Nature2 Spa Stick Natural Spa Pool Purifier

The Nature2 Spa Stick is a mineral based spa water purifying system that uses silver, zinc and copper to kill bacteria and algae which reduces the load on sanatisers. Nature 2 sticks also soften the water making your water feel better.

In most cases, you will still need to use a small amount of sanitser. We recommend Spa Store Hydrogen Peroxide which is chlorine-free.

We recommend this shock for use with the Nature 2 Stick: WPQSHOCK1

You cannot use Nature2 with any sanitisers that contain Bromine as it stops the Nature2 stick from working.

The Nature2 Spa Stick automatically disperses silver and zinc ions into your spa, maintaining your water quality while reducing chlorine requirements.

Silver is an effective bactericide

Copper and zinc are used to combat algae

Additional minerals soften the spa water.


  • Not affected by heat or swimmer load.
  • Reduces stinging eyes and skin irritation.
  • No moving parts or electricity required.
  • Use with an approved oxidiser for a safe, clear spa.

How does N2 work?

The silver, copper (express & professional) and zinc (spa sticks) metals are attached to a ceramic substrate; due to its large surface area we are able to maximise surface exposure to the water.

As water flows through the Nature2, 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 pool 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, due to the fact that the cartridge only contains enough copper to raise the pool water to 0.02 to 0.06ppm.

Cartridge Contents: Silver and Zinc (Zinc is substituted for copper, which is less reactive with heating systems in spas.)

Spa Volume: 2000L

Running Time: 4 hours per day

Purifier life: 4 months


We recomend that the nature 2 stick is put in the filter well next to the filters in Vortex, Fisher, Banff, Arcadia and most other spas, not in the filter (as is stated in the N2 instructions designed for specific filters). This will limit the chance of the Nature 2 stick becoming lodged in the filter stand pipe.

Sanitiser:Potassium peroxymonosulfate (Spa Shock), Sodium dichloroisocyanurate or Lithium hypochlorite (lithium)

Compatibility: Not to be used with Bromine or Biguanide products

Start up Instructions:

1. Drain and refill your spa with fresh water.

2. Test and balance the spa.

3. Insert the Nature2 spa stick inside the cartridge filter

4. Add 3 tablespoons (63 grams) of Potassium peroxymonosulfate or 1 teaspoon (7 grams) of Dichlor

Maintenance Instructions:

1. 15 min before each use add 1 tablespoon (21 grams) of Potassium peroxymonosulfate (Spa Shock)OR one third of a teaspoon (2.33 grams) of Dichlor.

2. Once a week shock the spa with 3 tbsps(63 grams) of Potassium peroxymonosulfate OR 1 teaspoon of Dichlor (7 grams). All of these amounts are for per 1000lts rate.

3. The use of an efficient ozone generator with Nature2 will reduce the need for oxidisers (Dichlor and Potassium peroxymonosulfate)

4. Use 2 tablespoons of Potassium peroxymonosulfate as a shock once a week. If the spa has heavy use add 1 tablespoon every 3 days

5. Test and balance the spa weekly (Because of the small quantity of water, small changes can dramatically change the balance)

6. Remove the spa cover when shocking to allow the water to breathe and oxidise (20 to 30 mins)

Nature2 Stick Q & A:

Q: Is Nature2 an ioniser?

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

Q: Will Nature2 stain my pool?

A: 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

Q: Do I need to use Chlorine with Nature2?

A: YES, 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. A chlorine level of 0.6 – 1ppm is adequate to fill this function

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

A: YES, The spa or pool is treated as normal, balancing and stabilising chemicals are to be used to maintain the water.

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

A: 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.

Q: How can I test if the Nature2 is working?

A: 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.

Q: Is the Nature a filter?

A: 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.

Q: When do I replace the cartridge?

A: Depending on which Nature2 model you have cartridges for the CF and Sap stick will need replacing after 4months. The remaining models last for 6 months (Professional, Premium, Above Ground and Express)

Q: Where is Nature2 located on the pool system?

A: After the filter and before any electrode assembly of a salt chlorinator; Before an injection point of a standard automatic feeder unit.

A feeder point which is situated prior to the pump because it works on suction will not affect the Nature2’s performance due to the small amount of chlorine injected at this point.
