Clean, Comfortable Spa Water Starts with Purify
Every Iluka routine begins with properly sanitised water. Iluka Purify is made for the control of algae and bacteria in spas and hot tubs, using stabilised chlorine to help keep the water clean, protected and ready to enjoy.
What makes Purify different is the addition of Borax. Alongside its sanitising role, Borax helps soften the feel of the water and supports pH stability, making spa care easier while giving the water a more enjoyable, luxurious feel.

Features & Benefits
- Controls Algae and Bacteria: Sanitises spa and hot tub water to help maintain clean, protected water.
- Stabilised Chlorine Formula: Uses SDIC, a stabilised chlorine source that is effective across a wide pH range.
- Concentrated Sanitising Blend: Delivers effective spa sanitation in a simple, economical dose.
- Includes Borax: Helps soften the feel of spa water for a more comfortable and luxurious bathing experience.
- Supports pH Stability: Borax assists with pH stability, helping make spa water easier to maintain.
- Suitable for Hot and Cold Water: Suitable for spas, hot tubs and swim spas across a range of water temperatures.
How to Use
- Test the spa water with a reliable test kit to check free chlorine and pH levels.
- Calculate the required dose according to your spa volume and test result.
- Add Iluka Purify to the spa water as required to maintain the correct free chlorine level.
- Allow the water to circulate so the sanitiser can distribute evenly.
- Re-test regularly and adjust as needed to maintain the required sanitiser level.
Dosage & Coverage
- Standard Dose: Add 6g per 1,000 litres of spa water
- Frequency: Check sanitiser levels daily or after each use, and add Iluka Purify as required
Important Usage Information

- Do not exceed 50mg/L of isocyanurate.
- Do not use this product in indoor pools or commercial spa installations.
- Always add chemicals to water, never water to chemicals.

The Iluka Sea-Mineral Spa Experience
Iluka is an Aboriginal word meaning “near the sea”, and the feeling of being in a sea-like environment is at the heart of the range. Iluka Sea Minerals by Lo-Chlor brings together mineral comfort, water clarity and simple spa care to help create a more natural, luxurious and enjoyable spa experience.
Inspired by the calming feeling of being near the sea, Iluka transforms spa care into something softer, fresher and more rewarding — less like maintenance, and more like a calming ritual.

Frequently Asked Questions
How is Purify different from Eliminate?
Purify maintains the sanitiser level in the water. Eliminate is a chlorine-free shock treatment used to oxidise contaminants, reduce combined chlorine and help restore sparkle. They perform different roles in the Iluka routine.
Why does Purify contain Borax?
Borax helps soften the feel of spa water and supports pH stability. This gives Purify a comfort and maintenance benefit beyond standard sanitising.
When should I add Purify?
Check the sanitiser level daily or after each use, then add Purify as required. The amount needed depends on your spa volume, water temperature, test result and recent spa use.
Can Purify be used in swim spas?
Yes. Purify is suitable for spas, hot tubs and swim spas. Always dose according to the water volume and test results.
Can Purify be used in indoor pools or commercial spas?
No. Purify should not be used in indoor pools or commercial spa installations.
