Double your pool pleasure with DuoClear®!

Imagine not having to buy or store chlorine on a regular basis again. Imagine not having to constantly monitor and balance your pool water. It’s possible with DuoClear, the new revolution in salt systems. The DuoClear system utilizes Nature Mineral Purification and Zodiac® Salt Water Chlorination technologies, two of the leading pool sanitizing systems on the market. The innovative use of these technologies provides an extraordinarily efficient, and effective sanitizing system that actually leaves pool water feeling fresher and gentler than you ever thought possible — automatically!


How does DuoClear work?


As salt water passes through the device, chlorine is produced in controlled amounts. The chlorine oxidizes bacteria and algae and then turns back into salt to be used over and over again. An added feature, available only on DuoClear, is the Nature2 mineral cartridge. The cartridge contains minerals which are released into the pool to control bacteria and algae growth – the same way Mother Nature does! This secret weapon allows DuoClear to produce chlorine in much lower amounts and produces unparalleled water clarity, softness and sparkle. With chlorine levels as low as 0.6 ppm, your pool will be much easier to balance and maintain and will feel like a fresh mountain stream.

Benefits of DuoClear:

    Low Sanitizer Levels

    Reduce chlorine to as low as 0.6 ppm! Fewer chemicals mean no more harsh odours, red stinging eyes, dry skin, or bleached swimwear.

    Easy Water Balance

    Low levels of chlorine makes it easier to keep pH low. Fewer fluctuations in chlorine and pH levels makes water more stable, and much easier to balance. Less time spent on chemical maintenance means more time for you to enjoy your pool and its fresh clean water.

    Improved Water Quality

    Salt water feels soft and silky, leaving your hair and skin feeling pampered. Minerals leave the water sparkling clear. With a reduced dependency on chemicals, your pool will feel noticeably fresh and clean.

    No More Algaecides

    Nature2 minerals provide a natural solution to control algae.

    No More Buying, Handling or Storing Chlorine

    Let DuoClear take care of these chores for you so you can spend more time enjoying your pool rather than maintaining it.

Control Panel Functions

  1. Chlorine Output: controls the amount of chlorine generated.
  2. Chlorine Output Lights: staged indicator lights show level of chlorine output.
  3. Super Chlorinate: function increases the chlorine output for 24 hours of running time. This is used when the pool needs extra sanitizing after heavy use or rain.
  4. Add Salt Light: indicates the need to add salt to pool.
  5. No Flow: light will come on if there is insufficient water flow in the electrode, usually caused by the pump not running or a blockage.
  6. Cartridge Indicator Lights: a series of 4 lights indicate the progressive life of the DuoClear Cartridge. Flashing red light indicates the cartridge needs to be replaced.
  7. ON/OFF Button: switches the DuoClear and filtration system on and off.
  8. Cartridge Reset Button: is used at start up of your new system or when the DuoClear cartridge is replaced.

Frequently Asked Questions

Click a frequently asked question below to see the answer.

After it's installed, will pool maintenance change?
Yes, you will reduce chemical use and maintenance time. Basket cleaning, vacuuming and water testing will be the same as before, but the water balance will be easier, meaning there's simply less to do.
Can Nature2 stain my pool?
No. With Nature2 minerals remain well below levels that might cause staining. In fact, Nature2 offers a "no-stain" guarantee.
Do I still need to use chlorine with Nature2?
Yes, you need to use a small amount of residual chlorine to ensure water sanitizing. With Nature2 you can reduce the level to just 0.6 ppm of a Health Canada registered sanitizer in pools. In spas, follow the recommendations of your spa manufacturer.
How do I know if Nature2 is working?
The best test is improved water quality; you'll notice a big difference. Visual clarity and sparkle shows Nature2 is working properly.
How often do I need to super-oxidize (shock)?
Because of the efficiency of Nature2, super-oxidation is needed less often. You only need to super-oxidize if the pool becomes dull or cloudy. The start-up of each new cartridge requires an initial shock with chlorine. Follow chlorine manufacturer's label/instruction to super-oxidize.
Is Nature2 a filter?
No. A filter simply removes particles and debris. You still need a filter when using Nature2 system.
Is Nature2 an "ionizer"?
No. Ionizers electrically discharge copper (or metal alloy) ions into water. Ionizers can deliver ions via an electrical current (electrodes) or salt dissolution.
Is Nature2 compatible with other products?
Nature2 can be used with every type of chemical treatment program available except biguanide products and copper-based algaecides.
Which products should be avoided when using, or planning to use, Zodiac Nature 2?
Chlorine-free disinfectants of the PHMB type (or "biguanides"): Baquacil, Revacil, Oxyline. Other products containing copper.
