Frequently Asked Questions
Why do stabiliser levels matter with this sanitiser?
This is a stabilised chlorine product, so stabiliser can build up over time. If stabiliser levels become too high, chlorine becomes less effective at controlling algae and bacteria.
What should I do if stabiliser reaches 50mg/L?
Stop using this product until stabiliser levels fall below 50mg/L, and use an unstabilised chlorine product to maintain free chlorine levels in the meantime.
Why should stabiliser never be allowed above 100mg/L?
At very high stabiliser levels, chlorine performance is reduced further, making it harder to maintain effective algae and bacteria control.
Why is daily testing important with spa sanitiser?
Spa water conditions can change quickly, especially with warm water and regular use. Daily testing helps keep chlorine and pH in the right range for reliable sanitising performance.
Can I use this in an indoor spa or commercial installation?
No. This product is not for use in indoor pools or commercial spa installations.
Why does the required free chlorine level change with water temperature?
Warmer water places greater demand on sanitising control, which is why the minimum free chlorine level is higher when the water temperature is above 26°C.
