Instructions for Use
Preparation for New or Refilled Spas:
-
If your spa is new or has just been refilled, start with a non-chlorine shock treatment to remove any initial contaminants and prepare the water for Active O2 use.
-
Use a suitable non-chlorine shock, such as HTH Non-Chlorine Shock or a similar product, and circulate for at least 1 hour.
Initial Dose:
-
Add 25g of O2 Gentle Granules per 1,000 litres of water with the pump(s) running.
-
Immediately add 40ml of Aqua Sparkle Active O2 Gentle Liquid per 1,000 litres to activate the sanitiser.
Weekly Maintenance:
-
Before each use, add 15g of O2 Gentle Granules per 1,000 litres directly to the water.
-
Once weekly, add 10ml of Active O2 Gentle Liquid per 1,000 litres.
-
Use active oxygen (MPS) test strips to ensure levels are maintained between 5–10 mg/l.
Optional Weekly Clarifier:
-
For added clarity and bather comfort, use Aqua Sparkle Spa Fusion weekly to remove excess organic material and maintain sparkling water.
