Enjoy a Chemical Free - maintenance free pool all season long!

Start with fresh, clean water - Place the POOL DISK into your skimmer or inside the filter housing - THAT’S IT!

No Maintenance - No Chemicals  - No Problem!

What It Does:

The POOL DISK creates chlorine-free water for swimming pools using passive ionization and catalytic oxidation, instead of constantly adding toxic, corrosive chemicals to the water.

Chlorine attacks organic matter, like your skin! Chlorine irritates your eyes, your nose, ears and lungs, and it leaves your skin and hair dry and flaky. Studies have shown that long-term exposure to chlorine can be harmful to your health. Biguanide alternatives to chlorine cost a fortune, require constant chemical balancing, don’t work with regular pool chemicals and can still cause allergic reactions, not to mention having to deal with cloudy water and the residue inside your plumbing, your filter and on the pool walls.

One Disk will treat your pool, up to 10,00 gallons, for up to four months

What It Is:

The POOL DISK is a state-of-the-art form of KDF® copper-zinc media which has been molded into a semi-hard disk that looks a lot like a gold sponge. This form of KDF acts as a descalant and algaecide in the pool and maintains a bacteriostatic environment in the filter.

How the POOL DISK Works:

KDF works on an all-natural process that uses catalytic action and the redox (reduction/oxidation) principal of dissimilar metals. As water passes through the POOL DISK a chemical reaction causes zinc and copper hydroxides to form in controlled amounts. These controlled releases of copper and zinc oxides are carried into the filtered water where they kill bacteria and provide hostile conditions for algae and fungus growth.

As the water twists and turns through the POOL DISK's fibers the turbulent movement increases the contact time with the KDF, improving efficiency.

The filter is not subject to channeling or clogging, and no backwashing is necessary.

This means the water stays clean without chemicals, has no harsh, irritating side effects, and requires virtually no maintenance.

KDF also safeguards plumbing and equipment because they are protected against the corrosive effects of chlorine.

If excessive bather load or bad weather should cloud the pool all you need is a one-time shock treatment with potassium monopersulfate, followed by constant filtration to solve the problem.

The POOL DISK also helps neutralize slightly acidic water, helping reduce the use of pH chemicals.

These KDF products meet NSF Standards 42 and 61.
