You can use hot tub test strips to test the pH of the water. To use a strip, submerge it in the water for about 15 seconds. The strip will change color according to your water’s pH, and you can match that color to the label to identify it.

It is recommended that calcium levels remain between 175 and 275 ppm (parts per million). But keep in mind that the ideal calcium hardness depends on the type of hot tub you own. Make sure to check with your hot tub’s manufacturer for this information. Add calcium booster if calcium levels are low. If calcium levels are too high, drain water from the hot tub and add low calcium water to balance it out.

Bromine and chlorine in tablets are added to a dispenser that floats around the pool and gradually dissolves in the water. These chemicals in powder form are measured and poured directly into the water. Whether you use chlorine or bromine is up to you. Some people prefer bromine because it doesn’t have that chlorine bleach smell. However, it will break down from sun exposure, so it should only be used in spas that are not in direct sunlight. Some advantages to chlorine are that it is cost-effective, easy to manage in the water, and it’s very aggressive when killing bacteria.
