Spa water must be balanced – meaning the pH level, Total Alkalinity (TA) level and Calcium Hardness (CH) level, all need to be within certain parameters. This is so your chemicals work effectively. Chemicals like sanitiser – which eliminates harmful bacteria from growing in the water – won’t work properly if the water isn’t balanced.

The spa balancing parameters are:

pH:       between 7.4 – 7.6 

TA:       80 – 150 parts per million (ppm)

CH:       100 – 200ppm

You can measure these parameters by bringing in a water sample or measuring it yourself with a test kit or strips. 

Does this all sounds too complex?
There is an easier solution!

BioGuard Spa Perfect Balance is a unique all-in-one product that locks in your pH, and helps control your TA and CH levels. This perfect balance will maintain stable, comfortable pH for up to 60 days, when you can drain and refill your spa to ensure the water stays fresh. (Draining your spa regularly is general advice for spa owners, regardless of their water balancing routine. Poolcare recommends draining your spa approximately every 10-12 weeks depending on usage).

  • Built-in corrosion inhibitors.
  • Helps control pH and Total Alkalinity.
