How To pH Balance A Hot Tub

Best way to balance a hot tub is with small adjustments, retesting after 20 to 30 minutes. Be sure to consult the safety instructions on all chemicals you use.

Using 4-way test strips, test the water. Start by balancing pH with a target pH level of 7.2 to 7.6.

• If the pH is high, dissolve Dry Acid (sodium bisulfate) into a bucket of water then add it into the spa with the circulation running.
• If the pH is low, add a bit of Baking Soda to the tub with the circulation running.
• Make smaller adjustments to balance the Total Alkalinity to 80-120 PPM (parts per million). Getting the Total Alkalinity correct will hep maintain your pH, however it's accuracy is less important than pH.
• If the Bromine level is low add a few Bromine tabs to the dispenser.
• If Bromine is high, add humans.
• After using the spa, add a bit of Spa Shock to release the Bromine.
• Once in a while add an enzyme product such as Spa Perfect to prevent scum lines and reduce odor.
