How to use
Simply immerse your water tester in your hot tub or pool, or fill a water sample into the chambers, add a tablet, and read the results. The water will change colour and the comparison scale makes it easy to read the values.
Blue Horizons uses the popular BOAST system of chemicals, to have hot tub or pool water to boast about:
B Balance your pool water for bather comfort & maximum chemical efficiency
O Oxidise to establish a sanitiser level then weekly to destroy bather wastes.
A Algae prevention. Stop algae establishing themselves in your pool water.
S Sanitise. Maintain a constant sanitiser level to prevent & kill bacteria.
T Testing. Test your pool water to ensure the correct levels.
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.
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.
