by the water as it passes over an electrode that is installed into the plumbing of your pool or spa.
What's an ion?
An ion is a molecule where the number of protons and electrons is different, giving the molecule a net positive or negative electrical charge. Because of this charge, ions are attracted to bacteria, viruses and algae and destroy them on contact.
What's an electrode?
A ClearBlue Electrode is a metal fork that releases ions into the water according to the settings on the ClearBlue controller.
Combines ancient knowledge with modern technology
ClearBlue extracts a proprietary blend of pure elemental silver, copper and zinc ions to cleanse and purify the water, while leaving your skin smooth and soft after each swim or soak.
Controlled at the touch of a button
Ion levels can be adjusted to the size of your pool and tub at the touch of a button. A test kit included with your ClearBlue allows you to test and optimize the levels for your liking.
How Do I Install ClearBlue?
The ClearBlue comes with a PVC tee junction that can be placed anywhere in the plumbing of your pool or hot tub. Ideally, it should be placed as close to the water or filter as possible.The tee can be horizontal or vertical.
The ClearBlue electrode which houses the metal that creates the ions is threaded into the tee.
The ClearBlue controller is an electrical device that is fastened to a flat surface near the tee. A cord from the controller plugs into the electrode.
