Looking for a natural and effective way to keep your hot tub clean? Nature2® Spa Stick uses minerals to sanitize your water, reducing the need for harsh chemicals. Read on to learn how to use Nature2® Spa Stick, including its benefits and more.

Owning a spa or hot tub requires regular maintenance to ensure its longevity and functionality. One of the most significant challenges in spa maintenance is keeping the water clean and clear. In this article, you'll discover what is Nature2® Spa Stick, its benefits and if it could be the perfect solution for spa owners wanting an eco-friendly alternative to heavy chlorine or bromine to keep their spa clean.

What is Nature2® Spa Stick?

Nature2® Spa Stick is a product designed to help maintain the cleanliness of your spa or hot tub. It is a small, cartridge-like device that contains minerals and other natural ingredients that help to sanitize the water in your spa.

The minerals in the Nature 2® Spa Stick release a small amount of silver and copper ions into the water, which works to kill bacteria and other harmful organisms.

The Nature2® Spa Stick is easy to install and can be used with any spa or hot tub.

The Nature2® Spa Stick should be used in conjunction with an approved spa sanitiser and you should always follow the recommended dosage on the sanitiser label to ensure your spa water is safe for us.

How does Nature2® Spa Stick work?

The silver, copper (express & professional) and zinc (spa sticks) metals are attached to a ceramic substrate. As water flows through the Nature2® spa stick, silver and copper particles are dissolved into the pool water.

Silver has a natural saturation point. This means that the silver can only reach a certain level in the water. The cartridge will then stop releasing silver into the pool. Dissolved silver concentrations can only rise to 0.01 to 0.06ppm which has no risk of staining.

Dissolved oxygen in the water attaches to bacteria. The dissolved oxygen laden with silver damages or destroys the bacteria.

Copper is not stored in reserve in the Nature2 cartridge but is all released on start-up. Copper levels cannot exceed the staining threshold of 0.2ppm, because the cartridge only contains enough copper to raise the water to 0.02 to 0.06ppm.

How to use Nature2® Spa Stick

We recommend that the Nature2® stick is put in the filter well next to the filters in Vortex™, Fisher™, Banff™, Arcadia™ and most other spas, not inside the filter (as is stated in the N2 instructions designed for specific filters). This will limit the chance of the Nature2® stick becoming lodged in the filter standpipe.

Start-Up Instructions

  • Drain and refill your spa with fresh water.
  • Test and balance the spa.
  • Insert the Nature2 spa stick inside the cartridge filter
  • Add 3 tablespoons (63 grams) of Potassium peroxymonosulfate per 1,000L or 1 teaspoon (7 grams) per 1000L of Dichlor to activate the Nature2® spa stick.
  • Compatible Spa Sanitiser: Sodium dichloroisocyanurate, Hydrogen peroxide or Lithium hypochlorite (lithium). Not to be used with Bromine or Biguanide products.

Nature2® Spa Stick Maintenance Instructions

  • Nature2® Spa Stick should be used in conjunction with an approved spa sanitiser such as chlorine, lithium or hydrogen peroxide. You should follow the manufacturer’s recommended dosage for these products on the product labels.
  • The use of an efficient ozone generator with the Nature2® Spa Stick can improve its effectiveness also.
  • Test and balance the spa weekly (Because of the small quantity of water, small changes can dramatically change the balance)
  • Remove the spa cover when shocking or adding sanitiserto allow the water to breathe and oxidise. Leave the cover off for 20 to 30 mins.

How much is Nature2® Spa Stick?

The regular price for this product is $79.95. Spa World™ has it on sale for $59.95

Nature2® Spa Stick FAQs:

Is Nature2® an ioniser?

NO, Nature2® absorbs organic and metallic impurities. Nature2® is not electrically fired.

Will Nature2® stain my pool or spa?

NO. There is a non-stain warranty with Nature2®. The silver works on a saturation point and there is not enough copper present in the cartridge to stain.

Do I need to use Chlorine with Nature2®?

NO. You can use hydrogen peroxide, liquid lithium or chlorine. Nature2® requires an oxidiser to activate the silver and copper. A small amount of oxidiser is also required to burn off the dead bacteria and algae.

Will I need to add other chemicals to my pool or spa if I use Nature2®?

YES, The spa or pool water is treated as it would be with any other chemical. Balancing and stabilising chemicals are to be used to maintain the water. It is recommended to use Nature2® in conjunction with an approved sanitiser to ensure water safety, cleanliness and clarity is maintained. Ensure you follow the recommended dosage instructions on the sanitiser label.

Can I use Bromine, Bromide or Baquacil in my pool or spa with Nature2®?

NO, With bromine or bromide-based chemicals, Nature2®’s silver ions will be inactivated. This may result in cloudy water. Biguanide products can also leave a tacky residual around the scum line of a pool or filter cartridge.

How can I test if the Nature2® is working?

There is no real chemical test unless you have a photometer to test for minute amounts of copper. The best test is visual, the water quality will improve and the water will become softer.

Is the Nature2® a filter?

No, a filter is required to remove particles and debris in and on the water column. Nature2® disinfects pool water by killing bacteria, algae and viruses. Total dissolved solids are captured on the ceramic substrate. When do I replace the cartridge? The cartridges for the Nature2® stick will need replacing after 4 months.

Where is Nature2® located on the pool system?

After the filter and before any electrode assembly of a salt chlorinator. Install before an injection point of a standard automatic feeder unit. A feeder point that is situated prior to the pump because it works on suction will not affect the performance of Nature2® due to the small amount of chlorine injected at this point.
