Liquid Spa Up (2lbs) gently increases and raises pH to help properly balance water. It does not require any mixing or diluting, so just pour liquid directly into your hot tub, per label directions. Liquid Spa Up is compatible with chlorine, bromine and biguanide sanitizers.
Note: We recommend having your water tested professionally either every 2 weeks or once a month to ensure all chemical levels are correct. This will help maintain crystal clear water & extend the life of your spa.
