Frequently Asked Questions

Click a frequently asked question below to see the answer.

How do I dispose of used cartridges?

The minerals inside Nature2 are harmless, so it is safe for disposal with other household trash.

What affects cartridge life?

Nothing — including filter run time, heavy use, hot weather, and water temperature.

When do I replace the cartridge?

Cartridges for pools last up to six months. Change your spa cartridge every four months.

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.

Is Nature2 a filter?

No. A filter simply removes particles and debris. Nature2 sanitizes pool water by destroying bacteria, which is too small to be caught by a filter. 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.

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.

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.
