Some users recommend the use of chlorine shock material periodically and also a small amount of a non chlorine sanitizer each day.

Water Care Key Facts

Here are some useful facts about how to treat spa water:

Test & Balance
You should always test the water before adding any treatment. To prevent damage from corrosion or scaling, as well as bather discomfort. The aim is to balance 3 perameters of the water chemistry- pH, Total Alkalinity and Calcium Hardness.

Test Strips
Always keep your test strips in a sealed container to protect them from moisture. Careful not to touch them with wet fingers.

Due to their small volume hot tubs and spas are prone to fluctuations in pH, so that’s why it must be monitored closely.
Low pH- Water with a low pH can cause eye and skin irritation, corrosion of metal components and chlorine loss.
High pH- Water with a high pH can cause eye and skin irritation, lead to crusty deposits on surfaces, cloudy water and poor chlorine disinfection.

Total Alkalinity
Total alkalinity has a great effect on the pH balance of the water.
Keeping Total Alkalinity in its proper range will prevent wide swings in pH.
If the Total Alkalinity is too low then the pH becomes difficult to control. High total alkalinity causes pH to drift upward and makes lowering it difficult.

Calcium Hardness
Water with high calcium hardness has a greater tendency to deposit rough, unsightly scale on surfaces and equipment.

The aim is to always keep an adequate residual of free chlorine in the water, while eliminating all combined chlorine.
Chlorine’s sanitizing and oxidizing effectiveness is highly dependent upon the pH of hot tub water.

Bromine has some advantages over chlorine for hot tubs and spas.
Bromamines are good sanitizers and don’t cause an objectionable smell or any irritation as with chlorine.
When it is is added to water, it forms the sanitizer and oxidizer.
Another benefit of bromine is that its effectiveness isn’t significantly affected by pH changes in the range normally encountered in hot tubs.

Bromine is very susceptible to degradation by the UV rays in sunlight, so always keep your hot tub covered when not in use.

Some hot tubs have ozonators which create ozone gas which is an extremely powerful (but very short-lived sanitizer) and oxidizer.
Ozone doesn’t eliminate the need for a chlorine or bromine residual, but their use can be greatly assisted and reduced.
