Water balancing is the process of maintaining the correct chemical composition of your hot tub water to ensure that your chosen sanitizer works to maximum effect.
The importance of water balancing depends on the hot tub chemicals you choose to use.

Maintaining the Total Alkalinity within the correct range is the key to water balancing. If the TA is within an acceptable range the pH will be easy to balance and your sanitiser will work well.
Always balance the Total Alkalinity before the pH
Maintaining the correct pH will ensure your sanitiser works efficiently, protect the pumps and heater from corrosion and help to avoid problems caused by limescale build-up.
Correctly balances pH is essential if you are using Chlorine or Bromine as your primary sanitiser.
If you keep the TA and pH balanced you won't need to worry about scaling unless you live in a very hard water area.
If your water is very soft, you might need to increase the calcium hardness to unsure your sanitiser works efficiently and to control foaming.
