In today’s market there are several convenient methods available to test hot tub water and ensure proper balance.
Test kits and water testing strips use colour comparison to indicate what adjustments you might need to make to chemical levels. They generally test for sanitizer (chlorine/bromine), pH, TA and sometimes total hardness. Once your hot tub water is balanced, the most important factors to measure are levels of free chlorine/bromine and pH. You should test your hot tub water on a daily basis, and most importantly, before using it.
It is also a good idea to periodically take a water sample to your local hot tub dealer to verify the accuracy of your testing and check TA and calcium hardness, which could change after adding makeup water.
