  • pH Reducer – Used to reduce the pH and/or alkalinity level. It might also interest you to know that this is one of the most sought-after balancers for spas and hot tubs. The reason for this is that many spas and hot tubs have their pH and alkalinity levels beyond the ideal range and need to be reduced.

As an aside, you should also know that accurate testing of your spa or hot tub’s water level is important. This is because that would help you make use of the right balancers when the need arises.
