  4. Continuous Treatment: Add weekly, 15ml Aquablanc A Combination Liquid per 1,500 litres of spa water.
  5. Aquablanc A Combination Liquid can be added directly to your spa water whilst the spa pump(s) are turned 'on' to aid distribution.
  6. Aquablanc O2 Tablets should be dosed via a floating dispenser.
  7. Test the oxygen level 1 hour after application of O2 Tablets.  The oxygen level should be between 10mg/l(ppm).
  8. A weekly application of AquaSPArkle Spa Fusion is recommended.
