Chemical Name: Hydroxyethylidine-1,1 Diphosphonic Acid
Function A sequestering solution to inhibit scale formation and mineral precipitation in spa baths.

Dosage Instructions

To prevent scale or stain deposit
  • Initial Dose: 50ml per 1000 litres (220 gallons)
  • Weekly Dose: 20ml per 1000 litres (220 gallons)
To Remove Scale that has been Deposited
  • As a guide add 2 litres per 1000 litres (220 gallons)
  • Run the spa/hot tub circulation for 24 hours
  • Drain the spa/hot tub and rinse out before filling.
Please note: The process of stain and scale removal is slow so for very high stain or scale levels apply a second dose after about a week rather than a single larger dose.

Pools: As an initial dose add 1 litre per 10,000 gallons of pool water. As a maintenance dose add 500ml per 10,000 gallons on a monthly basis.
