How often should I test my hot tub water?
We recommend you test your hot tub water daily whether your spa is in use or not
What should hot tub water be tested for?
Test your hot tub’s water for sanitiser levels - whether that’s chlorine, bromine or oxygen - along with pH and total alkalinity. This then allows you to make any chemical adjustments that may be required.
What is the best way to test hot tub water?
For quick and accurate detection, we recommend using test strips to check the levels of your water.
How long after shocking a hot tub can you test the water?
There is no set time to wait before using your hot tub. All brands give different recommendations, ranging from 20 minutes to 24 hours. However, before donning your swimsuit and stepping inside, we suggest using a test strip to ensure your chlorine levels are safe.
Top tip: Non-chlorine shock treatments don't sanitise the water. This means you can usually use your hot tub after approximately 20 minutes of adding the chemical.
