Important Safety Information
Use only as directed. Direct tablet contact may cause bleaching of spa surfaces. Do not apply the product when swimmers are in the spa.
Automatic feeding devices using these tablets must be free from other spa sanitizers to avoid the probability of an explosion. Spa Chlor Ultra 1" contains stabilizer, which can accumulate in spa water. Keep stabilizer within the 30 to 100 ppm range by dilution with fresh water.
Superchlorination with Spa Chlor Ultra 1" will also lower total alkalinity. Make sure total alkalinity stays within the recommended range.
